Just remembered that Richard Maciel also wrote an article on cosimulation between the OSCI SystemC simulator and GHDL. IIRC, altho the article only states IPC, he also used POSIX mechanisms.
Article can be found there: http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=4208939 or there: http://www.lsc.ic.unicamp.br/publications/maciel2007isvlsi.pdf Cheers, -Pascal On Wed, Oct 13, 2010 at 10:55 AM, Pascal Giard <[email protected]> wrote: > On Tue, Oct 12, 2010 at 11:36 AM, Mike Crowe <[email protected]> > wrote: >> After looking at some of the issues associated with a direct calls to >> object code, I've decided to take the approach of spawning an instance >> of the target application, then use the vpi interface to communicate >> with a shared memory or message queue.
