Abstract: Techniques for circuit concurrent gate sizing and repeater insertion considering the issue of size conflicts are described herein. Certain of these techniques can be directed to coupled gates within levels of a levelized circuit falling within a coupling window defined by a minimum slack gate and adjacent gates coupled to the minimum slack gate with an adjacency parameter less than a predefined adjacency limit.

Abstract: A system and method for topology construction for long and complex fan-out networks such as encountered in microprocessors include a modified Steiner tree algorithm with concurrent buffering to reduce post-buffer power/delay cost for a spanning tree. The system and method may prune Hanan points prior to calling a buffering tool to insert buffers and insert non-Hanan branching points. Embodiments may also include dividing a device into a plurality of super unit blocks, performing routing within each of the plurality of super units using a single crossing Steiner tree algorithm to determine a corresponding port, and aligning corresponding ports of each super unit to provide routing between the plurality of super units.

Abstract: An improved, systematic approach is provided for automatically determining which cells in a circuit should be replaced to satisfy timing adjustment requirements (TAR's), and automatically replacing the cells with replacement cells to meet the TAR's. With the improved approach, there is a high likelihood that an optimal replacement scheme will be found which requires the fewest number of cells to be replaced while still satisfying all of the TAR's.
