Abstract :
The hierarchical substrate coupling simulation tool Sub-CALM offers the opportunity to estimate substrate coupling on floorplan level. A novel approach for modeling well and SOI structures in a boundary element description is introduced. Several acceleration techniques like precalculated macromodels and sophisticated preconditioning algorithms are presented which are applied to an O(n)-conjugate-gradient Poisson solver in order to be able to process large full-chip layouts during floorplanning.
