Preparing for Downloading
After checking to make sure that the cables and jumpers are hooked up
properly, you are ready to download the compiled circuit to the UP2 board.
Select
To o l s
Programmer
. Click on
Hardware Setup
, select the proper
hardware, a
ByteBlasterII
on
LPT1
. (If a window comes up that displays, "
No
Hardware"
to the right of the Hardware Setup button, use the Hardware Setup
button to change currently selected hardware from "
No Hardware"
to
"
ByteBlasterII"
. If a red JTAG error message appears or the start button is not
working, close down the Programmer window and reopen it. If this still
doesn't correct the problem, then there is something else wrong with the setup
or cable connection. Go back to the beginning of this section and check each
step and connection carefully.) The new USB ByteBlaster can also be used.
Final Steps to Download
Make sure that the
Device Name
has changed to
EP10K20
or
EPF10K20RC240
for the UP1 or
EPF10K70RC240
for the UP2 (depending
on the UP board and Quartus II version that you are running). Make sure you
have also assigned the pin numbers for a UP2 board (see Table 1.1). If it does
not display the correct device, then return to your schematic, assign the correct
device first and then the pin numbers (See section 1.1.), recompile, and try
again. Next, check the
Program/Configure
box.
The
Start
button in the programming window should now be highlighted.
Click on the
Start
button to download to the UP2 board. Just a few seconds are
required to download. If download is successful, a green info successful
programmer operation message displays in the system window. (If the
Start
button is not highlighted, click
Hardware
Setup
from the programmer
window. Confirm the port settings and click
OK
. If you still have problems
confirm that the printer port BIOS settings use ECP or EPP mode.)
Testing Your Design
The locations of PB1, PB2, and the decimal LED are indicated in Figure 1.19.
On the UP2, one of the seven-segment LEDs decimal points is used for
monitoring the LED output.

's FLEX FPGA pin connection to seven-segment display decimal point.
All of these LEDs are pre-wired to the FPGA chip with a pull-up resistor as
illustrated earlier in Figure 1.6. This configuration allows the external resistor
