General Purpose LEDs
(see Appendix A, Figure 27, D14-D21)
LEDs are provided along the back panel edge of the PCB. These LEDs are connected to general-purpose FPGA
I/Os. The LEDs are illuminated by the associated FPGA outputs being driven to a valid LOW level. The use of these
LEDs is defined for PCI Express applications to observe the status of the PCI Express link during operation. The
LEDs must be included in the FPGA design. These status LEDs are available in both x1 or x4 configurations. The
back panel marking reflects PCI Express specific status.
