Optional Tracing #26

Open HU90m opened 6 months ago

HU90m commented 6 months ago

I made these changes for the sonata system and thought they may be valuable upstream.

I've changes ibexc_top_tracing module to match ports and parameters of ibexc_top. I've also made it possible to leave RVFI unset, in which case ibexc_top_tracing is equivalent to ibexc_top.

This allows users to use ibexc_top_tracing as a drop in replacement for ibexc_top, with the tracing only enabled when RVFI is enabled so that the same system top can be used for simulation and synthesis.

Can we not change top-level ports for ibexc_top_tracing? I am trying to make it consistent with ibex_top_tracing. and it breaks my environment and cheriot-safe environment as well
