Method Detail

abutRouteBotTop

public static void abutRouteBotTop(NodeInst bot,
                                   NodeInst top,
                                   double distFromBoundary,
                                   java.util.List<ArcProto> layers)

Connect ports on the top edge of bot that line up exactly with corresponding ports on the bottom edge of top. Only connect those ports that attach to metals in layers. layers must be sorted from lowest to highest

abutRouteLeftRight

public static void abutRouteLeftRight(NodeInst left,
                                      NodeInst right,
                                      double distFromBoundary,
                                      java.util.List<ArcProto> layers)

Connect ports on the right edge of left that line up exactly with corresponding ports on the left edge of right. Only connect those ports that attach to metals in layers. layers must be sorted from lowest to highest
