Zusammenfassung: | Existing routability-driven placers mostly employ rudimentary and often crude congestion models that fail to account for the complexities in modern designs, e.g., the impact of non-uniform wiring stacks, layer directives, partial and/or complete routing blockages, etc. In addition, they are hampered by congestion metrics that do not accurately score or represent design congestion. This is in large part due to the non-availability of public designs depicting industrial wiring stacks and other complexities affecting design routability.
The aim of the DAC 2012 routability-driven placement contest is to address these issues, by way of the following: (a) release challenging benchmark designs that are derived from modern industrial ASICs, and contain information to perform both placement and routing, (b) present a new congestion metric, as well as an accurate congestion analysis framework to evaluate and compare the routability of various placement algorithms. We hope that a set of challenging benchmarks, along with a standard, publicly available evaluation framework will further advance research in routability-driven placement. |
