Abstract
A static timing analysis (STA) technique including a main process and a parallel process is described. In the main process, an IC design can be loaded and then linked to a cell library. Timing constraints to be applied to the IC design can be loaded. A timing update for the IC design can be performed. A report based on the timing update can be output. In the parallel process, the interconnect parasitics can be back-annotated onto the IC design. In one embodiment, the interconnect parasitics can be processed and stored on disk. Information on attaching to the stored parasitic data can be generated and provided to the main process during the step of performing the timing update. The parallel process can run concurrently and asynchronously with the main process.
