Sidewinder: a scalable ILP-based router

Content Provider ACM Digital Library
Author Roy, Jarrod A. Hu, Jin Markov, Igor L.
Abstract We propose Sidewinder, a new global router that combines pattern routing and maze routing in a novel, incremental, ILP formulation. It is the first flat ILP-based approach scalable enough to consider over $10^{4}$ GCells at once. Moreover, it also can be used as a component in previously proposed multi-level and progressive ILP schemes. Sidewinder is particularly good at finding routes with minimal via count, which can improve yield in sub-90nm technologies. Other innovations in our work include an ILP construction based on a dynamically-updated congestion map and the use ofC-shape routes to alleviate local congestion and improve routability. On well-known benchmarks, Sidewinder improves routed wirelength and reduces via count by over 6% compared to ILP-based BoxRouter 1.0 and 35.8% compared to DLM-based FGR 1.0. This easy-to-implement methodology is extensible to detail routing of ASICs as well as FPGAs where it can account for complex design rules and models.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
