Yes can you share it Pls. I tried it but I got weird plots like this.

Please find attached. We observed some unexpected "kinks" for some devices for which investigations are still on-going (you will see the thread on this in the SKY slack channel)

Sky130 is worse in this condition, thats why I switched to gf180

what do you mean by "worse"? Modelling or gm/id values?

modelling especially svt and some gmid values

by "modelling" do you mean the "kink" which we have observed or have you observed some other peculiarities? What gmid values in particular? Context of my questions is I am concerned about gmid modelling in the process but only about the observed "kink". If you have seen any other strange behavior it would be great to know. Txs

Vt variation is very bad in svt, It was a headache to design stuff in svt

Interesting. Im currently characterising the vth spreads and am seeing some very large ranges also. I should be done with the full char by this week or next so will upload my results and ping you to see if they correlate with what you have seen / concluded

Sure lets see how bad it is

This is what I got. Apart from the lvt devices, spreads look pretty reasonable.

In one of my project I observed vth of svt nfet going as high 0.8V. I have forgotten the exact W, L

Interesting. If you are able to re-create the svt nfet 0.8V case please let me know the dimensions. I don't do any work however with GF180 so cant comment on its pfet3v3.

Sure
