Abstract
Embodiments of the present invention provide a PIPE5 to PIPE4 converter to provide compatibility between a PIPE5 controller and a PIPE4 test device. The converter includes a first interface coupled to the PIPE5 controller including MAC registers through a message bus interface, a second interface coupled to the PIPE4 device through a PCIe link and PHY registers. When a first message bus interface signal is received from the PIPE5 controller, the first interface finds a target PHY register based on the first message bus interface signal, and the second interface generates a first link interface signal associated with the target PHY register and outputs the first link interface signal to the PIPE4 device.
