Want to try CPLD devices? It is good to start with development board for that. Here it is – a nicely made XC9572XL CPLD development board.
Development board has all I/O ports available. For quick prototyping there are six 7 segment LED indicators connected, also there are 8 LEDs connected via ULN2003A. Board is also equipped with two non symmetrical adjustable RC oscillators based on 74AC04 IC and two hybrid oscillators, piezo sounder and more. Available files for download: circuit, and operating video sample. This source may be a good start for developing your own CPLD board.
