Hi all,
I'm new to Cadence Virtuoso. Please help me with the different layers used and why they are used in virtuoso.
In the below attached screenshot(it's for inverter, but not completed yet) I have got 2 doubts, namely
1. For both PMOS(top) & NMOS, why PIMP/NIMP is kept around poly?
2. For NMOS, why the PWdummy(p-well, I think so) layer is used?
I'm familiar with Synopsis custom designer, but new to virtuoso.
Thanks in advance.
