【Abstract】 With the background of interactive VLAB design and implementation, the paper solves the problem of routing and connecting each logic cell in drawing logical diagrams interactively. Based on a series of basic principles of routing, a routing algorithm of interactive logic diagrams is presented. It includes three parts: automatic routing, channel expansion and routing improvement. Finally the advantages and shortcomings of this algorithm based on experiments are given.更多还原
