Proceedings ArticleDOI
Quantifying academic placer performance on custom designs
TL;DR: This work presents two custom constructed datapath designs that perform common logic functions with hand-designed layouts for each and experiments show that all academic placers have wirelengths significantly greater then the manual solution.
Journal ArticleDOI
Obstacle-Avoiding and Slew-Constrained Clock Tree Synthesis With Efficient Buffer Insertion
TL;DR: A novel obstacle-avoiding CTS approach with slew constraints satisfied and signal polarity corrected is presented, which effectively overcomes the negative influence on skew brought by the obstacles.
Proceedings ArticleDOI
Wire synthesizable global routing for timing closure
Michael D. Moffitt,Cliff Sze +1 more
TL;DR: A method of progressive projection to account for wire tags and layer directives, in which classes of nets are successively applied and locked while performing partial aggregation, effectively models the resource contention of layer constraints by faithfully accumulating capacity of bounded layer ranges.
Proceedings ArticleDOI
CATALYST: planning layer directives for effective design closure
TL;DR: This work proposes a new algorithm, CATALYST, to perform congestion- and timing-aware layer directive assignment and balances routing resources among metal stacks so that designs benefit from the availability of thick metal layers by achieving improved timing and buffer usage reduction while maintaining routability.
Journal ArticleDOI

TL;DR: The most critical methodology innovations specific to POWER7 design are described, which were in modularity, timing closure, and design efficiency.
