Power on the DE0-CV board with the USB cable connected to the USB-Blaster port. If necessary
(that is, if the default factory configuration is not currently stored in the EPCS device), download
the bit stream to the board via JTAG interface.
You should now be able to observe the 7-segment displays are showing a sequence of characters,
and the red LEDs are blinking.
Press FPGA_RESET to make LEDs and 7 SEGs all light on.
If the VGA D-SUB connector is connected to a VGA display, it would show a color picture.

Configuring the EPCS64 in AS Mode
1.
Ensure that power is applied to the DE0_CV board.
2.
Connect
the supplied USB cable to the USB Blaster port on the DE0-CV board
3.
Configure the JTAG programming circuit by setting the RUN/PROG slide switch (SW10) to
the PROG position.
4.
Execute the demo batch file “pof_DE0_CV_Default.bat” for USB-Blaster under the batch
file folder, DE0_CV_Default /demo_batch.
5.
Once the programming operation is finished, set the RUN/PROG slide switch back to the
RUN position and then reset the board by turning the power switch off and back on; this
action causes the new configuration data in the EPCS64 device to be loaded into the FPGA
chip.
Configuring the EPCS64 with .JIC File
1.
Ensure that power is applied to the DE0_CV board.
2.
Connect
the supplied USB cable to the USB Blaster port on the DE0-CV board.
3.
Exe
cute the demo batch file “ DE0_CV_Default.bat” for USB-Blaster under the batch file
folder, DE0_CV_Default /demo_batch.
4.
As
shown in
Figure 5-1
,
It is able to not only load the bit stream into the FPGA in command
line, but also program or erase .jic file to the EPCS by executing the batch file.
5.
If users
want to program a new design into the EPCS device, an easy method is to copy the
new .sof file (file name must be DE0_CV_Default.sof) into the demo_batch folder and
execute the DE0_CV_Default.bat. Option “2” will convert the .sof to .jic and option”3” will
program .jic file into the EPCS device.
