Group buses can be used to bundle together related signals even when they have different names. Here is the description from the documentation:Ī group bus is a collection of one or more signals and/or vector buses. The upcoming KiCAD 6 release has a new “group bus” that should do what you want. Unfortunately, the current release only handles “vector buses”, which are the style that you described. Otherwise, you need to use a double of more than a dozen labels to connect, which adds a lot of extra work when drawing and checking. Therefore, if a “bus” type of wiring harness can be added, the Ethernet and MCU sub-pictures only need a pair of “harness” labels to connect, for example, the wiring harness named “ethernet_bus” (similar to the bus). In fact, I always I have to zoom in many times to see if each connection point is correct. What’s even more unfortunate is that on 4K resolution monitors, because of the lack of “magnetic attraction” function, when there are a lot of connections on the schematic, it is difficult to check whether the connection being operated is really correct. ![]() Only a lot of wires can be used to indicate the connection, which makes the connection relationship on the schematic display very messy. In KiCAD, the current bus type uses the same prefix plus a changing number to name each signal line, for example, address lines A0, A1, A2… However, the name of the control bus signal of the Ethernet is not expressed in this way, so it cannot be expressed in the naming form of the standard bus.
