Table 2–28 lists the HSMC user-defined LED schematic signal names and their

corresponding Stratix IV E FPGA pin numbers.

Table 2–29 lists the HSMC user-defined LED component reference and the

manufacturing information.

Seven-Segment LED Display

The development board includes one quad digit seven-segment LED display. The

display is controlled by the Stratix IV E FPGA device. Each segment of the display can

be illuminated by driving a logic 0 to the connected device's I/O pin.

Table 2–30 summarizes the display segments and pin assignments for the

seven-segment LED display.
