Research On The Hardware Evolution Method Of Analog Circuits Based On VB Platform

The evolution design of the analog circuits is a branch of hardware evolution, it has importance role to the research of method for hardware evolution, and provides a rationale for realization of hardware evolution. The main body of this paper is analyzing real-time simulation design of analog circuits based on VB platform; it has certain theory and practical value.Firstly the paper has elaborated parameter optimization of analog circuit with VB platform, using VB language with easy to understand and operation to build the service platform of human-machine interaction, and established a basis for following work.Then, the paper proposed a method of evolution design with VB platform for the analog circuit. In the process of evolution design for analog circuit, transferred Hspice for real-time simulation, using the result of simulation to evaluate the fitness, and being the standard of circuit evolution by this achievement, so it can unceasingly evolve the analog circuit, until obtains the most superior individual.The paper take filter's three kind of circuit as examples to verify the method of real-time evolution for analog circuit, proposed the solution for some key questions, given the part programming code and detailed explanation of experiment.
