Abstract

The authors describe novel techniques for simultaneous device placement and detailed routing of analog cells. Both nets and devices are treated as placeable, malleable objects in a common simulated-annealing framework. A detailed routing abstraction called a k-bend net limits the complexity of each net's topology, and allows simple incremental net reshaping during annealing. Analog layouts in which the critical interacting nets are simultaneously embedded during device placement prove to be superior, in terms of performance-limiting crosstalk violations, to sequentially placed and routed layouts.
