Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to an abnormality detection method and device for a circuit simulation model. Background technique [0002] With the development of integrated circuits and the expansion of the scale of electronic circuits, the requirements for simulation speed and simulation accuracy of circuit simulation software are getting higher and higher in the prior art. Circuit simulation is mainly used for simulating the circuit structure. By constructing the circuit component model, the mathematical model that can correctly reflect the physical and electrical characteristics of the physical device is used to replace the specific physical device, and the physical problem is transformed into a mathematical problem to establish the circuit. The relevant models and equations are analyzed and calculated by computer, and the solutions of the equations are obtained to simulate the circuit characteris...
