USB-C Programming Adapter Design

Researching manual options.

Reading docs about How do I mark USB D+ and D- as a controlled impedance pair in Flux? Specifically which inspector properties should be set for the terminals, such as Bus Group, Pair Role, and Controlled Impedance Pair?.

I can’t apply terminal-level controlled-impedance properties directly with my current edit tools.
This is the most relevant entry I found related to the topic:
Defined at terminal level
  • Bus Group: this property defines the different differential pairs. Some interfaces might require many different bus groups (like ethernet), while others only require one (like USB2.0). For example, if a microcontroller contains two USB buses, terminals for one bus should contain “Bus Group” = USB_1 and terminals in the second bus should contain “Bus Group” = USB_ 2
  • Pair Role: defines what type of role the terminal has. For example CLK, D1, D2, D3, D4, TX, TX1, TX2, TX3, RX, RX1, RX2, RX3, etc.
  • Controlled Impedance Pair: this should be a unique name that identifies the pair. This is particularly important for parts that contain more than one bus. For example in a part with two USB buses, you will have two Data 1 pairs. In that case one pair could be named “Data1_Bus1” and the other pair “Data1_Bus2”. You can follow any naming convention you prefer, the only requirement is that each pair has a unique “Controlled Impedance Pair” string.
