Method for predicting circuit performance by using machine learning

Abstract

The invention combines an integrated circuit, a complex network theory and machine learning, and provides a method for predicting circuit performance by using machine learning. The method includes the steps of generating a data set, obtaining an optimized machine learning model and predicting the circuit performance by using the machine learning model. The data set generation part comprises the following steps: firstly, performing layout and wiring on an initial circuit by utilizing an EDA tool to obtain circuit performance and a wiring layout after wiring, then performing complex network modeling on the wiring layout, and finally extracting corresponding complex network characteristic parameters through a complex network analysis tool. The step of obtaining the optimized machine learning model comprises the steps of dividing a data set into a training set and a test set, training the machine learning model by using the training set, evaluating the obtained machine learning model by using the test set, and carrying out model optimization. The step of predicting the circuit performance by using the machine learning model comprises the steps of extracting complex network characteristic parameters of a to-be-tested circuit, inputting the complex network characteristic parameters into the optimized machine learning model, and predicting the circuit performance.
