My simvision version is 9.20-s017. I am trying to open schematic dumped by NCVerilog(version 8.20-S019), but I am not able to do it. Is it because simvision and NCVerilog versions are different? I am able to view the waves. I do not have older version of simvision or newer version of NCVerilog. Is there a way with which I can open the schematic with my current tool versions.
The waveform database is (relatively) stable and as you've seen can sometimes be read across versions. However, the design snapshot is very much version dependent and the 9.2 simvision cannot open an 8.2 snapshot. So it simply won't work.
