Abstract:
A flexible and extensible automated design partitioning mechanism that facilitates simulation sessions employing two or more simulators is provided. A simulation backplane includes partitioning logic that identifies the design blocks of an overall design pertaining to each of a plurality of simulators. Once the partitions have been identified, nets that cross simulator boundaries (e. g. , mixed nets) are determined and inter-simulator connectivity information is generated for the simulators. According to one aspect of the present invention, the partitioning logic is able to accomodate arbitrary (e. g. , instance-based) partitioning. A design source expressed in a design representation upon which a first simulator may operate is received. Design blocks to be partitioned to each of a plurality of solvers are identified based upon one or more partitioning directives and the design source. A first instance of a cell is assigned to a first solver and a second instance of the cell is assigned to a second solver.
