Section 6.3.2.1, page 67 (IEEE Std 1800™-2005)

Change

To support whether a constant is $, a system function is provided to test whether a constant is a $. The syntax

of the system function is

$isunbounded(const_expression);

$isunbounded returns true if const_expression is unbounded. Typically, $isunbounded would be used as

a condition in the generate statement.

To

A system function is provided to test whether a constant is a $. The syntax of the system function is

$isunbounded(constant_param_expression);

$isunbounded is of type bit and returns the value 1 (true) if constant_param_expression is the symbol $. A parameter can be assigned $ provided that the parameter is not involved in any expression. However, it can be used only wherever the symbol $ is allowed. Typically, $isunbounded(parameter) would be used as a condition in the generate statement.
