I would like to discuss an old topic here, since that one is not allowed to submit new post.
From this thread: https://www.edaboard.com/showthread.php?t=359538&highlight=deep+nwell
at the 8th floor, the auther mentioned that the example layout, which short the n and p guard ring. My question is why they don't care about latch-up.
From experience, the p-guard ring nearby the nmos should be short to gnd, and the n-guard ring nearby the pmos should be short to vdd to prevent latch-up.
Thanks.
