Post-Processing
Syntax:
$vcdplusevent(net_or_reg,"event_name", "<E|W|I><S|T|D>");
eVCD
You can use $dumpports or $lsi_dumports system tasks to
generate EVCD files. Using system tasks you can generate multiple
EVCD files for various module instances of the design.
Line Tracing
You can enable line tracing for the design using -debug_all or
-debug as a compile-time option. The -debug_all option greatly
degrades the simulation performance and therefore you should use
it only for debugging. You can also use -PP -line as compile-time
options, instead of -debug_all.
Delta Cycle
VCS supports delta dumping in VPD files for post-processing using
the $vcdplusdeltacycleon system task. Like other system tasks,
this task can either be used in the design or can be entered at the
CLI prompt. However, to enable delta cycle dumping,
$vcdplusdeltacycleon should be entered before entering the
$vcdpluson system task.
