Problems solved by technology

These methods of describing analog circuits can only simplify multi-terminal devices to two-terminal devices when realizing the connection problem of multi-terminal devices (such as transistors), making it difficult to design complex circuit structures to meet the high performance requirements of users for circuits.

Abstract

The invention discloses an analogue circuit data array describe method, belonging to the analogue circuit automatic design technique. (1), concluding and attaining 16 sub-circuits, and using topological character data array, topological structure data array and topological port data array to independently describe the element property, topological connecting relationship and the port property of each sub-circuit; (2), when describing analogue circuit, referencing said 16 sub-circuits to divide the elements into several circuit modules; (3), when the invention is used in amplify circuit topological automatic design, referencing the sub-circuit port property described by the topological port data array and the sub-circuit element character described by the topological character data array, via editing the topological structure data array, realizing the automatic generation of amplify circuit topology. The invention can describe most analogue circuits with wider application.

Description

technical field [0001] The invention relates to the technical field of analog circuit design automation, and provides an analog circuit data array description method. Background technique [0002] The analog circuit design cycle is long and requires designers to have sufficient basic circuit knowledge and rich analog circuit design experience, which has become an obstacle to the development of analog circuit design. One of the ways to solve these obstacles is to realize the automatic synthesis of analog circuits. Another problem that follows is how to describe the analog circuit in the automatic synthesis of the analog circuit. [0003] In the existing automatic circuit synthesis algorithm, when the genetic algorithm is used for the automatic synthesis design of the analog circuit, a linear sequence is used to describe the analog circuit; Connections describe analog circuits. These methods for describing analog circuits can only simplify multi-terminal devices to two-term...
