@andresmmera @Thomas Zecha in the PDK we have some tap devices which model substrate/well connection. The devices take 2 parematers

width

and

lanegth

. The problem is that the netlist entry for this kind of device should be something like this

XR1 1 2 ptap1 R=value

where value is calculated by a schematic editor based on a specific equation. Could we try to implement this with

muparser

?
