Simulations never proceed over "generate netlist..." in monte carlo

Hello everyone,

 I am attempting to run monte carlo on a design. The issue is, I can set everything up to distribute to 10 jobs, use APS, and other high performance options, but all of the job logs stagnate at "generate netlist...".

 If I open ADE and go: simulation -> netlist -> create, it is almost instant.

 The design may be rather large (I am not sure...) at around 3k transistors. The issue being, I wouldn't mind if it took a long time to run, but the simulation never leaves it's "preparing" state. It stays at: "running 0/x". I have given it 24 hours to start.

 Has anyone encountered this before? Liscensing is not an issue.

 

Thanks!

     Hey Andrew,

     Version:  IC6.1.5-64b.500.9

     Spectre sub-version: 11.1.0.487.isr13

    Last few lines of the job log look something like:
    \o Resetting statistical vars
    \o
    \o *Info*    Setting parameter values ...
    \o
    \o Setting var Vds = "0"
    \o Loading monte.cxt
    \o Setting var sigma = "0"
    \o Setting temp(T) = 27
    \o
    \o *Info*    Netlist Directory =
    \o          /dir/
    \o
    \o
    \o *Info*    Data Directory    =
    \o           /dir/
    \o
    \o
    \o *Info*    Creating Netlist for Point ID (4 1)
    \o
    \o generate netlist...

     

    There are no warnings or errors above these lines and nothing comes after generate netlist. Non Monte Carlo runs run ok. Also, I was able to get a Monte Carlo run to work and then subsequently tried another run with the exact same settings and it is giving the same issue with the generate netlist and job status freezing at "preparing".  I don't know if that information helps the situation or makes it more confusing.

     Thanks!
