altiumerrorschematics
I'm having a hard time with this problem and cannot figure out how to deal with it. As shown in the figure below, ADC[0..2] is going out from A2 and A3 and in to A1:
In details:
All three pins are inputs in A1, this connection seems to be logical, but Altium didn't like it!!
So the question is: How can I get multiple output sheet entries without Errors ?
Can you post your sub-sheets?
From looking at what you have posted, I think you may have a typo in the entry: RB[0..7]. You typically get the red line below the entry when it is not correctly tied to a port on the child-sheet.
Right-click on the sheet symbol, and select "Sheet Symbol Actions" -> "Synchronize Sheet Entries and Ports"
Anyways,
I created a simple, minimal test schematic to do what you are doing:
Top Sheet:
Sheet 1:
Sheet 2:
Project Hierarchy:
And it properly connected the nets across the different schematics:
For what it's worth, I am fairly sure you have to both name the buses with net-labels on each child-sheet, and name the ports.
Also, the bus name and wire names have to have the same prefix:
For example, a set of wires HERP0 HERP1 HERP2 HERP3 HERP4 has to be in a bus named HERP[0..4]. It may also have to be zero-indexed (i.e. start at 0, rather then 1), but I'm not totally positive on that.
Also, I do indeed get the "Net NetName has multiple names" warning, but it's just that, a warning. You can turn the warning off, or just ignore it. I tend to leave it on, and before I have a board produces, go through all the warnings and make sure that I intend for whatever they refer to to be that way.
Figured out a workaroud: Made the sheet containing the channel sheets the top sheet by adding sheet symbols for the two other subsystems in the design.

For now you have two buses with same name, that is how Altium sees it, and it makes sense. ADC[0..2] on both sheets. You can not make Output for bus containing 3 signals, from two different sheets. Your A2 sheet contains only one signal and A3 two signals, so solution is to make Bus entries at top level and connect those signals with outputs from sheets A2 and A3. You can name your signals as ADC 0, ADC 1, ADC 2. ADC 0 is output from A2 and is connected to the bus over bus entry, same is with ADC 1 and ADC 2. And input to A1 can be same as it is now.
