Description

technical field [0001] The present disclosure relates to the technical field of integrated circuits, in particular to a calculation method for equivalent resistance of a circuit network between ports, electronic equipment, a server and a storage medium. Background technique [0002] The size of the devices in the circuit and the type of the devices are an important part of the design process that affects the automation of integrated circuits. The current mainstream simulators will optimize the circuit to various degrees. Circuit optimization can reduce the number of components in the circuit on a large scale, thereby reducing the dimension of the equation set and saving the time for solving the equation set. However, while optimizing, the accuracy of the simulation will inevitably be lost, which may lead to the failure of the design. [0003] In the design and development process of electronic equipment, it is usually necessary to analyze the equivalent resistance of the po...
