How can we know YOUR design and what do YOU have in mind?
Just list out the variables for which you want to monitor the sw. activity with the $dumpvars() command.
$dumpvars(level, list_of_variables_or_modules)
This task is used to specify which variables should be dumped. Both parameters are optional and if none are used, then all variables will be dumped.
If level = 0, then all variables within the modules from the list will be dumped. If any module from the list contains module instances, then all variables from these modules will also be dumped.
If level = 1, then only listed variables and variables of listed modules will be dumped.
