IUS 10.2 irun - how to re-run an already compiled snapshot

cubicle82

Under the old 3-step process (ncvlog+ncelab+ncsim), I could compile the testbench once.  Then call ncsim multiple times to run the sim again(without recompiling.)

How do I do that with irun? What are the proper command-line switches?

Parents

  • On the first invocation of irun, add -elaborate to the command line.  This will cause irun to perform compile and elaborate, creating a snapshot but not simulating.

     The snapshot can then be simulated by using the irun -R option (or -r <snapshot>) that I described previously.

     More detailed descrptions are availabe in the irun help: irun -helpall | grep "\-R"

     Hope that helps,
