4. Run the Preloaded

Diagnostic Tests

Each interface on the Stratix GX development board has an associated

diagnostic test that exercises the interface at the supported I/O rates.

Although the tests are not exhaustive, they help you confirm that each

interface runs according to its intended design. A subset of the diagnostic

tests are loaded into the Stratix GX development board’s configuration

devices, making it easy for you to run any of the tests when you power

up the board. This chapter describes how to set up and perform these

preloaded diagnostic tests, including:

■ User I/O

■ Stratix GX Double Data Rate (DDR) SDRAM Interface

■ Stratix GX HM-Zd SPI-4.2 Loopback

■ Stratix GX HM-Zd XCVR Loopback

■ Stratix GX SFP XCVR Loopback

■ Stratix GX XCVR Eye Diagram

The following sections describe how to perfom each test, including the

equipment you need to perform each test, how to set up the board, and

the test procedure. Table 4–1 shows the switch settings you must make to

load the designs on power up. For more details on these designs, refer to

Chapter 7, Diagnostic Test Details.

User I/O

The user I/O design tests all of the user LEDs, dipswitches, pushbuttons,

and 7-segment displays on the board (the Stratix and Stratix GX devices

each have a set). One pair of pushbuttons controls each device’s user
