The QDMA supports the PIPE mode simulation where the PIPE interface of the core is connected to the PIPE interface of the link partner. This mode increases the simulation speed.
Use the Enable PIPE Simulation option on the Basic tab of the Customize IP dialog box to enable PIPE mode simulation in the current Vivado® Design Suite solution example design, in either Endpoint mode or Root Port mode. The External PIPE Interface signals are generated at the core boundary for access to the external device. Enabling this feature also provides the necessary hooks to use third-party PCI Express® VIPs/BFMs instead of the Root Port model provided with the example design.
