Parallel VHDL Simulation on IBM SP2 and SGI Origin 2000

In this paper, we present the results of simulation by running parallel VHDL simulation on typical MPP(Massively Parallel Processor) systems such as IBM SP2 and SGI Origin 2000. Parallel simulation uses the synchronous protocol and parallel program is implemented using MPl(Message Passing Interface) based on message passing model, so that it can run on any parallel programming environment which supports MPI, a standard communication library. And then GVT(Global Virtual Time) cαnputation for parallel simulation is based on the global broadcasting with MPI_Bcast(), which ia a standard function in MPI and piggybacking. Our benchmark exhibits that as the size of VHDL grows, the parallel simulation has a better performance compared with the sequential simulation. In addition, we also show the results of comparison between IBM SP2 and SGI Origin 2000 by applying the same application to those indirectly.
