giving user defined waveform as input

JagdishP

Hi,

I have captured waveform on oscilloscope in lab and I wish to give the exactly same shape voltage signal in simulator(virtuoso) 

I do have time-versus-voltage relationship of captured waveform, I could have used "vpwl" source from analogLib, but the problem with this source is  that, it gives me only 50points to define signal shape.

below is the waveform(actually zoomed in version) which i wish to use in simulation.

Can anyone please help me ?

    Put the time-value pairs in a file (one pair per line) and then use vpwlf rather than vpwl. Or use vsource with the type set to "pwl" and the option on the form to read from a file.

    Regards,

    Andrew.
