The main purpose of integrating spare cells is for a cheaper fixing possibility without redoing ALL the masks. thanks for highlighting this.

With spares, you can get away with redoing a the masks for a few metal layers. without these cells, you'd have to recreate the entire mask set (including the expensive base layers). on separate note, muxes are a versatile choice for spare cells too. you havent stated this so… the issue with ASICs is an ECO after the masks are made (respins) is very expensive without spare cells.
