Monte Carlo Simulations - Mismatch Analysis

AVen12

Hi,

 

I am using Cadence  6.1.5. I am trying to run Monte Carlo simulations with process and Mismatch variations in ADE XL.

When I run the simulation with only process variations, there seems to be no problem. However when I run the mismatch variations, I am getting the following message. 

 The netlist is up to date.

\o Time taken to compare the design with netlist:   0.0s

\o       ...successful.

\o compose simulator input file...

\e *Error* strcat: argument #2 should be either a string or a symbol (type template = "S") - nil

\e *Error* Error during netlisting of design for the point ID (4 1).

\e ("error" 1 t nil ("*Error* "))

\e 

\e 

\o 

\o *Error*   Error ID  = 5012

\o *Error*   Error Msg = Failed to create netlist.

When I go by the error message, "Failed to create netlist": I went to the concerned netlist directory and checked. There is a net list file there.Also when there is previously a message that net list has been created, I have no idea why it says that it failed to create a net list

Any help to solve this issue would be greatly appreciated. Thanks a lot! 

  • I'm not sure why this would happen (by the way, it's the input.scs which may be failing to be created, not necessarily the file "netlist"), or why it should be specific to "mismatch" (the netlist shouldn't really be any different in process or mismatch mode - it would affect the montecarlo analysis statement, but that's all).

    So we'll need to see your data (I can't see any reports of this from a very quick search). So please log a service request with customer support.

    Regards,

    Andrew.

  • It took some time for me to get the license details.Meanwhile I was meddling with the simulation set up and realised that I had missed a step to set up instances for mismatch and that was the problem.

    It is working fine now.

     Thank you.
