irun: Simulating an already generated snap-shot.

 Hi,

 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")?

Regards,

Abid.
