vertical constraints graph (VCG)垂直约束图 A directed graph associated with the channel routing in LSI layout. The node of the graph represents a net in channel routing. If there is a directed edge from the node i to j, that means the net corresponding to the node i must be placed a bove the net j corresponding to the node j according to the design rule in LSI layout. 一个与大规模集成电路布图中通道布线有关的有向图。图上的节点对应通道布线中的一个线 网。如果从节点i到节点j有一个有向边,则表示与节点i对应的线网根据设计规则必须布在 与j对应的线网之上。 |
