PCIe to Nexus adapter

Are there any PCIe to Nexus connector adapters?


For advanced debugging, a Nexus / Aurora high speed debugging interface is needed. For this, some of the SerDes lanes are taken to the dedicated 70-pin connector. This is done in some boards, such as the T2080QDS-PA board.


However, many reference design boards take the corresponding SerDes lanes to a PCIe connector. That is the case for the T2080RDB or the T1040RDB boards.


Looking at the schematics of the T1040RDB PCIe port and at the standard pinout of the Nexus interface, I see that almost all if not all the Nexus signals are available at the PCI-Express connector.


Is there an adapter from the PCIe connector to the 70-pin Nexus / Aurora connector?
