Re: Extracting device Vgb,Vsb,Vdb info from 'tranOp ??

npamd

Hi all, 

Couple of questions:

1. What I am trying to do is extract Vgb,Vdb,Vsb info for all devices in my design at the end of a transient.

It seems like 'tranOp has   info on (Vgs,Vds,Vgd,Vt) etc.  so I am easily able to write them out to a txt file through report command by doing something like this:

report(?output outPort ?param '("vgs" "vds" "vth" "vgd" ) ?format 'spice ?maxLineWidth 1000)
t

However, it seems to miss bulk-referenced voltages. Any way to capture this info ?

2. If I want to iterate through every FET in my design and capture its (g,d,s,b) voltages, and maybe try to find the absolute max a device sees on its Vdb,Vgb etc. throughout the duration of a transient sim, can that be done via a SKILL code ? 

Can someone please help me with this ?
