Thanks. So ... looks like that I need to simulate extracted schematics due to achieve this? I mean adding PD=.., PS=..., ... to output spice models
Didn't see such behavior at least when spice code is added to layout cell instead of schematics. May be I need to learn this magic HOWTO from manual ... So is the keypoint a simulation of extracted netlist? And back annotation of these parameters from layout to schematics could be a good idea as wheel, if come people annotate PD,PS and so on to schematic symbol of "custom transistor' in tanner tools. Not sure yet.
