A Novel Solution for Fast and Efficient Custom Bus Routing with User-defined Reference Wire and Combination of Segmented Bus Option
DescriptionAnalog/Mixed Signal IP/Product have large number of custom bus routings which have been routed manually to meet many requirements (various width/space/layer for matching, IR drop, EM, Noise, etc.). This causes TAT increase continuously by the complexity of advanced node DRC, product size increase, design change, lack of automated solutions. In this paper, we analyzed challenges for custom bus automation and proposed a new custom bus routing solution which enables the fast generation of large number of various bus routings with quality by copying the user defined reference wire information and applying segmented combination of pre-defined bus options. The proposed solution is developed under collaboration of SLSI and Cadence and achieved 63% of TAT reduction at pilot test.
