Abstract:
Partitioning of a design allows static timing analysis (STA), signal integrity, and noise analysis to be performed in parallel on multiple, less demanding, and more available hardware resources. Therefore, runtime and throughput of the analysis can be significantly shortened. Notably, the partitioning can include redundancy. That is, partitions are allowed to share objects in order to preserve the timing path completeness and design structural integrity. Due to this redundancy, these partitions can account for many constraints specifically imposed by STA and ensure minimal inter-partition data dependency during the analysis. Once these partitions are populated, analysis can be performed on those partitions in parallel to generate the same timing results as if the design had been analyzed flat as a single unit. Therefore, the performance of the analysis can be optimized without compromising the accuracy and quality of results.
