how to avoid DRC violation in soc encounter when adding decap cells as fillers

[zhangljz]

Hello,

At the end of PR, I need to add fillers in the deisng, and I prefer decap cells because they are helpful to IR drop. But since decap cells has metal1 inside, when I chose decap cells for filler adding, all the gaps are filled with decap cells which leads to many DRC shorts. It seems that encounter is not DRC aware even though I checked "NO DRC" in add filler dialog.

How can I safely add decaps?

Hello,
Just check the value of this parameters.... setFillerMode -doDRC {true | false}.

This needs to be true to enable the DRC checking. It looks like that this is false in your case.
