I have experienced a similar problem as this person where the tsabutfunction doesn't work well when the mosfet instance has a multiplier variable greater than 1. The PDK says this is a known issue, there recommendation is to use parallel mosfet's instead. I'm working with 10 parallel mosfet and would rather not place all 10 on the schematic, plus I might change them depending on simulations after layout. I'm wondering if there is a better work around. I have tried to place mosfet's in the layout that haven't been binded to an instance, but I can't figure out how to abut them. Any suggestions?
Thanks!
