[Kodera2t] wanted to experiment with programmable logic. Instead of going with an FPGA board, he decided to build his own CPLD (complex programmable logic device) board, with a built-in programmer.

Over on the University of Reddit there’s a course for learning all about FPGAs and CPLDs. It’s just an introduction to digital logic, but with a teacher capable of building a CPLD motor control board ...

These programmable-logic devices combine CPLD flash configurability with an FPGA lookup-table architecture for lower-cost, logic-intensive designs. Applications traditionally supported by high-density ...
