I want to generate a snap-shot with name house and simulate it later.
To generate snap-shot, I use the following command,
irun -elaborate -snapshot house source.sv
This results in a folder INCA_libs/house.lnx86.11.10.nc
To simulate the snap-shot house, I use the following command,
irun -r worklib.house:sv
I get an error stating that the folder INCA_libs/irun.lnx86.11.10.nc is missing.
I see that even though I use the -r option with irun, it does not use the snap-shot house.
I also tried the -R option, but even with that I get the same error.
I see that if snap-shot name is chosen as "irun", this error is not seen.
How do I make irun simulate the snap-shot house (snap-shot name other than "irun")?
I tried it using Incisive 12.20, not 11.10.
irun -r house
irun: *N,NOSNPR: The default work directory (./INCA_libs/irun.lnx86.12.20.nc) is missing. -r house was used and a matching -snapshot house scratch directory was found. irun will imply the option -snapshot house.Loading snapshot worklib.house:sv .................... Donencsim> source /p/icom/eda/cadence/incisive/12.20.002/tools/inca/files/ncsimrcncsim> runncsim: *W,RNQUIE: Simulation is complete.
That is, I got a NOTE from irun, not an error. It still ran.
If I run it like this:
irun -r house -snapshot house
I did not get even the note.
In reply to Shalom B:
Even with 11.10, irun -r house -snapshot house gives the correct output.
Earlier, I used irun -r house which gave error. On adding, the -snapshot option, the error goes aways.
But when we look at the output of irun -helpall, we see that -snapshot option is used to generate a snapshot. And in this case, we do not want to generate a snapshot, but want to simulate an already existing snapshot. So I am not sure if using -snapshot option in this case is correct.
In reply to Abid:
The answer is in the documentation.
In the irun User Guide, it says,
Note: If you run irun with the -snapshot option (or its alias -name) to specify a name forthe simulation snapshot, you must include the original -snapshot option when you invoke
the simulation snapshot, you must include the original -snapshot option when you invoke
irun with irun -r snapshot_name.
-helpall just gives you a one-line description, not all the information.
That answers my question.
Thanks for your help Shalom.
