has some small Altera and Xilinx CPLDs in the $3 to $12 range but you could struggle to fit a complex design into these devices. However there are a few barriers to getting started, some of them lower than others:Ĭost - most CPLD and FPGA devices are relatively expensive in small volume, especially large, modern FPGAs. Both companies offer free development suites for download which are a good way to get started, but be warned! I think they weigh in at over 1GB each. The devices they offer perform essentially the same functions at a higher level but are fundamentally different in their internal structure. The two biggest manufacturers are Xilinx and Altera. ![]() It is entirely feasible to implement the entire Arduino boad, USB interface and all, inside a single FPGA. They are very useful things for implementing your own simple custom logic up to more complex things like DSPs, ethernet MACs, digital filters etc. I have a lot of experience with FPGAs and CPLDs.
