We propose a method for VLSI interconnect global routing that can optimize routing congestion, delay and number of bends, which are often competing objectives. Routing flexibilities under timing constraints are obtained and exploited to reduce congestion subject to timing constraints. The wire routes are...
We address the problem of incorporating RC delay constraints into global routing. In contrast to the usual global routing approach that focuses on minimizing net length while obeying constraints given by other tools such as layer assignments, our method natively works on the timing graph and consider...
The timing-driven global routing problem is formulated as a multiterminal, multicommodity network flow problem with integer flows under additional timing constraints. Two novel performance-driven Steiner tree algorithms are proposed to generate the initial global routing trees. A critical-path-based ...
objectives during global routing include minimizing total wirelength, mitigating routing congestion, or meeting routing resource constraints. If timing critical paths are known, they can also be put in the design objectives during global routing, along with other metrics such as manufacturability and ...
The coupling effects have brought new challenges to routing algorithms on both delay estimation and optimization. In this paper, we propose a timing-driven global routing algorithm with consideration of coupling effects. The two-phase algorithm based on timing-relax method includes a heuristic Steiner...
