Complex Programmable Logic Devices - or CPLD's, is a simple but powerfull technology, that can be used to implment complex digital circuits in a single IC package. A single CPLD can replace all the traditional CMOS/TTL IC's in most designs, making the CPLD a very powerfull component when designing digital systems. As CPLD's are reprogrammable, replacing traditional CMOS/TTL packages (e.g. 74.. series IC's), with a CPLD has the following advantages:
As many students do not have direct practical experience with CPLD's, many student designs still incorporate classic CMOS/TTL logic IC's, as the 74LS, 74F, 74HC, 74HCT or 40 series IC's, although this approach is deeply obsolete.
In order to reduce the barrier towards using CPLD's in students projects, I have designed a simpel demo/prototype board, that will allow students to experiment with CPLD's and test out their designs using CPLD's rather than obsolete logic IC's.
The CPLD demo board have the following features:
The PCB and PCB documentation is available, but I have not yet managed to write a users guide.
