Assura DRC error: Ratio >= 0.0004

Latch up problem

Hi, Dear Friends,

Assura DRC shows some error like this:

Ratio (RX TripleWell contact)/(NFET gate not over N3) >= 0.004.

This is an error related to Latch up. There are already guard ring added to the active components. What are some other method which will eliminate latch up?


Thanks a lot.

Adam

What process are you working on? Can you give us some of the error transcript so that people here can help you further.

Check if you need to enable some switch for tripple well. Sounds like an RFMOS, what about using something like RFDUMMY to not to count on such MOS while doing latch-up check.
