Export the result wave and use it in other simulations?

FormerMember

Hello everyone,

I'm wondering whether is it possible to use the result wave of one simulation in another simulation. As shown in the following figure, I have some waves, can I somehow use it as input of another simulation?

Thanks a lot for help!

Regards,

  • Dear Holz,

    Did you consider exporting the waves of interest to ASCII files and using the the files  in a piecewise linear source?

    i, personally, do not believe any of the Cadence output waveform binary formats can be used as part of a netlist as an input signal directly. Hence,   I think you need to re-format the waveforms into a source that spectre can use in a simulation.

    A second reason that you may not want to include waveforms directly is that the source resistance of your waveform will not be imported

     

    into the new simulation. If your waveform has a large output impedance, that will not appear in your simulation. Hence, using the waveform in a new simulation is probably not equivalent to having the load of your second simulation in the initial simulation. If you use a piecewise linear source with the ASCII data in your second simulation, you can include a source resistance representative of the actual waveform - which is a more accurate representation of how the signal  will appear on your second simulation.
