Abstract
A server computer maintains a master database for a PCB design, and a copy of the PCB design is provided to multiple client computers. The server assigns each client a different pair of pins for which a connection must be routed. When a client completes an assigned routing task, it requests that the server update the PCB master design with the route found by the client for its assigned pin pair. After forwarding the request, the client does not update its copy of the PCB design to reflect the found route. Instead, the client returns its copy to the state occupied prior to assignment of the pin pair by the server. Upon receiving notification that the server incorporated the found route, the client updates its copy of the design to include that route.
