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?

  • Hi Tim,

    I am also thinking about this one-step/multi-step irun flow.

     With one-step irun -nclibdirname $SNAPSHOT_DIR ... , my simulation works well and can be run anywhere. But later when I migrate this command into EManager, looks some of my cases terminated without running at all.

    I think it is probably related to this one-step command may not work well in EManager with parallel simulation at the same time.

    If I divide the irun by irun -c & irun -r , some questions below:

    1. first invocation of irun with "-c" option, do I need to supply case name "+UVM_TESTNAME=$testname" ?

    2, the second time when I want to sim only, what option is needed? Is it irun -R or irun -r ?

    3. how to merge ifv commands into irun ?

     

    I am now trying . if you can give some help meanwhile, very appreciated.
