Understanding Signal Portals
0:24
In Flux, a “Signal Portal” is simply a logical net-tie you place on your schematic to name and carry a signal from one location (or page) to another without drawing wires all the way across. It behaves like a net label on steroids:
- It shows up as a distinct schematic symbol (here, the “Signal Portal” part)
- You give it a name (its net-identifier) and every other portal with that same name will be electrically joined
- Behind the scenes, Flux treats it as the same net—even though you haven’t physically wired a trace between them
- Because it’s purely a connectivity aid, it’s automatically excluded from the PCB and excluded from the BOM
Use portals any time you want to break up long or multi-page nets, or to simplify your drawing by avoiding spaghetti wires.
