A wire and a bus can be connected by the following methods:

  • using s bus entry item and net aliases for specifying the signal travelling onto the bus.
  • If you begin or end a wire segment on a segment of a bus, Capture adds a junction (if they T-intersect), and they will be connected.
  • If you begin or end a bus segment on a segment of a wire, Capture adds a junction (if they T-intersect), and they will be connected.

 Wires and buses, along with other parts and symbols in the project that are logically connected via net names, form a net. When you place a wire, it is assigned a system-generated netname, which you can replace with an alias or a different netname.

 

Once a bus acquires a valid name or alias, that name or alias defines the signals carried by the bus and connects those signals to the corresponding nets. For example, the alias A[0:3] defines a four-signal bus and connects the four signals it carries with nets A0, A1, A2, and A3.

 

When you connect a wire to a pin, Capture provides visual confirmation of the connection by removing the unconnected pin box on the pin. If two continuous wires cross at 90°, they are not electrically connected unless you create a junction by clicking the left mouse button as you draw a wire across an existing wire.

 

You can determine whether wires or buses that cross each other are connected by the presence or absence of a junction. Unless a junction is present, wires or buses that cross each other are not connected. If you drag a net up to another net so that they touch, Capture adds a junction where the nets meet and the two nets are connected.
