verdi fsdb
Hi, all
I use VCS to compile and simulate a few verry simple verilog files. Testbench calls the tasks below to dump fsdb file.
$fsdbDumpfile("dump.fsdb");
$fsdbDumpvars;
Then I run command to pop up verdi
verdi -2001 -autoalias -f run.f -top system -ssf dump.fsdb -nologo
The problem is that source files and fsdb can be imported but can not put any signal on nWave. When drag and put one signal on nWave, a wanning window addresses that it is unrecognized signal. It seems to be due to dumping fsdb file because I try to dump to VCD file then open it in nWave, then everything is ok.
Could u give some suggestions on this issue?
Many thanks for your attention.
