It would appear both DC3 and DEL you are using as stimulus demonstrate a gtkwave bug, either of those values cause gtkwave to crash dump file types fst and ghw. It would appear gtkwave is using in band signalling for storing value strings for x. If you don't add x to the gtkwave waveform it won't crash. Does VCD support characters? If not, a use GHW which does, or convert from character to something integer?

Also, gtkwave didn't crash in my case. I understand work around approach, thank you. BrianDrummond Yes, you are right. Specify your VCD import options. Use the VCD Import Options window to specify the instance name of your design in the simulation testbench the instance name is the instance name of your design instantiated in the simulation testbench.

Even if the Import command succeeds, Actel recommends that you use SmartPower to verify which of the pins have been affected after you import the file. Verify results of the imported file in the Activity tab screen in SmartPower. Take our short survey. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
