[SOLVED] How to perform a Line transient in Buck converter using cadence?

[AMSA84]

Hi guys,

The topic says everything. I would like to perform a input voltage step to see how my converter reacts.

How can I do this? I have tried using VPWL but without success. An error occured, saying that Time is not strictly increasing. Don't know why.

Regards.

Time is not strictly increasing.

Probably an error in your VPWL source timing. If you have more than one VPWL sources, their timing must be synchronized.

I usually stack vdc, vpulse sources. For the PWL source, check
the t0, t1, t2... timepoints in the vpwl property list and make
sure they are (as the error message complains) monotonically
increasing.

Thank you guys. It was as you said erikl.
