Demo Batch File Folder:
DDR3x2_Test \demo_batch
The demo batch file includes following files:
Batch File: test_ub2.bat
FPGA Configure File: DDR3x2_Test .sof
Demonstration Setup
Make sure Quartus Prime is installed on your PC.
Connect the USB Blaster cable to the FPGA board and host PC. Install the USB Blaster II
driver if necessary.
Power on the FPGA board.
Execute the demo batch file “test_ub2.bat” under the batch file folder, DDR3x2_Test
\demo_batch.
Press BUTTON0 on the FPGA board to start the verification process. When BUTTON0 is
pressed, all the LEDs (LED [3:0]) should turn on. At the instant of releasing BUTTON0, LED1,
LED2, LED3 should start blinking. After approximately 5 seconds, LED1 and LED2 should
stop blinking and stay on to indicate that the DDR3 (A) and DDR3 (B) have passed the test,
respectively. Table 6-2 lists the LED indicators.
If LED3 is not blinking, it means the 50MHz clock source is not working.
If LED1 or LED2 do not start blinking after releasing BUTTON0, it indicates local_init_done
or local_cal_success of the corresponding DDR3 failed.
If LED1 or LED2 fail to remain on after 5 seconds, the corresponding DDR3 test has failed.
Press BUTTON0 again to regenerate the test control signals for a repeat test.

Many applications use a high performance RAM, such as a DDR3 SDRAM, to provide temporary
storage. In this demonstration hardware and software designs are provided to illustrate how to
