Check signal value in order to stop simulation

frogconsultant

Hi Everyone,

I am trying to optimize the simulation time but checking the value of an analog signal in the simulation.

I am wondering if there is already a block (veriloga) or a function under cadence which check the value of an analog signal (i.e. for example after 10 values with 1us apart under 5% of the final value) and stop when the condition is met.

Any articles, websites or veriloga model would be perfect.

Thanks in advance for your help,

Parents

  •  Hi Fabian,

    The solution I referred to is describing the new Simulation->MDL Control menu which allows you to reference an MDL script to run the simulation. It's important to use this:

    envSetVal("spectre.envOpts" "mdlSimExecName" 'string "/export/home/apps/MMSIM101_isr/tools/bin/spectremdl")

    If using IC614, because otherwise it doesn't work (this is fixed in IC615). Of course, alter the path as necessary.

    For more details on SpectreMDL, read the documentation on SpectreMDL (in the MMSIM documentation) which covers how to use autostop.

    Regards,

    Andrew.
