Board Trace Model Page (Device and Pin Options Dialog Box)
You open this page by clicking .
Allows you to specify board trace, termination, and capacitive load parameters for each I/O standard. The board trace model parameters specified in this tab are applied to all output or bidirectional pins with the specified I/O standard assigned to them. Board trace model parameters are ignored if applied to anything other than an output or bidirectional pin. You can create board trace model assignments for individual output or bidirectional pins in the Pin Planner.
Note: If Advanced I/O Timing is turned off, Board trace model
parameters are ignored if applied to anything other than an output or bidirectional
pin
in the Capacitive Loading page.
- I/O standard—Allows you to select an I/O standard for which to set or modify the default board trace model.
- Board trace model—Lists the board trace model parameters, with units, and values for the specified I/O standard. You can change the value of each parameter. The board trace model assignments apply to all output and bidirectional pins with the specified I/O standard assigned to them.
