本文介绍了一种基于优化的、层次式的D/A转换器自动综合方法.该方法根据总体性能要求首先确定对各单元电路的性能要求,再由这些性能要求驱动相应的单元电路综合模块进行单元电路的综合,最后采用一个自下而上的过程验证所产生的D/A转换器的性能.在两个综合层次上,利用多维下降单纯形优化算法来进行优化求解 This paper presents an optimized and hierarchical D / A converter automatic synthesis method, which firstly determines the performance requirements of each unit circuit according to the overall performance requirements, and then drives the corresponding unit circuit synthesis module Unit circuit synthesis, and finally use a bottom-up process to verify the resulting D / A converter performance.On the two levels, the use of multi-dimensional descent simplex optimization algorithm to optimize the solution
