Multiple drivers
▲ warningWhat it checks
More than one output terminal driving the same net.
Why it matters
Two push-pull outputs on one wire fight: whichever loses sources current into the other, both heat, and the level is whatever the strongest driver says. Legitimate exceptions exist — open-drain buses and diode-OR'd supplies are designed for exactly this.
How to fix it
If it's a real conflict, gate one driver or mux them. If it's open-drain or diode-OR'd by design, acknowledge the finding with a note — that keeps the checker honest without nagging you.
When it's intended
I²C, alert lines, and diode-OR'd power are the textbook intended cases — mark them intended once and the note travels with the design. In the editor, mark any error or warning intended with a note — it mutes the finding without hiding it, and the note stays with the design.
