Description

technical field [0001] The invention relates to the field of integrated circuit design automation, in particular to a circuit optimization method and device for analog circuit transplantation. Background technique [0002] The high degree of automation of digital integrated circuit design makes the design cycle of digital integrated circuit greatly shortened. In contrast, the highly manual design of analog integrated circuits makes the design cycle of analog integrated circuits generally two or three times that of digital integrated circuits. Therefore, the design cycle of mixed-signal integrated circuits is subject to the design cycle of analog integrated circuits. If the automation of analog integrated circuit design is improved, the design cycle of analog integrated circuits can be shortened, and the design cycle of mixed-signal integrated circuits can be significantly shortened, its design cost can be reduced, and product competitiveness can be improved.
