Abstract: Processing a circuit design that specifies application logic and debugging logic includes partitioning the circuit design. Each partition includes a part of the application logic and a part of the debugging logic, each partition is specified for implementation on a respective IC die, and the circuit design specifies connections between a part of the application logic in one partition and a part of the debugging logic in another partition. The connections between the part of the application logic in the one partition and the part of the debugging logic in the other partition are changed to connections from the part of the application logic in the one partition to a part of the debugging logic in the one partition. The part of the application logic and the part of the debugging logic of each partition are placed and routed on the respective IC die.

Abstract: The present invention introduces methods of creating floor plans and placements for non Manhattan integrated circuits with existing electronic design automation tools. To create a floor plan, an existing Manhattan based floor planning tool is used. The die size for the floor plan is reduced to take into account the improved wiring density of non Manhattan wiring. A non Manhattan global router is then used on the floor plan to create pin placements. The floor plan may create a floor plan having circuit modules with beveled corners to take advantage of diagonal wiring. To create a placement, an existing Manhattan based placer is first used to create an initial placement. The initial placement is then processed by a non Manhattan aware post processor. The post processor performs local optimizations on the initial placement to improve the placement for a non Manhattan routed integrated circuit.
