摘要：A method and system to improve the performance of an integrated circuit (IC)
chip by removing timing violations detected by performing a statistical timing analysis,given distributions of process and environmental sources of variation. The distributionsare quantized using a minimum distortion criterion into discrete values. For each timingnode of the IC circuit, a discrete minimum and maximum operation is performed on thetiming parameters using a subset of combinations of the discrete values. The results ofthe discrete minimum and maximum operation are then de-quantized and propagated toa subsequent timing node and edge thereof. The process continues until one or moreprimary inputs and outputs of the IC chip are reached. The design of the IC chip ismodified by removing all the timing violations identified.
