Different simulation results for local and distributed host mode

 First thing to check is whether the netlist (the input.scs) is identical between the two different runs. In the vast majority of cases I've seen, differences in behaviour between different simulation runs can be explained by the fact that the netlists are not identical for some reason.

The other thing to remember is that normally local jobs are run in spectre's "interactive" mode. This has a tendency to mean that if you run a simulation twice, the simulator doesn't exit between runs and so the next solution starts from the previous solution. If you have a circuit with multiple stable operating points, there's no guarantee that the results will be the same. Also if the results only differ by numerical tolerances.

You can prevent "interactive" mode by using:

envSetVal("spectre.envOpts" "controlMode" 'string "batch")

before starting ADE. If you are still seeing a difference, there's a mild chance that differences in the OS could cause small differences, but that seems unlikely to me. The most likely is some difference in the netlist.

If after exploring this you still can't find the difference, please contact customer support.

Kind Regards,

Andrew.
