Abstract:We show that FGBB should be applied in an architecture-aware manner, following the shapes of architectural modules. The reason is that architectural functionality affects the BB needed through temperature and type of critical path. To prove this idea, we develop a model of threshold voltage variation and apply it to simulated batches of chips. We show that architecture-aware FGBB enables 35% of the chips to work at the highest frequency, compared to 18% with conventional FGBB, potentially increasing each chip's value by 50%. It also reduces the leakage of the chips by 40%, compared to 25% with conventional FGBB.
