@ -89,6 +89,36 @@ There are some special symbols that in certain contexts have special
|
|||
meanings. As inputs to functors, the symbols "C<0>", "C<1>", "C<x>"
|
||||
and "C<z>" represent a constant driver of the given value.

SCOPE STATEMENTS:
|
||||
|
||||
|
||||
PARAMETER STATEMENTS:
|
||||
|
||||
Parameters are named constants within a scope. These parameters have a
|
||||
type and value, and also a label so that they can be referenced as VPI
|
||||
objects.
|
||||
|
||||
The syntax of a parameter is:
|
||||
|
||||
<label> .param <name>, <type>, <value>;
|
||||
|
||||
The <name> is a string that names the parameter. The name is placed in
|
||||
the current scope as a vpiParameter object. The <type> is one of the
|
||||
following:
|
||||
|
||||
real -- The parameter has a real value
|
||||
string -- The parameter has a string value
|
||||
[<msb>,<lsb>,<s>]
|
||||
-- The parameter is a vector, with specified
|
||||
indices. The <s> is s or u for signed or
|
||||
unsigned.
|
||||
|
||||
The value, then, is appropriate for the data type. For example:
|
||||
|
||||
P_123 .param "hello", string, "Hello, World.";
|
||||
|
||||
|
||||
FUNCTOR STATEMENTS:
|
||||
|
||||
A functor statement is a statement that uses the ``.functor''
