Development Board Components

LED Pin List

Table 2–12 lists the FPGA pins assigned to the LEDs.

Seven-Segment Displays

The development board provides four adjacent 7-segment displays,

HEX0–HEX3, (Figure 2–16) for reporting numerical values from the

FPGA. Each segment connects to an FPGA general-purpose I/O pin. A

LOW logic level applied at the pin lights up the segment; a HIGH logic

level turns the segment off.
