Hello, i am a student studying allegro pcb designer. I have trouble in routing a bus. I think all of channels in a "bus" must have same( or very similar) characteristics so that they must be routed in a same topology (very close paths). I just realized the way how to make a bus and add channels in the bus. However, i can't route them together simultaneously. I want to know the exact meaning of "bus" and how to route a bus simultaneously. Thank you for reading a long boring question, and i am waiting for a valuable answer.
