Abstract

A novel substrate coupling simulation tool named SubCALM is presented. It is well suited to floorplanning of large mixed-signal designs since it exploits the boundary element method and contains a Poisson solver based on a hierarchical O(n) conjugate gradient algorithm. Sophisticated preconditioners are applied, which further increase the computation speed by a factor of about 10. The approach is verified by experimental results in a 0.25 μm BiCMOS technology.
