3. Using the Control Panel
Overview
The control panel consists of the following:
■The graphical user interface (GUI) application on the host computer
■The standard Nios II hardware design running on the board's
Cyclone III FPGA device
After installing the Cyclone III FPGA Starter Kit, you can locate the
control panel for the hardware and software in the
<kit path>\demos\control_panel directory.
The design downloaded to the Cyclone III device implements a
command controller that processes board commands sent over the
USB-Blaster from the control panel. To perform the appropriate actions,
the command controller communicates with the controller of the targeted
board I/O device.
You can perform the following actions with the control panel:
■Light up LEDs
■Detect push button presses
■Read from and write to the DDR SDRAM, SRAM, flash memory, and
on-chip RAM
The following sections describe how to perform the above actions with
the control panel already open on the host computer. If not already open,
launch the control panel as described in “Control Panel Start”.

The common flash interface (CFI) flash memory devices conform to basic
flash commands. The most basic command is Query which switches the
device into a ROM table mode so that features of the flash device are
determined by reading values from the table.
To perform a CFI query using the host application, click CFI Query.
Notice that the memory table displays contents that correlate with the
table contents as described in the device datasheet.

One of the main features of the Cyclone®III device is its low power
consumption. You can measure the power of the 3C25 device on the
Cyclone III starter board under various conditions with an example
design provided with the kit.
The power example design allows you to control the amount of logic
utilized in the FPGA, the clock frequency, the number of I/Os being used,
and measure the effect on the power to the Cyclone III device. Because the
Cyclone III starter board has only four buttons and four LEDs, interaction
with the board is minimal as defined below.

the power example design.

The design used for power measurement is a replicated set of randomly
filled ROMs that feed a multiplier block and a shift register that is fed by
a signal that changes every clock cycle. Ta bl e s 4– 2 and 4–3 show the
power state which represent the percent of the full design used. As
compiled, this full design uses:
The example design is located in
<kit install>\examples\cycloneIII_3c25_start_power_demo. Configure
the FPGA with the .sof found in the directory.
1The input clock (i_clk PIN_B9) is the 50-MHz oscillator on the
board, which generates the input clock for the reference design
through a PLL
fFor more information on configuring the FPGA, refer to “Configuring
the FPGA Using the Quartus II Programmer” on page 2–3.
Current sense resistors (0.010 ± 1%) are installed at locations JP6 (FPGA
core power) and JP3 (FPGA I/O power + other device I/O power). With
a digital multimeter set to mV measurement range, the resistor at location
JP6 measures the core power. The resistor at location JP3 measures the
I/O power. To measure the current being used in various configurations,
use the following steps:
4–2Altera Corporation
Cyclone III FPGA Starter Kit User GuideJuly 2010
Measuring Power on the Cyclone III Starter Board
1To obtain the power (P) in milliwatts, measure <Measured
Vol ta ge > (the voltage across the sense resistors at JP6 or JP3) in
mV and calculate the nominal power using the equation:
P = 100 x <Measured Voltage> x <Supply Voltage>
where <Supply Voltage> is 1.2 V for JP6 and 2.5 V for JP3.
You can use the four input buttons to advance through the various power
state as outlined in Table 4–2. Notice how current increases as frequency
and resource usage increase.
You can also measure the I/O power consumed by measuring the voltage
across sense-resistor JP3 when Button 4 is pressed and held. Because this
2.5-V power rail is shared with other devices, there is a nominal 100 mW
that must be subtracted from the calculated I/O power to obtain the
FPGA I/O power.
The number of I/O pins used is controlled by the resource state (shown
in Tables 4–2 and 4–3). For each increment in resources, 16 additional I/O
pins are added (refer to Table 4–4).
Table 4–4. I/O Pin & Resource State
LED4/LED3Number of I/O Pins
0016
0132
1048
1164
Similarly, the toggle-frequency of these I/O pins is set by the overall
design frequency (refer to Tab l e 4– 1).
Changing the Example Design
The source code for the Cyclone III power example design is also
provided so you can use it as a starting point for your own measurements.
You can adjust the number of outputs by changing parameter
NUM_OUTPUTS_PER_STAMP. The default is 16, which for four resource
percentage steps equates to 16 x 4 = 64.
The appropriate pins to be used as outputs are pre-assigned to the HSMC
connector (J1). If you would like to look at more than the 76 I/Os available
on J1, you need to make the appropriate pin assignments.

Overview

FlashProgrammable
POF File
Figure A–1. Convert Programming Files Window
The Intel® P30 flash device uses active parallel flash configuration to
configure the Cyclone®III device on power up. The Cyclone III Starter
Board has a factory default configuration programmed into the P30 flash;
however, after developing your own project, you may want to replace this
factory default configuration with your own. This appendix describes
how to reprogram the Intel P30 flash device.
After a Quartus II compilation, a Programmer Object File (.pof) is created.
Before you can program this file into the Intel P30 flash device on the
Cyclone III development board, you must modify the .pof by performing
the following steps:
1.Choose Convert Programming File from the File menu. The
Convert Programming Files window opens (refer to Figure A–1).
Altera Corporation A–1
July 2010Cyclone III FPGA Starter Kit User Guide
9.Click Generate. If you are overwriting the input .pof you will
receive a warning asking if you want to overwrite it. Click Yes to
overwrite the file or enter a different filename. When the Quartus II
software finishes converting the file, you can use the converted .pof
to program the on-board parallel flash device.
1The Quartus II software also generates a MAP file, which
can help you debug issues with locations in the flash device.
A–4Altera Corporation
Cyclone III FPGA Starter Kit User GuideJuly 2010
Programming
the Flash Device
Altera recommends that you do not overwrite the factory hardware and
factory software images unless you are an expert with the Altera tools or
deliberately overwriting the factory design. If you unintentionally
overwrite the factory image, perform these flash programming
instructions using the cycloneIII_3c25_start_niosII_standard.pof found
in the factory_recovery directory for the object file in step 9.
To program the flash device, follow these steps:
1.Open the Quartus II Programmer.
2.Click Auto Detect from the button list to the left of the
programming file list area.
5.Turn on the Flash Memory and CFI_128MB options (refer to
Figure A–5).

hardware into the FPGA, which allows the Programmer to
communicate with the flash device. The Programmer sends the .pof
to the flash device via the flash programming hardware. The
Quartus II Message window displays the bank addresses as they are
erased and then written.
12. To configure the Cyclone III 3C25 with your design from the
on-board flash device, either push the reconfiguration button or
turn the Cyclone III Starter Board off and then on again.
