I am working on the pcb board design for E3317-A01 x16 PCIe Tx/Rx swap module.
I am not quite sure the pins for power signals like, VDD_PEXA_12V_RP, VDD_PEXA_3V3_RP, VDD_PEXA_3V3_AUX_RP, as shown below:
Zoomed in version:
Since the board is used to connect two Xavier boards, which means the power signal should come from two Xavier boards. Not sure how to connect these pins.
And for PEX RESET and PEX CLKREQ as shown below, both have a VDD_PEXA_3V3_AUX_EP signal, which I am also not sure where it comes from.
And I also cannot find connection to the signal PEXA_PRSNT_L_RP as shown below:
