User-Defined LEDs
The FPGA board consists of 10 user-controllable LEDs to allow status and debugging signals to be
driven to the LEDs from the designs loaded into the Stratix V GX device. Each LED is driven
directly by the Stratix V GX FPGA. The LED is turned on or off when the associated pins are
driven to a low or high logic level, respectively. A list of the pin names on the FPGA that are
connected to the LEDs is given in

7-Segment Displays
The FPGA board has two 7-segment displays. As indicated in the schematic in
the
seven segments are connected to pins of the Stratix V GX FPGA. Applying a low or high logic level
to a segment will turn it on or turn it off, respectively.
Each segment in a display is identified by an index listed from 0 to 6 with the positions given in
. In addition, the decimal point is identified as DP.
shows the mapping of the
FPGA pin assignments to the 7-segment displays.
