You can lock the IOmux pads so the pad value is fixed during the resolution process. To lock an IOmux pad:

  1. Select the IOmux you want to modify from the components tree view.

  2. Click the Lock pad check box next to the IOmux pad combo box in the configuration pane to the right. The lock icon changes to red and the IOmux Pad combo box is disabled.

  3. To unlock the pad, click the check box again. The lock icon changes to gray and the IOmux Pad combo box is enabled.

  • The more locked IOmuxes there are, the quicker the resolution process is. However, locking IOmuxes also limits the number of possible solutions to explore for a design.

  • When you lock an IOmux, the resource used by the component is also locked.
