logic cells, and multiple global Clocks with 
optional inversion. MAX 7000S devices 
also offer the additional capability of in-
system programming via JTAG boundary-
scan test circuitry.
1 Altera strongly recommends using 
MAX 7000S and MAX 7000E devices 
rather than equivalent MAX 7000 
devices for new designs.
MAX 9000 An Altera device family based 
on the third generation of Multiple Array 
MatriX architecture. These EEPROM-based 
devices include the EPM9560, EPM9560A, 
EPM9480, EPM9400, EPM9320, and 
EPM9320A devices.
MAX 9000A devices are enhanced versions 
of MAX 9000 devices, and are function-, 
pin-, and programming-file-compatible 
with MAX 9000 devices. MAX 9000A 
devices differ from MAX 9000 devices in 
that they offer an additional 16 bits for a 
user code.
MAX 9000 devices with the speed grade 
suffix ÒFÓ contain fixed programming 
algorithms, and therefore can be 
programmed with Serial Vector Format 
Files.
MAX+PLUS (DOS) AlteraÕs DOS-based 
Multiple Array MatriX Programmable 
Logic User System. MAX+PLUS is a set of 
computer programs and hardware support 
products for designing and implementing 
custom logic circuits with Altera Classic 
and MAX 5000 devices. Graphic Design 
Files (.gdf) created for MAX+PLUS are 
automatically converted and processed 
with the MAX+PLUS II Compiler; AHDL 
Text Design Files (.tdf) are compiled 
directly. The MAX+PLUS II Programmer 
can program Classic and MAX 5000 
devices with JEDEC Files (.jed) and 
Programmer Object Files (.pof) created by 
MAX+PLUS.
1 MAX+PLUS is no longer offered by 
Altera. All new designs should be 
created with MAX+PLUS II.
MAX+PLUS II Message File (.mmf) A 
binary file (with the extension .mmf) 
created by MAX+PLUS II that contains 
messages issued by any MAX+PLUS II 
application or command that runs as a 
background process, e.g., the Compiler 
and Programmer. This file is used to 
display messages in the Message Processor 
and to locate messages in design and 
ancillary files.
maxplus2.idx file A text file, created 
automatically when you save a file, that 
maps filenames with more than eight 
characters to 8-character filenames. 
MAX+PLUS II creates a maxplus2.idx file 
in each directory where you save a file that 
contains filenames with more than eight 
characters. The file is automatically 
updated each time you save a file with a 
long filename.
maxplus2.ini file A text file, created 
during installation, that contains the 
parameters that affect the way 
MAX+PLUS II applications operate. This 
file continuously records the options that 
you set in one session, so that they are 
automatically set for the next session. 
MegaCore and OpenCore megafunctions
MegaCore and OpenCore megafunctions 
are pre-verified HDL design files for 
complex system-level functions that can be 
purchased from Altera. These pre-tested 
megafunctions are optimized for
