尝试画个层次原理图,很简单,就几个电阻一连,可以画完了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)
Block Pin名DD[1..4],bus 名 DD[1..4],net alias,DD1,DD2,DD3,DD4.
为啥报错呢?
如果把根图中总线上的net alias拿掉,倒是不报错,改警告了:
WARNING [DRC0030] Bus width is not matching with the port Width block1,DD[1..4]: SCHEMATIC1, top (2.45, 2.30)
