Is it possible for you or someone to post about how to get an 
environment up and running in Windows and/or Linux? (or link to one you 

I use xc9500xl parts with IDE 14.7 on Win10 x64 (with DLL fix) here, and 
the environment works well.  But, I have a few things that I would love 
to fix/address:

  * CPLD work goes fine with the fix, but the FPGA toolchain portions of
    ISE won't work in Windows 10, even with the DLL fix (at least for
    me).  I'd like to fix this, as some of my designs are too big for
  * Alan Hightower praises the open source toolchains and Lattice units,
    but my initial attempt to bring up a working environment here went
    down in flames. I think I need a step-by-step guide (and maybe
    someone who has time to help a poor soul get something up and running)
  * As much as I like the GUI, I want to learn how to write (or
    beg/borrow/steal) Makefile-based tooling for all my CPLD projects,
    whether Xilinx or other.

All my existing CPLD work is online: https://github.com/go4retro/ , 
warts and all.
