Abstract

The invention discloses an automatic design method and device for analog circuit based on a tree structure, equipment and a medium. The automatic design method of the analog circuit based on the tree structure comprises the following steps: setting the maximum height and growth direction of the tree structure; randomly calling nodes from the function node library as father nodes; randomly calling nodes as child nodes from the function node library and the port node library according to the growth direction; if the child nodes are terminal nodes, generating a tree structure; checking the tree structure, and if the tree structure meets a preset condition, obtaining a circuit topology and device parameters conforming to a circuit rule; evolving the circuit topology and the device parameters to generate an analog circuit. According to the invention, the tree structure of the designed analog circuit is more reasonable.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automatic circuit design, and in particular, to a method, device, device and medium for automatic design of analog circuits based on a tree structure. Background technique [0002] Automated circuit design has attracted increasing attention, and analog circuit design automation is particularly challenging due to the complex topology and parameter selection involved. There are many methods for studying the automation of analog circuit design, including methods based on domain knowledge, evolutionary algorithms, and simulated annealing. The method based on domain knowledge has a high demand for circuit knowledge for designers. The method of simulated annealing and evolutionary algorithm have been widely used in automatic circuit design because of their characteristics of not relying on domain knowledge. Genetic programming is a type of evolutionary algorithm. As a global optimization ...
