PCI Express Reset Tab

This tab defines the reset signals.

The PCIe PERST_N signal triggers a warm reset. This signal comes from an I/O pad and requires you to instantiate a GPIO and assign it to the resource shown in the Block Editor > Reset tab > PCI Express Reset box. See GPIO Block (PERST_N) for instructions on how to add the required GPIO block.
