I have the following darkriscv running on EDA playground with ICARUS,text however if I switch to VCS I get:

reset (startup)
Execution interrupted or reached maximum runtime.
Exit code expected: 0, received: 137

Any help or advise on this issue is greatly appreciated.

Thanks,

In the design file, at the bottom I have changed the simulator to VCS, but still get the same error.

I at least expect it to finish simulating.
