In a standard techfile provided by Cadence (as an example in cadence_inst/tools.lnx86/dfII/samples/ROD/rodPcells), i can sucessfully creat the mos devices as the pcells. But for some reasons, i need to add another speical layer (its shaper and position should be the same as either nwell in nmos or pwell in pmos) in my mos devices, my question
is how to modify this previous techfile (either mos.device or mos.il) to produce a new Pcell ?
Thanks in advance
- In my opinion the example is too complicated for a beginner to understand PCell coding.- The example comes with a bunch of SKILL utility function for which it is hard to understand what’s going on behind the scenes.I don’t want to try how this is meant to be used by Cadence because I don’t need it actually.You can try adding the following to the mos.il code.
