Abstract:
A task-based multi-process design synthesis methodology 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 provides result data to the parent process for each candidate object to reduce the overhead of the parent process when performing the transform on the candidate object. The result data, which may include, for example, a set of instructions or hints, may allow a parent process to take advantage of the efforts of the child process in performing the transform.
