The DE2-115 Board has eight 7-segment displays. These displays are arranged into two pairs and a
group of four, behaving the intent of displaying numbers of various sizes. As indicated in the
schematic in
IV E FPGA. Applying a low logic level to a segment will light it up and applying a high logic level
turns it off.
Each segment in a display is identified by an index from 0 to 6, with the positions given in
4-10.
