Once the Project File is created, the next step is to add the design source file(s) into the
user’s project. For this tutorial, a single CUPL design file will be added into the project.
1. Click on the ADD/EDIT button from Source Manager to open the Source Man-
2. In the Source Manager Window , click on the ADD button to add a CUPL design
3. In the File Manager Window , select LOGIC_D8.PLD from the
This "LOGIC_D8.PLD" is a CUPL design that uses the eight 8-segment LED displays
and the 2 MHz oscillator on the Atmel CPLD Development/Programmer Board to gener-
ate a scrolling message that displays the words "logic doubling" on the LEDs. The GOE
push-button switch is used to control the direction that the message scrolls in (left or
right). The GCLR push-button switch is used to reset the counter registers. When the
GCLR push-button switch is depressed, the message will stop scrolling. This CUPL
design can be compiled using either the ProChip Designer or the Atmel-WinCUPL
software.
The first section of the LOGIC_D8.PLD as shown below pre-defines which segments of
the LED should be asserted in order to display the desired letter or number. For exam-
ple, to display the upper case letter "C", segments A, D, E, and F need to be set to low
(active low) and the remaining segments need to be set to high.
