Analog IC routing algorithm with Jumper insertion for antenna fixing

As VLSI technology advances to smaller technology nodes, the antenna effect has become a critical issue in the yield and reliability of the VLSI circuit, especially for analog ICs. Jumper insertion is an effective technique to fix the antenna effect. Traditional works on antenna fixing are mainly for digital ICs rather than analog ICs. This paper presents heuristic algorithms for jumper insertion during routing for analog ICs, which handles the expansion limitation of different types of nets, such as general nets and matching nets, and reexamines the matching parameters of matching nets after jumper insertion. The experimental results show the effectiveness of our algorithms.
