Run the Preloaded Diagnostic Tests
Each interface on the S2MB2 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 II Memory Board 2’s Flash memory. If
the S2MB2 does have preloaded diagnostic tests already in Flash, then at power up
the MAX® or MAX II device checks the MPGM value and uses the Flash memory to
configure the Stratix II device with the desired configuration image. This chapter
describes how to set up and perform these preloaded diagnostic tests, including:
User I/O and Nios® Stamp
DDR2 SDRAM dual interface memory module (DIMM)
DDR2 SDRAM devices
QDRII SRAM device(s)
The following sections describe how to perform each test, including the equipment
you need to perform each test, how to set up the board, and the test procedure. Table
2 shows the switch settings you must make to load the designs on power up. If the
Flash is blank or corrupted, there are instructions on how to program the Flash in
“Downloading Factory Image”, Section 3.1.9.
For more details on these designs, refer to Section 3.3, Diagnostic Test Details.
