Making a System Call After Simulation

[Scott Brady Drummonds]

Hi, everyone,

I'm a Verilog novice and am trying to have my compiled circuit execute a PLI
routine after simulation is complete (to write out some data I've collected
during simulation). However, I have no idea how to do this. My stimulus is
provided in EVCD format, so it appears that just adding my call to that file
doesn't work.

How can I register my function to be called as simulation completes?

Thanks!
Scott

It is easy. Just register a cbEndOfSimulation call back. If
your simulator supports modern +load_vpi= option, easiest is to register
the call back in one of the [booststrap routine list] routines.
You can see an example that uses this callback in the vacbtst.c
program in the tests_and_examples directory of our gpl-cver
release (home: www.pragmatic-c.com/gpl-cver).

Steve,

After following your suggestion to some more resources, I found out that my
simulator--VCS--doesn't support cbEndOfSimulation. It does, however,
provide another mechanism (vcs_atexit(void (*)(int)) that provides a similar
function.

Thank you so much for the pointer. It got me on the right track!
