Well, ocr may fail to route using only two levels of metal layer (this is the default behavior). You should try to increase the number of routing layers with the -l parameter. You can also bound the number of iterations (-i) : the amd2901 core can be routed in less than 15 iterations (depending on the placement and the number of layers). -- | Hugo CLÉMENT <hugo.clement@lip6.fr> | LIP6 / ASIM - Salle 65-66 403 | tél. : 01 44 27 54 15
