Well Tap, End Cap and Filler cells.

[ApTuPr]

Hello Folks

I am doing physical designing of ARM Core M0. I have two doubts:

1. Where to place special cells- End cap, well tap and Tie cells. May I know how and where to place them? Though I have theoretical idea but don't know after which step (floorplann, PnR, etc.) this should be done.

2. I am using Innovus, what is the command for placing these cells?

Hope to get reply soon

Thanks in advance
