Look in the netlist directory for a file called runSimulation.  Do you
get different results if you run runSimulation?

Thanks Erik.

If I simulate via ADE the simulation completes and I get reasonable
looking output.

If I use Simulation -> Netlist -> Recreate and save the resulting
netlist to file and try to simulate it with >spectre my_netlist.scs,
Spectre immediately finds fatal errors (models complaining about
divide by zero).

Now if I use runSimulation I will get identical output to that when I
run in ADE until spectre reports that it is entering remote command
mode, at which point spectre has another error.

So this leads me to believe that one of the command line options in
runSimulation is causing a different execution.  My run simulation
contains the command:
spectre -env artist4.4.6 +log ../psf/spectre.out +inter=mpsc
+mpssession=spectre0_280 -format psfbin -raw ../psf input.scs

Now I've issolated these options and I'll always get that divide by
zero error unless I'm using the interactive options.

It's a bit disturbing that the batch mode result is different than the
interactive mode result.

Any explanation or other things I should try?

Thanks,

Michael

That's exactly right Erik.  If I run:
spectre -env artist4.4.6 +log ../psf/spectre.out -format psfbin -raw
../psf input.scs

I'll get fatal errors where the model complains about divide by zero.
If I simulate in ADE no errors are produced and I get a reasonable
simulation result.
