Hello,

I just found a strange pin within the schematic of an isolated low voltage "nmosi" transistor called "psub", what does it mean ? Where and what is that pin ?

Thanks for your help !

If its an isolated NMOS it must be sitting in its own 'psub' well. Perhaps by using DNWELL to isolate it ?

If so, this 'psub' needs to be tied off to some potential , so its connected to a PIN. You can star route this pin to your ground line or whatever you want your bulk connected to.

Yes, indeed. I found a solution, just erase that pin and connect the well where you find it most convenient electrically ! Works just fine !
