Hi @Tim Edwards is there a method to generate a guarding on p-substrate/n-well separately included in MAGIC or i should do it manually! Thanks

Devices 1 --> nwell region with guard ring
will draw a complete nwell guard ring, and
Devices 1 --> deep nwell region
will do the same. I really ought to have a similar method for substrate guard rings; instead, I have
Devices 1 --> substrate contact
(1.8V and 3.3V versions). The reason they don't draw rings is because often you just want to drop a substrate contact down near a circuit, not necessarily a ring. If you want to make a ring, draw a substrate contact four times (or write an additional generator for complete substrate rings).

Thanks @Tim Edwards I got it.
