I have an issue with altium designer
I am trying to connect a pin from my microcontroller to an external pin for gpio via a bus but I get an error: "duplicate net names wire PA1"
this is what I have:
the microcontroller:
the gpio pins:
How can I solve this issue?
A complete view of the entire schematic:
The best way to do this in Altium is to use Net Ties. These will join two separate nets. See: https://www.smtnet.com/library/files/upload/NetTies-and-How-to-Use-Them.pdf
I will also occasionally use zero-ohm resistors to accomplish the same goal if there is a chance that I may need to break the connection to help troubleshoot an issue.
I ran into the same problem, and I solved it by changing the local net name in the subsheet so that it doesn't match the port name. Below is an example of what I did:

Have you checked the properties of your net labels? If they're supposed to connect to other sheets, you'll need to make sure the net label scope is set to "Global" to make sure all net labels AND all ports with the same name are connected together between sheets. You can change the properties of your net labels by going to Project --> Project Options --> Options tab and change the "Net Identifier Scope" dropdown to "Global". Then click OK.
