$fflushall system task. Syntax:
$fflushall;
$gr_waves
Produces a Value-Change-Dump file with the name grw.dump. In
this system task you can specify a display label for a net or register
whose transition times and values VCS records in the VCD file.
Syntax:
$gr_waves(["label",]net_or_reg,...);
Code example:
$gr_waves("wire w1",w1, "reg r1",r1);
LSI Certification VCD and EVCD Files
$lsi_dumpports
For LSI certification of your design, specifies recording a
simulation history file that contains the transition times and values
of the ports in a module instance.
This simulation history file for LSI certification contains more
information than the VCD file specified by the $dumpvars system
task. The information in this file includes strength levels and
whether the test fixture module (test bench) or the Device Under
Test (the specified module instance or DUT) is driving a signal’s
value.
Syntax:
$lsi_dumpports(module_instance,"filename");
Code example:
$lsi_dumpports(top.middle1,"dumports.dmp");
If you would rather have the $lsi_dumpports system task
