User Guide
User LEDs
The User LEDs control displays the current state of the user LEDs. To toggle the board
LEDs, click the 0 to 7 buttons to toggle red or green LEDs, the All button, and the
graphical representation of the LEDs.
Push Button Switches
The read-only Push button switches (S8-S10) control displays the current state of the
board user push buttons. Press a push button on the board to see the graphical display
change accordingly.
The FMC/C2C Tab
The FMC/C2C tab allows you to perform loopback tests on the FMC XCVR and FMC
parallel ports, Chip-to-Chip (C2C) XCVR, C2C LVDS, and C2C single-ended
loopback. FPGA 1 is configured with a design for FMC testing and C2C testing.
FPGA2 is configured with a design for C2C testing.
1
Altera recommends loading the C2C loopback design without Nios configured to
FPGA2. Configuring the FPGAs through the BTS GUI handles this by default.
