Dear grouting (global routing) contest participants, I just released two sample (but much more serious) benchmarks at the global routing contest website: http://www.sigda.org/ispd2007/rcontest/adaptec1.capo70.rin.gz http://www.sigda.org/ispd2007/rcontest/adaptec1.capo70.2d.rin.gz http://www.sigda.org/ispd2007/rcontest/adaptec3.dragon70.rin.gz http://www.sigda.org/ispd2007/rcontest/adaptec3.dragon70.2d.rin.gz You'll find two versions per benchmark, 3D version and 2D version. Virtually they represent the same problem instances, but 3D version uses 6 metal layers while 2D version uses only 2 metal layers with higher capacity. I'd like to ask you to try these benchmarks and if you find any problem, let me know as soon as possible. Since the real contest starts next week (please see the tentative schedule below), it's important for you to let me know within a week. Please note that each pin's location is represented with real x/y coordinates, NOT tile indices. This was intentional for the potential detailed routing contest in the future. However, we realized that this causes confusion and there exist differences between our output format and BoxRouter format. Please follow our output format. Then, what if two pins fall into the same tile? In this case you don't have to global route these two pins. Also, I'm going to only check whether your end point of global path (real x/y coordinates) is in the same tile with your pin (x,y) tile. I.e., I'm NOT going to directly check the equality of pin (x,y) and global_route_endpoint (x,y). In other words, the evaluation will be tile-to-tile checking, not pin-to-pin checking. Also, these benchmarks include some extremely high fanout nets. If the degree of nets (# of pins) is over 1000, you don't have to route those nets. Those nets can be included in your solution file anyway, but those net solutions will be ignored during evaluation. Hope this clarify the issue. The schedule: 02/12: two sample benchmarks are released 02/18: sample benchmark solutions and binary due 02/19: real global routing contest starts with 8 benchmarks. Also, evaluation script will be released too. 03/09: contest solutions and binary due If you have any question, please let me know. Regards, Gi-Joon --
