Task-based multi-process design synthesis with reproducible transforms

Abstract

A task-based multi-process design synthesis methodology is reproducible, and relies on a plurality of child processes to assist a parent process in performing optimizations on an integrated circuit design. Objects from an integrated circuit design are grouped into subsets and assigned to child processes, with each child process performing a transform on each of the objects in the subset assigned to that child process and determining which of the objects in the subset are candidate objects for which performance of the transform has been successful. Each child process also undoes the transform performed for each object such that the same initial state of the integrated circuit design is used to perform each transform. In addition, the parent process tracks the results of performing the transform by each child process, and applies successful transforms in a controlled sequence.
