Embodiment Construction

[0028] Please refer to figure 1 . figure 1 Shown are the main points (steps) of an embodiment of the method of the present invention. The present invention can synthesize / design / optimize an analog circuit (such as an analog circuit functional block) at the circuit level or system level, and the analog circuit synthesis method of the present invention can include the following points:

[0029] Point S1: Determine the design specification (design spec) and / or design constraint (design constraint) of the analog circuit. In this point, the design specifications / constraints of the analog circuit can be determined according to the user's needs of the analog circuit. For example, in terms of circuit-level design / synthesis, the design specifications of an analog circuit such as an operational amplifier usually include specified gain, slew rate, bandwidth, and so on. Another example: In terms of system-level design / synthesis, the design specifications of analog / hybrid circuits such ...

Abstract

The invention provides a synthetic method for an analog circuit and a related technology. An analog circuit is normally composed of a plurality of circuit units, and the operation and property of each circuit unit is respectively controlled by corresponding parameters. The invention records important design parameters of key circuit units in the circuit units, together with optimization objectives, design specifications and / or design limitations into an optimization plan, and then uses an optimization engine to carry out repeated numerical simulations of electrical layers or system layers of design parameters so as to find out key circuit units and design parameters which conform with the design specifications / the design limitations and approach the optimization objectives, thus automatically and systematically finishing the synthesis / design / optimization of the simulation circuit. The synthetic method and the related technology provided by the invention can respectively synthesize simulation circuits of a same kind with varied specifications under varied technologies, thus giving full play to the advantages of reapplication of synthesized knowledge, reducing the time and cost of simulation circuit design, and improving the productivity of the circuit design.

Description

technical field [0001] The invention relates to an analog circuit synthesis method and technology, in particular to an analog circuit synthesis / design / optimization method and technology in which an optimization plan is used to guide the numerical simulation of an optimization engine. Background technique [0002] Integrated circuits are the most important hardware foundation of the modern information society. As the functions of integrated circuits become increasingly complex and diverse, circuit design becomes more and more difficult. Therefore, the integrated circuit design industry and design tool developers are all committed to research and development of better, more convenient, more systematic, and more automated integrated circuit design methods and technologies. [0003] As known to those of ordinary skill in the art, automated circuit synthesis methods for digital circuits are well developed. The digital circuit designer only needs to describe the input and output...
