Abstract
A system for circuit timing analysis includes a database for holding results of execution of portions of a timing analysis computation. Multiple computation modules are configured for concurrent execution of the portions of a timing analysis computation, for example, a static circuit timing analysis computation. A control subsystem is coupled to the database and to the computation modules, and is configured to receive results of the portions of the computation from the computation modules and to update the database using the received results. Based on the received results, the control module selects further portions of the computations for computation and assign each selected portion to one of the computation modules. The system makes use of parallel processing that is arranged in a way that avoids bottlenecks, such as at least some memory access bottlenecks resulting from data structure locking.
