Connect net to bus w/ different name

Question

Hi all,

I'm working on my first project on Eagle, and to simplify the scene I decided to use buses. I have 2 buses, names A[0..7] and B[0..7].

On the other side, I have a 40 pins GPIO connector, to connect a raspberry PI zero to the board). I use only the GPIO pins, not the +5V and so on.

To simplify the comprehension of the scheme, I name all connectors I use (26 out of 40) with their respective GPIO ID (GPIO02...GPIO27)

But here comes the problem. If I want to connect some GPIO pins to the buses, this does not work. The nets are names GPIOXX, but the bus want AX or BX.

Is there a way for me to connect those nets to the buses without having this issue ?

I want as much as possible to keep GPIO names on one side and AX / BX names on the other. Also because GPIO pins are not in order, so I don't use them in order on the buses.

Hello,

Unfortunately you can't do what you are trying to do. An entire net can only ever have a single net name and what you are trying to do is name the same net with two different names. Busses are just ways of grouping named nets, not associating different names to the same net. How about you use your AX and BX bus names throughout but then add additional text on the schematic to identify which GPIOXX they are? The down side would be that you would have to really be careful to make sure you kept this up to date if you changed anything at the connector.
