Latest Patents
Ling-Hui Hao holds a patent titled "Automatic DCS routing for multilayer packages to minimize coupled noise." This patent describes a routing method for differential current switch (DCS) pairs that optimizes the routing process to enhance performance. The method involves initially shortening the min/max length window for a first routed rail, thereby increasing the likelihood that the length of the second rail will fall within the specified window. The routing domain for the first rail is then modified to direct the first pin exit toward the second pin of the differential current switch pair. A suitable algorithm, such as a prior art mazerouter algorithm, is employed to route the first rail along a path restricted to the routing domain. The program ensures that a proposed via connection is accepted only if there is an available adjacent via for routing the second rail. If no such via is available, the proposed route for the first rail is rejected. This innovative approach significantly improves the efficiency and reliability of multilayer package designs.
