Abstract

A method for optimizing that equivalent output of post-simulation circuit comprises the follow steps: 1) discriminating the output information required by circuit simulation and filter the equivalentoutput information; 2) storing the RC matrix before optimization in advance; 3) optimize that circuit and storing the optimize node information; 4) updating the RC matrix before optimization and solving to obtain the corresponding output information of the optimized node; 5) outputting the equivalent output information of the node. The method of the equivalent output after optimization of the post-simulation circuit of the invention ensures the integrity of the output according to the equivalence of the post-simulation circuit and realizes user-friendliness.

Description

technical field [0001] The invention relates to the field of integrated circuit automation product design, in particular to a method for equivalence of outputs after circuit optimization in integrated circuit design. Background technique [0002] The scale of equations in electronic circuits is an important factor restricting the performance of integrated circuit automation products. At present, most of the products on the market will optimize the circuit in advance to reduce the circuit scale, thereby reducing the complexity of the equation system calculation. However, most circuit optimizations are restricted by various factors, including the influence of circuit output information, which will reduce the efficiency of our circuit optimization. With the continuous progress of the technology to the nanometer level, the scale of the circuit is also expanding rapidly, and the scale of the problem to be solved is also increasing rapidly. It affects the design scale and design...
