How do I export Spectre simulation results to a CSV file using the command line?

kitmonisit

I'm running a Spectre netlist through the Linux shell, e.g. 

$ spectre my_netlist.scs

After running this simulation, I want to access the simulation results database. My questions are:

  1. What lines should I add to my Spectre netlist so that the simulation results are automatically exported to a specified CSV file?
  2. What topics in cdnshelp can help me get started with accessing the database using scripts that can be called from the command line?

 

  • Spectre doesn't have a "CSV" output format directly. Of course, you could write a VerilogA model that monitors a node and then writes out the changes to a CSV file.

    As for writing scripts, you can either use the Spectre Measurement Description Language (in the MMSIM documentation) or OCEAN (in the IC documentation) which provide a batch way of accessing simulation results and post-processing (MDL normally runs during the simulation). There's also a Spectre Toolbox for Matlab (which is also in the documentation) which allows you to directly read simulation results into Matlab.

    Kind Regards,

    Andrew.

  • Andrew, do you have a simple example of a VerilogA model that can monitor a node to print out a CSV during a Spectre or Ultrasim simulation?

    Thanks,

    Aaron

  • Aaron,

    No, sorry. I'd offer to write one but I'm a bit pushed for time at the moment.

    Regards,

    Andrew.
