MIA-aware FinFlex Cell Legalization with Power-Driven Cell Version Substitution
DescriptionTSMC's FinFlex standard cells for sub-3 nm nodes provide flexibility and an optimal balance of performance, power, and area. The FinFlex technology offers multiple versions per cell type with varied heights and threshold voltages, allowing cell substitution for placement optimization. This paper introduces the first approach to standard cell legalization for the FinFlex technology, addressing cell substitution, power efficiency, and minimum implant area (MIA) constraints. The proposed algorithm includes three stages: intra-row preprocessing with cell substitution, DAG-based initial legalization with MIA violation prediction, and dynamic programming for inter-row violation removal. Experimental results show superior performance over state-of-the-art techniques.
