I took a look at the floorplan of one block i have, found that there are quite a lot of so call TAP cells been placed. could anybody explain to me what are tap cell and the usage of them?
Kumar - one clarification - Dont the standard cells themselves contain the substrate and bulk connections ???? Or are these connections excluded from the cells ??
@vinayshivakumar,
Std cell doesn't contains these TAP connections. Actually you don't need to use TAP connection in all the cells. It will increase the cell area & as well as chip area. Normally we place a TAP cell for around 5 or more std cells combined while doing top level routing
@forkschgrad,
I don't have any documents regarding this. The above answer is from my real experience.
