MAX 7000B devices use CMOS EEPROM cells to implement logic

functions. The user-configurable MAX 7000B architecture accommodates

a variety of independent combinatorial and sequential logic functions.

The devices can be reprogrammed for quick and efficient iterations

during design development and debug cycles, and can be programmed

and erased up to 100 times.

MAX 7000B devices contain 32 to 512 macrocells that are combined into

groups of 16 macrocells, called logic array blocks (LABs). Each macrocell

has a programmable-AND/fixed-ORarray and a configurable register with

independently programmable clock, clock enable, clear, and preset

functions. To build complex logic functions, each macrocell can be

supplemented with both shareable expander product terms and high-

speed parallel expander product terms to provide up to 32 product terms

per macrocell.

MAX 7000B Programmable Logic Device Data Sheet

MAX 7000B devices provide programmable speed/power optimization.

Speed-critical portions of a design can run at high speed/full power,

while the remaining portions run at reduced speed/low power. This

speed/power optimization feature enables the designer to configure one

or more macrocells to operate up to 50% lower power while adding only

a nominal timing delay. MAX 7000B devices also provide an option that

reduces the slew rate of the output buffers, minimizing noise transients

when non-speed-critical signals are switching. The output drivers of all

MAX 7000B devices can be set for 3.3 V, 2.5 V, or 1.8 V and all input pins

are 3.3-V, 2.5-V, and 1.8-V tolerant, allowing MAX 7000B devices to be

used in mixed-voltage systems.

MAX 7000B devices are supported by Altera development systems, which

are integrated packages that offer schematic, text—including VHDL,

Verilog HDL, and the Altera Hardware Description Language (AHDL)—

and waveform design entry, compilation and logic synthesis, simulation

and timing analysis, and device programming. Altera software provides

EDIF 2 0 0 and 3 0 0, LPM, VHDL, Verilog HDL, and other interfaces for

additional design entry and simulation support from other industry-

standard PC- and UNIX-workstation-based EDA tools. Altera software

runs on Windows-based PCs, as well as Sun SPARCstation, and HP 9000

Series 700/800 workstations.

Logic Array Blocks

The MAX 7000B device architecture is based on the linking of

high-performance LABs. LABs consist of 16 macrocell arrays, as shown in

Figure 1. Multiple LABs are linked together via the PIA, a global bus that

is fed by all dedicated input pins, I/O pins, and macrocells.

Each LAB is fed by the following signals:

■

36 signals from the PIA that are used for general logic inputs

Global controls that are used for secondary register functions

Direct input paths from I/O pins to the registers that are used for fast

setup times

Altera Corporation

Macrocells

The MAX 7000B macrocell can be individually configured for either

sequential or combinatorial logic operation. The macrocell consists of

three functional blocks: the logic array, the product-term select matrix,

and the programmable register. Figure 2 shows the MAX 7000B

macrocell.

Product Terms

Combinatorial logic is implemented in the logic array, which provides

five product terms per macrocell. The product-term select matrix allocates

these product terms for use as either primary logic inputs (to the ORand

XORgates) to implement combinatorial functions, or as secondary inputs

to the macrocell’s register preset, clock, and clock enable control

functions.

Two kinds of expander product terms (“expanders”) are available to

supplement macrocell logic resources:

■

Shareable expanders, which are inverted product terms that are fed

back into the logic array

Parallel expanders, which are product terms borrowed from adjacent

macrocells

Altera Corporation

7

MAX 7000B Programmable Logic Device Data Sheet

The Altera development system automatically optimizes product-term

allocation according to the logic requirements of the design.

For registered functions, each macrocell flipflop can be individually

programmed to implement D, T, JK, or SR operation with programmable

clock control. The flipflop can be bypassed for combinatorial operation.

During design entry, the designer specifies the desired flipflop type; the

MAX+PLUS II software then selects the most efficient flipflop operation

for each registered function to optimize resource utilization.

Each programmable register can be clocked in three different modes:

■

Global clock signal. This mode achieves the fastest clock-to-output

performance.

Global clock signal enabled by an active-high clock enable. A clock

enable is generated by a product term. This mode provides an enable

on each flipflop while still achieving the fast clock-to-output

performance of the global clock.

■

Array clock implemented with a product term. In this mode, the

flipflop can be clocked by signals from buried macrocells or I/O pins.

Two global clock signals are available in MAX 7000B devices. As shown

in Figure 1, these global clock signals can be the true or the complement of

either of the global clock pins, GCLK1or GCLK2.

Each register also supports asynchronous preset and clear functions. As

shown in Figure 2, the product-term select matrix allocates product terms

to control these operations. Although the product-term-driven preset and

clear from the register are active high, active-low control can be obtained

by inverting the signal within the logic array. In addition, each register

clear function can be individually driven by the active-low dedicated

global clear pin (GCLRn). Upon power-up, each register in a MAX 7000B

device may be set to either a high or low state. This power-up state is

specified at design entry.

All MAX 7000B I/O pins have a fast input path to a macrocell register.

This dedicated path allows a signal to bypass the PIA and combinatorial

logic and be clocked to an input D flipflop with an extremely fast input

setup time. The input path from the I/O pin to the register has a

programmable delay element that can be selected to either guarantee zero

hold time or to get the fastest possible set-up time (as fast as 1.0 ns).

Altera Corporation

MAX 7000B Programmable Logic Device Data Sheet

Expander Product Terms

Although most logic functions can be implemented with the five product

terms available in each macrocell, more complex logic functions require

additional product terms. Another macrocell can be used to supply the

required logic resources. However, the MAX 7000B architecture also

offers both shareable and parallel expander product terms (“expanders”)

that provide additional product terms directly to any macrocell in the

same LAB. These expanders help ensure that logic is synthesized with the

fewest possible logic resources to obtain the fastest possible speed.

Shareable Expanders

Each LAB has 16 shareable expanders that can be viewed as a pool of

uncommitted single product terms (one from each macrocell) with

inverted outputs that feed back into the logic array. Each shareable

expander can be used and shared by any or all macrocells in the LAB to

build complex logic functions. A small delay (t_SEXP) is incurred when

shareable expanders are used. Figure 3 shows how shareable expanders

can feed multiple macrocells.

Figure 3. MAX 7000B Shareable Expanders

Shareable expanders can be shared by any or all macrocells in an LAB.

MAX 7000B Programmable Logic Device Data Sheet

Parallel Expanders

Parallel expanders are unused product terms that can be allocated to a

neighboring macrocell to implement fast, complex logic functions.

Parallel expanders allow up to 20 product terms to directly feed the

macrocell ORlogic, with five product terms provided by the macrocell and

15 parallel expanders provided by neighboring macrocells in the LAB.

The Altera Compiler can automatically allocate up to three sets of up to

five parallel expanders to the macrocells that require additional product

terms. Each set of five parallel expanders incurs a small, incremental

timing delay (t_PEXP). For example, if a macrocell requires 14 product

terms, the Compiler uses the five dedicated product terms within the

macrocell and allocates two sets of parallel expanders; the first set

includes five product terms and the second set includes four product

terms, increasing the total delay by 2 × t_PEXP

.

Two groups of eight macrocells within each LAB (e.g., macrocells 1

through 8, and 9 through 16) form two chains to lend or borrow parallel

expanders. A macrocell borrows parallel expanders from lower-

numbered macrocells. For example, macrocell 8 can borrow parallel

expanders from macrocell 7, from macrocells 7 and 6, or from macrocells

7, 6, and 5. Within each group of eight, the lowest-numbered macrocell

can only lend parallel expanders and the highest-numbered macrocell can

only borrow them. Figure 4 shows how parallel expanders can be

borrowed from a neighboring macrocell.

Programmable Interconnect Array

Logic is routed between LABs on the PIA. This global bus is a

programmable path that connects any signal source to any destination on

the device. All MAX 7000B dedicated inputs, I/O pins, and macrocell

outputs feed the PIA, which makes the signals available throughout the

entire device. Only the signals required by each LAB are actually routed

from the PIA into the LAB. Figure 5 shows how the PIA signals are routed

into the LAB. An EEPROM cell controls one input to a two-input ANDgate,

which selects a PIA signal to drive into the LAB.

PIA Signals

While the routing delays of channel-based routing schemes in masked or

field-programmable gate arrays (FPGAs) are cumulative, variable, and

path-dependent, the MAX 7000B PIA has a predictable delay. The PIA

makes a design’s timing performance easy to predict.

I/O Control Blocks

The I/O control block allows each I/O pin to be individually configured

for input, output, or bidirectional operation. All I/O pins have a tri-state

buffer that is individually controlled by one of the global output enable

signals or directly connected to ground or V_CC. Figure 6 shows the I/O

control block for MAX 7000B devices. The I/O control block has

six or ten global output enable signals that are driven by the true or

complement of two output enable signals, a subset of the I/O pins, or a

subset of the I/O macrocells.

When the tri-state buffer control is connected to ground, the output is

tri-stated (high impedance) and the I/O pin can be used as a dedicated

input. When the tri-state buffer control is connected to V_CC, the output is

enabled.

The MAX 7000B architecture provides dual I/O feedback, in which

macrocell and pin feedbacks are independent. When an I/O pin is

configured as an input, the associated macrocell can be used for buried

logic.

MAX 7000B Programmable Logic Device Data Sheet

MAX 7000B devices support the SameFrame pin-out feature for

SameFrame

Pin-Outs

FineLine BGA and 0.8-mm Ultra FineLine BGA packages. The

SameFrame pin-out feature is the arrangement of balls on FineLine BGA

and 0.8-mm Ultra FineLine BGA packages such that the lower-ball-count

packages form a subset of the higher-ball-count packages. SameFrame

pin-outs provide the flexibility to migrate not only from device to device

within the same package, but also from one package to another. FineLine

BGA packages are compatible with other FineLine BGA packages, and

0.8-mm Ultra FineLine BGA packages are compatible with other 0.8-mm

Ultra FineLine BGA packages. A given printed circuit board (PCB) layout

can support multiple device density/package combinations. For example,

a single board layout can support a range of devices from an EPM7064B

device in a 100-pin FineLine BGA package to an EPM7512B device in a

256-pin FineLine BGA package.

The Altera software provides support to design PCBs with SameFrame

pin-out devices. Devices can be defined for present and future use. The

Altera software generates pin-outs describing how to layout a board to

take advantage of this migration (see Figure 7).

MAX 7000B Programmable Logic Device Data Sheet

MAX 7000B devices can be programmed in-system via an industry-

standard 4-pin IEEE Std. 1149.1 (JTAG) interface. ISP offers quick, efficient

iterations during design development and debugging cycles. The

MAX 7000B architecture internally generates the high programming

voltages required to program EEPROM cells, allowing in-system

programming with only a single 2.5-V power supply. During in-system

programming, the I/O pins are tri-stated and weakly pulled-up to

eliminate board conflicts. The pull-up value is nominally 50 k¾.

In-System

Programma-

bility (ISP)

MAX 7000B devices have an enhanced ISP algorithm for faster

programming. These devices also offer an ISP_Done bit that provides safe

operation when in-system programming is interrupted. This ISP_Done

bit, which is the last bit programmed, prevents all I/O pins from driving

until the bit is programmed.

ISP simplifies the manufacturing flow by allowing devices to be mounted

on a PCB with standard pick-and-place equipment before they are

programmed. MAX 7000B devices can be programmed by downloading

the information via in-circuit testers, embedded processors, the Altera

MasterBlaster communications cable, and the ByteBlasterMV parallel port

download cable. Programming the devices after they are placed on the

board eliminates lead damage on high-pin-count packages (e.g., QFP

packages) due to device handling. MAX 7000B devices can be

reprogrammed after a system has already shipped to the field. For

example, product upgrades can be performed in the field via software or

modem.

In-system programming can be accomplished with either an adaptive or

constant algorithm. An adaptive algorithm reads information from the

unit and adapts subsequent programming steps to achieve the fastest

possible programming time for that unit. A constant algorithm uses a

pre-defined (non-adaptive) programming sequence that does not take

advantage of adaptive algorithm programming time improvements.

Some in-circuit testers cannot program using an adaptive algorithm.

Therefore, a constant algorithm must be used. MAX 7000B devices can be

programmed with either an adaptive or constant (non-adaptive)

algorithm.

The Jam Standard Test and Programming Language (STAPL), JEDEC

standard JESD-71, can be used to program MAX 7000B devices with

in-circuit testers, PCs, or embedded processors.

For more information on using the Jam language, see Application Note 88

(Using the Jam Language for ISP & ICR via an Embedded Processor) and

Application Note 122 (Using STAPL for ISP & ICR via an Embedded Processor).

f

The ISP circuitry in MAX 7000B devices is compliant with the IEEE

Std. 1532 specification. The IEEE Std. 1532 is a standard developed to

allow concurrent ISP between multiple PLD vendors.

MAX 7000B Programmable Logic Device Data Sheet

Programming Sequence

During in-system programming, instructions, addresses, and data are

shifted into the MAX 7000B device through the TDIinput pin. Data is

shifted out through the TDOoutput pin and compared against the

expected data.

Programming a pattern into the device requires the following six ISP

stages. A stand-alone verification of a programmed pattern involves only

stages 1, 2, 5, and 6.

1. Enter ISP. The enter ISP stage ensures that the I/O pins transition

smoothly from user mode to ISP mode. The enter ISP stage requires

1 ms.

2. Check ID. Before any program or verify process, the silicon ID is

checked. The time required to read this silicon ID is relatively small

compared to the overall programming time.

3. Bulk Erase. Erasing the device in-system involves shifting in the

instructions to erase the device and applying one erase pulse of

100 ms.

4. Program. Programming the device in-system involves shifting in the

address and data and then applying the programming pulse to

program the EEPROM cells. This process is repeated for each

EEPROM address.

5. Verify. Verifying an Altera device in-system involves shifting in

addresses, applying the read pulse to verify the EEPROM cells, and

shifting out the data for comparison. This process is repeated for

each EEPROM address.

6. Exit ISP. An exit ISP stage ensures that the I/O pins transition

smoothly from ISP mode to user mode. The exit ISP stage requires

1 ms.

Programming Times

The time required to implement each of the six programming stages can

be broken into the following two elements:

■

A pulse time to erase, program, or read the EEPROM cells.

A shifting time based on the test clock (TCK) frequency and the

Altera Corporation

MAX 7000B Programmable Logic Device Data Sheet

By combining the pulse and shift times for each of the programming

stages, the program or verify time can be derived as a function of the TCK

frequency, the number of devices, and specific target device(s). Because

different ISP-capable devices have a different number of EEPROM cells,

both the total fixed and total variable times are unique for a single device.

Programming a Single MAX 7000B Device

The time required to program a single MAX 7000B device in-system can

be calculated from the following formula:

MAX 7000B devices can be programmed on Windows-based PCs with an

Altera Logic Programmer card, the Master Programming Unit (MPU),

and the appropriate device adapter. The MPU performs continuity

checking to ensure adequate electrical contact between the adapter and

the device.

Hardware

For more information, see the Altera Programming Hardware Data Sheet.

f

The Altera software can use text- or waveform-format test vectors created

with the Altera Text Editor or Waveform Editor to test the programmed

device. For added design verification, designers can perform functional

testing to compare the functional device behavior with the results of

simulation.

Data I/O, BP Microsystems, and other programming hardware

manufacturers provide programming support for Altera devices. For

more information, see Programming Hardware Manufacturers.

MAX 7000B devices include the JTAG boundary-scan test circuitry

defined by IEEE Std. 1149.1. Table 6 describes the JTAG instructions

supported by MAX 7000B devices. The pin-out tables starting on page 59

of this data sheet show the location of the JTAG control pins for each

device. If the JTAG interface is not required, the JTAG pins are available

as user I/O pins.

Table 6. MAX 7000B JTAG Instructions

JTAG Instruction

Description

SAMPLE/PRELOAD Allows a snapshot of signals at the device pins to be captured and examined during

normal device operation, and permits an initial data pattern output at the device pins.

EXTEST

Allows the external circuitry and board-level interconnections to be tested by forcing a

test pattern at the output pins and capturing test results at the input pins.

BYPASS

Places the 1-bit bypass register between the TDIand TDOpins, which allows the

boundary-scan test data to pass synchronously through a selected device to adjacent

devices during normal operation.

CLAMP

Allows the values in the boundary-scan register to determine pin states while placing the

1-bit bypass register between the TDIand TDOpins.

IDCODE

Selects the IDCODE register and places it between the TDIand TDOpins, allowing the

IDCODE to be serially shifted out of TDO.

USERCODE

ISP Instructions

Selects the 32-bit USERCODE register and places it between the TDIand TDOpins,

allowing the USERCODE value to be shifted out of TDO.

These instructions are used when programming MAX 7000B devices via the JTAG ports

with the MasterBlaster or ByteBlasterMV download cable, or using a Jam File (.jam),

Jam Byte-Code File (.jbc), or Serial Vector Format File (.svf) via an embedded

MAX 7000B Programmable Logic Device Data Sheet

MAX 7000B devices offer a power-saving mode that supports low-power

Programmable

Speed/Power

Control

operation across user-defined signal paths or the entire device. This

feature allows total power dissipation to be reduced by 50% or more,

because most logic applications require only a small fraction of all gates to

operate at maximum frequency.

The designer can program each individual macrocell in a MAX 7000B

device for either high-speed or low-power operation. As a result, speed-

critical paths in the design can run at high speed, while the remaining

paths can operate at reduced power. Macrocells that run at low power

incur a nominal timing delay adder (t_LPA) for the t_LAD, t_LAC, t_IC, t_ACL

t_CPPW, t_EN, and t_SEXPparameters.

,

MAX 7000B device outputs can be programmed to meet a variety of

system-level requirements.

Output

Configuration

MultiVolt I/O Interface

The MAX 7000B device architecture supports the MultiVolt I/O interface

feature, which allows MAX 7000B devices to connect to systems with

differing supply voltages. MAX 7000B devices in all packages can be set

for 3.3-V, 2.5-V, or 1.8-V pin operation. These devices have one set of V_CC

pins for internal operation and input buffers (VCCINT), and another set for

I/O output drivers (VCCIO).

The VCCIOpins can be connected to either a 3.3-V, 2.5-V, or 1.8-V power

supply, depending on the output requirements. When the VCCIOpins are

connected to a 1.8-V power supply, the output levels are compatible with

1.8-V systems. When the VCCIOpins are connected to a 2.5-V power

supply, the output levels are compatible with 2.5-V systems. When the

VCCIOpins are connected to a 3.3-V power supply, the output high is at

3.3 V and is therefore compatible with 3.3-V or 5.0-V systems. Devices

operating with V_CCIOlevels of 2.5 V or 1.8 V incur a nominal timing delay

adder.

Table 10 describes the MAX 7000B MultiVolt I/O support.

Open-Drain Output Option

MAX 7000B devices provide an optional open-drain (equivalent to

open-collector) output for each I/O pin. This open-drain output enables

the device to provide system-level control signals (e.g., interrupt and

write enable signals) that can be asserted by any of several devices. It can

also provide an additional wired-ORplane.

Programmable Ground Pins

Each unused I/O pin on MAX 7000B devices may be used as an additional

ground pin. This programmable ground feature does not require the use

of the associated macrocell; therefore, the buried macrocell is still

available for user logic.

Slew-Rate Control

The output buffer for each MAX 7000B I/O pin has an adjustable output

slew rate that can be configured for low-noise or high-speed performance.

A faster slew rate provides high-speed transitions for high-performance

systems. However, these fast transitions may introduce noise transients

into the system. A slow slew rate reduces system noise, but adds a

nominal delay of 4 to 5 ns. When the configuration cell is turned off, the

slew rate is set for low-noise performance. Each I/O pin has an individual

EEPROM bit that controls the slew rate, allowing designers to specify the

slew rate on a pin-by-pin basis. The slew rate control affects both the rising

and falling edges of the output signal.

Advanced I/O Standard Support

The MAX 7000B I/O pins support the following I/O standards: LVTTL,

LVCMOS, 1.8-V I/O, 2.5-V I/O, GTL+, SSTL-3 Class I and II, and SSTL-2

Class I and II.

Altera Corporation

23

MAX 7000B Programmable Logic Device Data Sheet

MAX 7000B devices contain two I/O banks. Both banks support all

standards. Each I/O bank has its own VCCIOpins. A single device can

support 1.8-V, 2.5-V, and 3.3-V interfaces; each bank can support a

different standard independently. Within a bank, any one of the

terminated standards can be supported.

Figure 9 shows the arrangement of the MAX 7000B I/O banks.

Each MAX 7000B device has two VREFpins. Each can be set to a separate

V_REFlevel. Any I/O pin that uses one of the voltage-referenced standards

(GTL+, SSTL-2, or SSTL-3) may use either of the two VREFpins. If these

pins are not required as VREFpins, they may be individually

programmed to function as user I/O pins.

Altera Corporation

MAX 7000B Programmable Logic Device Data Sheet

Programmable Pull-Up Resistor

Each MAX 7000B device I/O pin provides an optional programmable

pull-up resistor during user mode. When this feature is enabled for an I/O

pin, the pull-up resistor (typically 50 k¾) weakly holds the output to

V_CCIOlevel.

Bus Hold

Each MAX 7000B device I/O pin provides an optional bus-hold feature.

When this feature is enabled for an I/O pin, the bus-hold circuitry weakly

holds the signal at its last driven state. By holding the last driven state of

the pin until the next input signals is present, the bus-hold feature can

eliminate the need to add external pull-up or pull-down resistors to hold

a signal level when the bus is tri-stated. The bus-hold circuitry also pulls

undriven pins away from the input threshold voltage where noise can

cause unintended high-frequency switching. This feature can be selected

individually for each I/O pin. The bus-hold output will drive no higher

than V_CCIOto prevent overdriving signals. The propagation delays

through the input and output buffers in MAX 7000B devices are not

affected by whether the bus-hold feature is enabled or disabled.

The bus-hold circuitry weakly pulls the signal level to the last driven state

through a resistor with a nominal resistance (R_BH) of approximately

8.5 k¾. Table 12 gives specific sustaining current that will be driven

through this resistor and overdrive current that will identify the next

driven input level. This information is provided for each VCCIO voltage

level.

The bus-hold circuitry is active only during user operation. At power-up,

the bus-hold circuit initializes its initial hold value as V_CCapproaches the

recommended operation conditions. When transitioning from ISP to User

Mode with bus hold enabled, the bus-hold circuit captures the value

present on the pin at the end of programming.

MAX 7000B devices are compatible with PCI applications as well as all

MAX 7000B Programmable Logic Device Data Sheet

Because MAX 7000B devices can be used in a mixed-voltage environment,

they have been designed specifically to tolerate any possible power-up

sequence. The V_CCIOand V_CCINTpower planes can be powered in any

order.

Power

Sequencing &

Hot-Socketing

Signals can be driven into MAX 7000B devices before and during power-

up (and power-down) without damaging the device. Additionally,

MAX 7000B devices do not drive out during power-up. Once operating

conditions are reached, MAX 7000B devices operate as specified by the

user.

MAX 7000B device I/O pins will not source or sink more than 300 µA of

DC current during power-up. All pins can be driven up to 4.1 V during

hot-socketing.

All MAX 7000B devices contain a programmable security bit that controls

access to the data programmed into the device. When this bit is

programmed, a design implemented in the device cannot be copied or

retrieved. This feature provides a high level of design security, because

programmed data within EEPROM cells is invisible. The security bit that

controls this function, as well as all other programmed data, is reset only

when the device is reprogrammed.

Design Security

Generic Testing

MAX 7000B devices are fully functionally tested. Complete testing of each

programmable EEPROM bit and all internal logic elements ensures 100%

programming yield. AC test measurements are taken under conditions

equivalent to those shown in Figure 11. Test patterns can be used and then

erased during early stages of the production flow.

MAX 7000B device timing can be analyzed with the Altera software, with

a variety of popular industry-standard EDA simulators and timing

analyzers, or with the timing model shown in Figure 13. MAX 7000B

devices have predictable internal delays that enable the designer to

determine the worst-case timing of any design. The Altera software

provides timing simulation, point-to-point delay prediction, and detailed

timing analysis for device-wide performance evaluation.

The timing characteristics of any signal path can be derived from the

timing model and parameters of a particular device. External timing

parameters, which represent pin-to-pin timing delays, can be calculated

as the sum of internal parameters. Figure 14 shows the timing relationship

between internal and external delay parameters.

See Application Note 94 (Understanding MAX 7000 Timing) for more

information.

running in low-power mode.

Supply power (P) versus frequency (f_MAX, in MHz) for MAX 7000B

devices is calculated with the following equation:

Power

Consumption

P = P_INT+ P_IO= I_CCINT× V_CC+ P_IO

The P_IOvalue, which depends on the device output load characteristics

and switching frequency, can be calculated using the guidelines given in

Application Note 74 (Evaluating Power for Altera Devices).

The I_CCINTvalue depends on the switching frequency and the application

logic. The I_CCINTvalue is calculated with the following equation:

I_CCINT

=

(A × MC_TON) + [B × (MC_DEV– MC_TON)] + (C × MC_USED× f_MAX× tog_LC

)

The parameters in this equation are:

MC_TON

=

Number of macrocells with the Turbo Bit^TMoption turned

on, as reported in the MAX+PLUS II Report File (.rpt)

Number of macrocells in the device

Total number of macrocells in the design, as reported in

the Report File

MC_DEV

MC_USED

=

f_MAX

tog_LC

=

Highest clock frequency to the device

Average percentage of logic cells toggling at each clock

(typically 12.5%)

This calculation provides an I_CCestimate based on typical conditions

using a pattern of a 16-bit, loadable, enabled, up/down counter in each

LAB with no output load. Actual I_CCshould be verified during operation

because this measurement is sensitive to the actual pattern in the device

and the environmental operating conditions.
