The DDR2 SDRAM DIMM test uses a hardware state machine included in the DDR2
MegaCore® function, and a DDR2 SDRAM DIMM to test the DDR2 SDRAM interface.
The example driver is a self-test module that issues read and write commands to the
controller, and checks the read data to produce the pass/fail and test complete signals.
The example driver generates a pseudo-random binary sequence (PRBS) that is written to
the DDR2 SDRAM DIMM, then read back and compared with the transmitted data. The
test reads and writes across the entire address range of the DDR2 SDRAM DIMM. The
board has been tested with the following DDR2 module, and is expected to be compatible
with other industry standard DDR2 modules:
• Micron Technology MT9HTF3272AG-53E
Refer to the DDR2 & DDR2 SDRAM Controller Compiler User Guide for information
regarding the example driver and the DDR2 SDRAM MegaCore function.

DDR2 SDRAM Devices Test
This section describes the DDR2 SDRAM Devices test. Refer to “DDR2 SDRAM
Devices” in section 3.1.7 for information on how to perform the test. The DDR2 SDRAM
test uses the Altera® DDR2 SDRAM MegaCore® function, the example driver provided
with the MegaCore function, and some logic to indicate the status of the test. This test
reads and writes pseudo-random binary sequence (PRBS) data to and from the DDR2
SDRAM. The MegaCore function also includes a testbench, and simulation instructions.
The DDR2 SDRAM test uses a hardware state machine included in the DDR2
MegaCore® function, and four DDR2 SDRAM devices to test the DDR2 SDRAM
interface.
The example driver is a self-test module that issues read and write commands to the
controller, and checks the read data to produce the pass/fail and test complete signals.
The example driver generates a pseudo-random binary sequence (PRBS) that is written to
the DDR2 SDRAM devices, then read back and compared with the transmitted data. The
test reads and writes across the entire address range of the DDR2 SDRAM Devices. The
board has been tested with four DDR2 SDRAM devices operating at once.
• Micron Technology MT47H16M16BG – 37E
• Samsung Semiconductor K4H561638F-TCCC
Refer to the DDR2 & DDR2 SDRAM Controller Compiler User Guide for information
