Is it possible to connect two workspace/simulations via DPI-C?

mxlusereight

I have two projects, both are very large and are the two sides of a serial transceiver, each has billions of gates.

The two projects simulate in the respective databases so merging database is not possible. The two projects have conflicting some submodules which are of different versions, so the module names and library names are the same but interface differ slightly. Thus calling the two DUT in the same TB won't work in the conventional xcellium sim flow.

Would it be possible/practical to connect the serial interface of the two projects together via DPI-C and run two simulation in a system? 

Are there any other proven means I can use to achieve that goal? Would MSIE get rid of the issue of conflicting module/library names? 

Thank you in advance. 

  • Xcelium has the Mutli-Snapshot Incremental Elaboration flow to support flows where IPs use conflicting library cell versions - this is primarily intended for supporting multi-die simulations.

    There is no way to connect to separate simulation processes, the synchronisation overhead and complexity would be very significant.
