Cary R	0eac9f8e9d	For VCD and FST dumpers only sort scope list when needed. We keep a scope list that is checked to verify that we do not try to dump duplicate scopes or variables. Since the scan_item routine can not add duplicate scopes we only need to sort the list after the scan_item routine is called. Calling it every time a scope was added was creating a significant startup delay for gate level simulations since the sort routine is called for every scope in the design (possibly thousands of times). This mostly matches what was done for the LXT dumper except the LXT dumper was incorrectly sorting before not after scan_item was called. This would not catch a duplicate variable just after a scope was added in a $dumpvars call.	2010-05-23 17:16:48 -07:00
Cary R	f11ba81202	Add initial fst support. This patch is a slight modification to files Tony Bybell (the author of GTKWave) send to me. We still have a few more changes we plan to make, but this should be functional enough for initial testing. Multi-treading and speed/size flags will be added shortly.	2010-05-21 17:26:44 -07:00

For VCD and FST dumpers only sort scope list when needed.

We keep a scope list that is checked to verify that we do not try
to dump duplicate scopes or variables. Since the scan_item routine
can not add duplicate scopes we only need to sort the list after
the scan_item routine is called. Calling it every time a scope
was added was creating a significant startup delay for gate level
simulations since the sort routine is called for every scope in
the design (possibly thousands of times).

This mostly matches what was done for the LXT dumper except the
LXT dumper was incorrectly sorting before not after scan_item
was called. This would not catch a duplicate variable just
after a scope was added in a $dumpvars call.
