PAL Functions Listings
Following are the programmable array logic listings of the
devices used on the TMC2063P7C evaluation board. These
listings are shown as ABEL_HDL source files. The follow-
ing brief tutorial refers only to terms used for programming
logic used on this board.
Sets
A set is a collection of signals and constants that are operated
on as one unit. Any operation applied to a set is applied to
each element in the set. For example, in U9,
count = [c3,c2,c1,c0]
Valid operations used in the TMC2063:
The Basic Elements Of A Source File
Module
The module statement names the module
and indicates the presence of any dummy
variables used.
Title
The title statement can be used to give a
title or description for the module.
Declarations
Declarations associate names with devices,
pins, nodes, constants, macros, and sets.
Equations
It is possible to use equations, state dia-
grams, or truth tables to describe logic
designs. All programmable devices use
equations.
End
The end statement terminates the module.
Comments begin with double quotation
marks, " ", and end with either another dou-
ble quotation mark or the end of line,
whichever comes first.
