The Nuts And Bolts Of Physical Synthesis
SLIP(2007)
摘要
As technology scaling advances to the 45 and 32 nanometer nodes, more devices can fit onto a chip, which implies continued rapid design size growth. Naturally, it becomes increasingly challenging to achieve design closure on these enormous chips with tight performance and power constraints. Physical synthesis has emerged as a critical and powerful component of modem design methodologies to conquer such challenges. Starting from logic-level net list, physical synthesis creates a legally placed design while attempting to satisfy timing, power, and electrical constraints simultaneously. This paper briefly outlines the core components of physical synthesis timing closure and discusses some recent techniques that improve the solution quality and throughput of the physical synthesis process.
