altiumschematics
I am drawing a schematic project in PCB Designer and facing the following warnings when I compile the project:
Adding items to hidden net +3.3V
and
Adding items to hidden net Ground
When I double click one of them, For instance (Adding items to gidden net +3.3V), all +3.3V on the schematic sheet are highligheted!
Any idea what does that mean and how to remove the warning!!
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.
Solution found: to see errors in the Compile Errors tab the following steps should be done:
View-->Workspace Panels-->System-->Messages tabCompile Errors tab

Some Altium parts (mostly logic chips) have the supply and ground automatically connected to a supply net (you can spot these parts by their lack of visible power pins), I've never really understood the advantages, try putting a net label or something on a capacitor with the same names as the hidden nets and connect them to your existing power and ground rails as normal. Otherwise those pins might not get connected properly to the rest of the circuit. Altium will still compile with warnings though (one of my boards had several hundred warnings once because the schematic was in mm and the parts were in inches)
