Figure 2-2: Complete Gen1 ×8 Endpoint (DUT) Connected to Example Design (APPS)
The example design includes the following components:
• DUT—This is Gen1 ×8 Endpoint. For your own design, you can select the data rate, number of lanes,
and either Endpoint or Root Port mode.
• APPS—This Root Port BFM configures the DUT and drives read and write TLPs to test DUT
functionality. An Endpoint BFM is available if your PCI Express design implements a Root Port.
• Transceiver Reconfiguration Controller—The Transceiver Reconfiguration Controller dynamically
reconfigures analog settings to improve signal quality. For Gen1 and Gen2 data rates, the Transceiver
Reconfiguration Controller must perform offset cancellation and PLL calibration. For the Gen3 data
rate, the pcie_reconfig_driver_0 performs AEQ through the Transceiver Reconfiguration Controller.
