Optimized routing strategy for multiple synchronous bus groups

摘要: A bus routing strategy for a printed circuit board is disclosed. The ensures that traces coupled to plurality of synchronous devices are not routed through the center region each package, trace in approximately same length, minimizes length over which “neckdown” occurs, and without making sharp turns. By using this strategy, propagation time differences within group minimized. Also, regions under package available vias connected bypass capacitors.
