Analog CMOS IC layout: DRC, DFM, DFR.
May 22nd, 2020, 7:53am
Regarding CMOS analog IC layout, what are differences between DRC, DFM and DFR?

What I understood during research:
- DRC (Design Rule Check)
checks if a laid out block follows technology rules what ensures dimensional precision and electrical parameters

- DFM (Design For Manufacturing)
additional check on top of DRC. Additional rigorous rules to further increase yield comparing to DRC.

Depending on technology, particular check rules may be included in DRC or DFM, e.g.: antenna effect check may be in DRC or DFM of a given technology in a given foundry.

Is, what I wrote above, correct?

What is DFR (Design For Reliability)? Is that just synonym of DFM?
