188.8.131.52. Modifying the Board Trace Model
To modify the board trace model, click View > Board Trace Model in the Pin Planner.
You can modify any of the board trace model parameters within a graphical representation of the board trace model.
The Board Trace Model window displays the routing and components for positive and negative signals in a differential signal pair. Only modify the positive signal of the pair, as the setting automatically applies to the negative signal. Use standard unit prefixes such as p, n, and k to represent pico, nano, and kilo, respectively. Use the short or open value to designate a short or open circuit for a parallel component.
