Compiler Directives and System Tasks
$reset_count
Keeps track of the number of times VCS executes the $reset
system task in a simulation session. See IEEE std 1364-2001
pages 741-742.
$reset_value
System function that you can use to pass a value from before to
after VCS executes the $reset system task, that is, you can
enter a reset_value integer argument to the $reset system
task, and after VCS resets the simulation the $reset_value
system function returns this integer argument. See IEEE std 1364-
2001 pages 741-742.
