From a user point of view, <code>Pattern</code> method is a pattern description
|
|
language using all standard <SPAN CLASS="textit">Python</SPAN> facilities. Here follows the
|
|
description of the <code>Pattern</code> method.
|
|
<BR>
|
|
A pat format file can be divided in two parts : declaration and description
|
|
part.
|
|
<BR>
|
|
The declaration part is the list of inputs, outputs, internal signals and
|
|
registers. Inputs are to be forced to a certain value and all the others are
|
|
to be observed during simulation.
|
|
<BR>
|
|
The description part is a set of patterns, where each pattern defines the value
|
|
of inputs and outputs. The pattern number represents actually the absolute time
|
|
for the simulator.
|
|
<BR>
|
|
Similarly, a <code>Pattern</code> method can be divided in two parts : declaration
|
|
and description part. Methods related to the declaration must be called
|
|
before any function related to the description part.
