stb Ocean/Skill examples

dlbro

Does anyone have any examples of using the stability analysis (stb) Sprectre tool in Ocean/Skill? I've done extensive scripting in transient, AC, DC, noise, pnoise, etc... but this is the first time I've tried stb. Running stb is easy, I've seen some stuff on how to do phase margin and gain margin, but how do I plot the gain and the phase? I've searched Cadence and Source link and the internet to no avail. Is there any equivalent to VT(), VF(), VS() for stb?

Thanks in advance,

dlb

  • Yuanzy,

    There was a recent bug where the "add to outputs" had gone missing for stb analyses from the direct plot form in recent versions. I think that has been addressed now.

    However, I cannot comment on using this with HSPICE; you'd have to ask Synopsys that.

    Regards,

    Andrew.
