Hey all. I tried to do some RF S parameter simulation using nfet3_20v0.sym of sky130. It is giving an error of  "Could not find a valid modelname". Can anyone help with how do i start amplifier S parameter simulation?

Thanks

<@U07TGSQA1ED> Check that your devices size is supported by the binned spice models. See <https://open-source-silicon.slack.com/archives/C017P3RAD42/p1736275438078259?thread_ts=1736268845.823759&amp;cid=C017P3RAD42>

Thank Mr. <@U017X0NM2E7> I think it was too small.. It gives some results now.

<@U017X0NM2E7>, my bad. The problem was something else. Nonetheless, although it doesn't give this error now, I don't get any amplification yet. Still trying to see if I need matching etc.
