Signal Setup

To configure signal pin assignments using the I/O Wizard Dialog, select the desired pins and click Set as signal pins; this opens the Signal Setup dialog for the selected pins.

Fields in the Signal Setup dialog are editable. You can also select multiple rows and use the Component Setup fields at bottom to make multiple changes to many pins simultaneously.

• The Component field lists components already imported to Designer and represents either an IBIS pin or an IBIS model, depending on the component selected.

• The Model Selector field lists the available models for this component (i.e., the model_sel property of the IBIS component).

• The Pull up to pin field lists non-signal pins (usually Power or Ground) that you wish to connect to the Pull Up pin for the attached buffer. The default is a Power/Ground pin. Alternately, you can choose to select any one-port circuit in the project for the connection.

• The Pull down to pin field follows the same rules as Pull up to pin, with regards to the Pull Down assignment for the attached buffer.

• For I/O Buffers, there is an Enable field that can either be 0V or 1V (depending on how the buffer is configured to operate). The Enable field is only visible for I/O buffers.

• You can also load additional IBIS files by clicking Load models from file to open the Import IBIS File dialog.

Click OK to close the dialog and implement any changes that have been configured.
