The design files for the factory design are installed from the DSP
Development Kit, Cyclone II Edition Version 6.0.1 CD-ROM
in the
directory:

<path>\CycloneII_DSP_Kit-v6.0.1\Examples\
FactoryDesign_ChA

Testing LEDs & Pushbutton Switches

In the factory design, switches SW2 through SW5 (

USER_PB3 through

USER_PB0) are connected via inverters to LEDs D9 through D6
(

USER_LED0 to USER_LED3, respectively). When a switch is pressed, the

corresponding LED turns off. You can test this functionality on the
Cyclone II DSP development board.

Performing the A/D & D/A Converter Performance Test

To test the A/D and D/A converter performance using the factory
design, follow these steps:

1.

“Configuring the Board” on page 2–17

2.

“Collecting Data Using the SignalTap II Logic Analyzer” on
page 2–20

3.

“Analyzing the Data in the MATLAB Software” on page 2–20
