Abstract

The invention provides a circuit simulation method and device, a storage medium and electronic equipment. The method comprises the steps: obtaining an initial value of a model parameter of a target circuit and a target value of a circuit parameter; setting a first model parameter value and a second model parameter value according to the initial value of the model parameter, the first model parameter value being larger than the initial value, and the second model parameter value being smaller than the initial value; performing simulation according to the initial value, the first model parametervalue and the second model parameter value to obtain a corresponding initial circuit parameter value, a first circuit parameter value and a second circuit parameter value; determining a value interval where a target model parameter value corresponding to the target circuit parameter value is located according to the initial circuit parameter value, the first circuit parameter value and the secondcircuit parameter value; and performing simulation for multiple times in the value interval to obtain the target model parameter value. The efficiency can be improved, and the operand can be reduced.

Description

technical field [0001] The present application relates to the technical field of integrated circuit simulation, in particular to a circuit simulation method, device, storage medium and electronic equipment. Background technique [0002] At present, in order to make the performance of the manufactured chips meet the preset product requirements, local adjustments to the process are generally adopted. At present, a SPICE (Simulation program with integrated circuit emphasis) integrated circuit simulation program is usually used for circuit simulation, so as to adjust electrical parameters of certain devices. Among them, since the process characteristics can be characterized by the electrical parameters of the device. Therefore, by changing the process parameters of specific electronic components in the SPICE model, the performance of functional devices can be changed, the changes in circuit simulation performance parameters can be observed, and the optimized device parameters a...
