  1. Flavia: the Free Logic Array

    Flavia, the Free Logic Array, is a programmable device intended primarily as a teaching tool for FPGAs and CPLDs. Unlike every commercial device I'm aware of, Flavia's tool suite is free-as-in-liberty open-source software (FLOSS). This means it can run on platforms other than x86 PCs, including Raspberry Pi (tested) and BeagleBoard/Bone (not fully tested yet). Flavia is a "CPLD in an FPGA", which uses FPGA look-up tables (LUTs) to implement both logic and routing. Since Xilinx documents ways to find the locations of your LUTs and flip-flops in their otherwise undocumented bitstreams, it's possible to program those LUTs to make a reasonably nice CPLD that can be programmed using FLOSS tools. Flavia's first implementation uses the Papilio One 250K as its underlying FPGA. The 250K Spartan-3E FPGA has enough logic resources to make a useful CPLD and the FT2232D provides an easy programming interface for Flavia's software. If you're interested, take a look at my 'blog at element14, which has links to all the software and documentation. This post has been promoted to an article
