irun (ncsim) without waveform

sorel789

Hi,

 

I need to run a test without waveform. I'm using irun (ncsim). Code is written in systemverilog (OVM). Each time I run the test, the waves.shm dir is created with 2 files : 1 dsn and 1 trn. I don't need them, I just want to run without gui and without waveform.

 

my command : irun -v200x -ovm -incdir my_dir -nowarn PMBDVX +OVM_TESTNAME=test_name tb_top.sv rtl.vhd 

 

Thanks,

Parents

  • Hello,

    Thanks for your patience as we try to narrow where in the code the instruction for dumping waveforms is located.

    I noticed that you are using a -incdir to include various files out of the directory named my_dir.  Can you grep for "shm_" in all of the files of that directory (unix>  grep shm_  my_dir/*). 

    as another option try doing a decompile of the snapshot as follows:

    1)  find the name of the snapshot (ncls -snapshot)

    2)  decompile the snapshot (ncdc -origfiles <snapshot name>)

    3)  cd into the created ncdc directory and grep for shm_ in all of the files that were created.

    if the above doesn't work, let me know, I have some other ideas that may help.

    Best regards,

    Mickey
