Post subject: | Best CPLDs & toolchain for beginners |
I want to get into CPLDs (and later FPGAs) but am finding getting going to be difficult. Initially I’d like to tackle address decoding. I thought I might start with the ATF15xx. But what toolchains do people recommend? I’m platform agnostic (ie, Windows, Linux and Mac all work for me - I’d probably draw the line at System/360). Are there other CPLDs that are good for beginners (eg, well supported with software)? I’d prefer to go with chips that are still in production. |

If you're interested in the Microchip (Atmel) ATF parts—which are in current production—you can snag a copy of WinCUPL from their site to do you development and simulation. WinCUPL runs on any version of Window$ from 2000 onward. The package is a bit buggy here and there, but does work. If you have any trouble getting hold of the software please contact me via PM and I'll try to help. |

Thanks. I've now got WinCUPL installed. It's kinda ... um ... early 1990s, but I guess it does the job. |

I'm going to jump in with a question: What if I'm NOT platform agnostic? I see that WinCUPL is Windows (only?) and I'm a Linux guy. Though Windows might be possible, it's not preferable. Likewise Wine has not been my best friend in the past. Any thoughts on Linux based CPLD/FPGA programming for beginners like me? I'm currently using Quartus 13.0sp1 with EPM7128S CPLD's. I like it well enough, so just asking around. Thanks! Chad |

Chad You can try the Lattice Diamond package... if you want to stick to Lattice devices... and Red Hat Linux... and version 6.9 or 7.4.... and the 64-bit version. Some people seems to run it under Ubuntu, and I think I tried it a few years ago. It might not be a good idea, but the package is free and has a simulator bundled with it (at least under windows). |
