Abstract

A hybrid hierarchical timing closure methodology has been developed to combine strength of the subchip based hierarchical timing closure method and flat design based logic-physical combined optimization method for a 1.5 million gate, high performance and ultra-low power DSP which has been used in a number of wireless applications. The principle and the implementation details of the methodology are provided.
