MDL postprocessing of FSDB wave

dansIn

Hello,

Im thinking of using  MDL for comparing waves coming from Verilog to waves coming from spectre.

Let's say I have a fsdb wave from verilog AMS simulation and I'd like to apply to it a set of measurements such as max, cross etc...

and compare results to measurements I obtained from spectremdl run. So my question is:

Is it possible to use mdl config file for postprocessing FSDB wave without netlist? Smth like:

mdl -b cfg.mdl -r my_design.fsdb -out my_meas_dir

All examples in MDL_workshop are about specte/ultrasim  postprocessing when netlist is available.  In my case, I just have a file with wave that should be self-sufficient.

Tnx,

Dan

  • Tnx Andrew,

    so as far Im aware, cadence provides a way to convert vcd to psf and Springsoft has a utility that converts (digital only) fsdb to vcd.

    Seems like a deadend for analog  fsdb waves. I'll try to find a way to generate VCD waves though. If what you say is correct i.e. no netlist is needed and I can get all this rich MDL API to measure converted from VCD waves, it could be a workaround.

    tnx again,
