settings for a predefined style, open
the Define Synthesis Style dialog
box, select the style in the Style box,
and choose the Use Default button.
logical operator An operator that
performs a logic operation on nodes,
groups, or numbers.
AHDL logical operators are NOT (!), AND
(&), NAND (!&), OR (#), NOR (!#), XOR ($),
and XNOR (!$).
VHDL logical operators are AND, NAND, OR,
NOR, XOR, and NOT.
Verilog HDL logical operators are and (&&)
and or (||).
LPM see Library of Parameterized
Modules.
LSB see least significant bit.
M
macrocell see logic cell.
macrofunction A high-level building block
that can be used together with gate and
flipflop primitives and/or megafunctions
in MAX+PLUS II design files.
1 In general, Altera recommends using
megafunctions in preference to
equivalent macrofunctions in all new
projects. Megafunctions are easier to
scale to different sizes and offer more
efficient logic synthesis and device
implementation.
Altera provides a library of over 300 old-
style macrofunctions in the \maxplus2\
max2lib directory and its subdirectories
created during installation. AHDL Include
Files (.inc) for these macrofunctions are
located in the \maxplus2\max2inc
directory; VHDL Component Declarations
for macrofunctions supported by VHDL
are provided in the maxplus2 package in
the altera library, which is located in a
subdirectory of the \maxplus2\vhdlnn
directory, where nn is Ò87Ó or Ò93Ó. On a
UNIX workstation, the maxplus2 directory
is a subdirectory of the /usr directory.
To view the file that contains the logic for a
macrofunction, select the macrofunction
symbol in the Graphic Editor or
macrofunction name in the Text Editor and
choose Hierarchy Down (File menu).
MAX 5000 An Altera device family based
on the first generation of Multiple Array
MatriX architecture. This EPROM-based
device family includes the EPM5032,
EPM5064, EPM5128, EPM5128A,
EPM5130, and EPM5192 devices.
MAX 7000, MAX 7000E, and MAX 7000S
An Altera device family based on the
second generation of Multiple Array
MatriX architecture that includes
MAX 7000, MAX 7000E, and MAX 7000S
devices. These EEPROM-based devices
include EPM7032, EPM7032V, EPM7064,
EPM7064S, EPM7096, EPM7128E,
EPM7128S, EPM7160E, EPM7192E,
EPM7192S, EPM7256E, and EMP7256S
devices.
MAX 7000S and 7000E devices are
enhanced versions of MAX 7000 devices
and are function-, pin-, and programming-
file-compatible with MAX 7000 devices.
MAX 7000E and MAX 7000S devices differ
from MAX 7000 devices in that they offer
up to six pin- or logic-driven Output
