6.3 VPI Debugging

We provide a few commands to help debugging connectivity and communication between prsim and the host Verilog simulator.

— Function: $prsim_confirm_connections

When this is called before any $to_prsim/$from_prsim connections are made, each connection will be verbosely confirmed in the output.

— Function: $prsim_verbose_transport arg

If arg is 1 (or non-zero), then every value that is transported between verilog and prsim will be verbosely reported.
