Abstract： With the continuous development of semiconductor technology, the scale of chip design is increasing. That makes much more complicated parasitic need to be considered in designs and also makes post-simulation cost much more loading. This article will discuss how to use Cadence's parasitic extraction tool Quantus for post-layout parasitic extraction, and use Quantus' Standalone Reduction(Qreduce) function to simplify the post-imitation netlist to reduce the size of the netlist and increase the speed of simulation. Cadence's Qreduce function is to perform equivalent operations on the RC network through mathematical operations to reduce the number of nodes, thereby reducing the size of the netlist, but at the same time ensuring that the accuracy will not cause a relatively large loss. This article will discuss the degree of post-simulation netlist reduction, the impact of simulation accuracy, simulation speed and memory consumption, and give key comparison indicators.
