there are different cells placed at different stages. -Before power planning we have to put 3 things i.e. power switches, End cap cell and Tap Cells -Post PG insertion : Here we put level shifters, isolation and detention cells. - the above cells placed are also called pre-placement cells. -post routing optimization: filler cell(can also be put after placement), spare cell tie-up tie-down, - decap cells can be placed after power planning or during post routing as IR drop occurs more at routing stage. hope this answers your question :)
Small request from my side u do video on what are various issues comes in pnr ie from floorplan to routing and how to solve it in real-time. ICC2 tool reference
@@sanjusingertelugu9862 wish I could do videos with reference to ICC2, Presently I don't have an access to the tool but yes I will definitely make videos on analysis which includes issues and solutions after finishing the PD flow.
i have a doubt in which stage these cells are added?
