Is it possible to determine the exit code of a simulation from VHPI ?

[lemmuh]

Can a test running with VHPI influence the exit code of the simulation run (nvc -r top) ?

Do you mean set the exit code, similar to the status argument to finish? Not at the moment, but vhpi_control could probably be extended to do that since it takes optional arguments.

I do the verification by only using the VHPI interface. Then in CI the exit code should show me if there where any errors.

Using vhpi_control with the exit_code as an argument would be fine.

@nickg Do you have a plan to implement this ?

Sorry I forgot about this. The vhpi_control idea above won't work because there's no way with VHPI to tell how many arguments were passed. Instead I modified vhpi_assert so it sets the exit code in the same way as VHDL assert. So vhpi_assert(vhpiError, "...") should set the exit code to 1.
