Table 2–15 lists the user-defined DIP switch schematic signal names and their
corresponding Cyclone V GX device pin numbers.
User-Defined LEDs
The development board includes general and HSMC user-defined LEDs. This section
describes all user-defined LEDs. For information on board specific or status LEDs,
refer to
“Status Elements” on page 2–15 .
General LEDs
Board references D4 through D7 are four user-defined LEDs. The status and
debugging signals are driven to the LEDs from the designs loaded into the
Cyclone V GX. Driving a logic 0 on the I/O port turns the LED on while driving a
logic 1 turns the LED off. There are no board-specific functions for these LEDs.
Table 2–16 lists the general LED schematic signal names and their corresponding
Cyclone V GX device pin numbers.
HSMC LEDs
Board references D1 and D2 are LEDs for the HSMC port. There are no board-specific
functions for the HSMC LEDs. The LEDs are labeled TX and RX, and are intended to
display data flow to and from the connected daughtercards. The LEDs are driven by
the Cyclone V GX device.
Table 2–17 lists the HSMC LED schematic signal names and their corresponding
Cyclone V GX device pin numbers.
