Hi,

Make sure you have that .vwf.vht file in that path. The .vwf.vht file is auto-generated file and the generation path based on vwf file Simulation -> Simulation Settings -> Testbench Generation Command.

Also, may try to create a new vwf file to get the correct .vwf.vht file path.

Thanks,

Regards,

Sheng
