PCI Express RP Outbound Tab

In the RP Outbound tab you configure the root port. If you have not yet configured anything, this tab only shows the Root Port Outbound Settings button. Click it to open the Root Port Outbound Settings dialog box where you create and configure regions. After you have configured one or more regions, the RP Outbound tab shows a summary of the region settings.

You can enter cofigurations for up to 32 regions in the Root Port Outbound Settings dialog box. Click the Verify button to perform a design check. If the software finds any configuration errors, it highlights them in the Console. Refer to Design Check: PCI Express Messages for a description of the error messages. When you finish configuration, the software saves it into the specified .json file in your project directory.
