Abstract： In the process of chip design, static timing analysis is undoubtedly the most important part of the entire design, and it is a priority and problem to be solved in chip design. Nowadays, chip design under nano-scale technology often belongs to multicorner-multimode physical design. The specific combination of process angle and working mode is called scenario. Multi-scenario physical design will bring more stable performance to the chip, but it will also make static timing analysis becomes more complicated. This paper introduces the application of distribute multi-scenario analysis technology in multicorner-multimode physical design. The design practice analysis of the multi-scenario digital chip Cxdp13 based on the Smic 90 nm process shows that under certain hardware conditions, the distribute multi_scenario analysis technology can achieve the purpose of rapid timing sign-off in the physical design of multicorner-multimode.
