尝试画个层次原理图,很简单,就几个电阻一连,可是画完了DRC的时候总是报错:
Checking Misleading Tap connection
ERROR [DRC0039] Tap may not be connected with the bus Check Entire net. DD1: SCHEMATIC1, top (3.55, 2.30)
ERROR [DRC0039] Tap may not be connected with the bus Check Entire net. DD2: SCHEMATIC1, top (3.55, 2.30)
ERROR [DRC0039] Tap may not be connected with the bus Check Entire net. DD3: SCHEMATIC1, top (3.55, 2.30)
ERROR [DRC0039] Tap may not be connected with the bus Check Entire net. DD4: SCHEMATIC1, top (3.55, 2.30)
hierarchical pin name D[1..4],
bus name DD[1..4],
net alias 分别为DD1,DD2,DD3,DD4。
问题出在哪呢?如果把根图上的bus name 去掉,就又报警了,
