IC5.0 error when simulating pss

IC50 pss anaysis problem

I encountered something strange and I hope someone can help me here.

I just installed ic5.0 in redhat 8. Everything works fine until I try simulating pss. I always get the following error, even for a very simple circuit which is run properly on IC50 installed on Solaris:


Internal error found in spectre during periodic steady state analysis `pss'.
Please run `getSpectreFiles' or send the netlist, the spectre log file,
the behavioral model files, and any other information that can help
identify the problem to support@cadence.com.
Assertion failed in file `hopss.c' at line 1313.
Assertion failed.


I guess it may be casued some Envirument Variable whichs is not set properly or maybe I need a OS patch for IC50 to run properly on RH80.

any one can run PSS analysis properly on RH7.3 or RH7.2?

I had the similar problem but not sure whether the exact one as yours. However, I found out that spectreRF is not supported under ic50. You have to upgrade to either ic5032 or ic5033.

I also encounted it in unix.
Because we have many server, I will change other server when I had this problem.

Cadence IC5 only support RadHat 7.2, forget all other versions.

7.3 and 8.0 is also successful! Not only support 7.2!

But using Red Hat needs a little bit of tweaking here and there

IC50 can be installed under redhat7.2,redhat7.3&redhat8.0,but redhat9.0 can not be supported!

Pengboy,
Maybe firstly, you should check a file in ~/simulation/<cellviewname>/spectre/schematic/psf
directory, but I forgot the file name, whether the file is larger than 2,000MB.

If it does be true, you should appoint a swapfile in the pss setting window->option
