Electrically erasable programmable logic devices (PLDs) are digital circuit components which can be programmed to perform complex logic functions. Agricultural engineering students designed circuits using PLDs and programmed and tested them as part of a class exercise in logic circuit design. The devices were erased at the end of the semester for use by the next class. Because the lab assignment required the students to master several new concepts at once, they experienced some initial difficulties; however, they enjoyed the assignment and learned the material well.
