CASE ANALYSIS
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.
Key decisions
- Model the PD controller as a separate control block that commands the dock switch.
- Declare each high-speed and sideband signal (USB2, USB3, SBU, HPD, CC) explicitly for pin-accurate routing.
- Use generic roles for connector, switch, hubs, and sinks; controller role for PD logic.
When to reuse this
Use for hardware documentation, bring-up test plans, or signal integrity reviews of USB-C dock switch wiring.
