The scenario
A USB-C dock design needs a clear switch wiring diagram to route USB2, USB3, SBU, HPD, and CC/PD control signals from the receptacle through a dock switch to downstream hubs and sinks.
What is in this drawing
Read the decisions behind it.
01
Model the PD controller as a separate control block that commands the dock switch.
02
Declare each high-speed and sideband signal (USB2, USB3, SBU, HPD, CC) explicitly for pin-accurate routing.
03
Use generic roles for connector, switch, hubs, and sinks; controller role for PD logic.
Use for hardware documentation, bring-up test plans, or signal integrity reviews of USB-C dock switch wiring.
