    I mentioned to Dave that the article in the latest Xcell issue 84 titled "XRadio" on page 28 is a Spartan-6 all-digital FM radio that uses an input-pin as a cheap 1-bit ADC.
    Note this is NOT the same as what Dave did since it does not use feedback like a Sigma-Delta converter does.
    But I do feel that Dave could use an LVDS input-pin config (instead of single-ended CMOS) and get much better performance (and perhaps the integrated feedback output could drive the inverting input of the LVDS, though it would then be limited by the common-mode input range).
    Conversely, I also wonder if that XRadio could change to a Sigma-Delta ADC scheme (with a much-higher oversample-rate) and get better fidelity.

    Not to focus on only Xilinx FPGAs, but I just wanted to point-out there is a Xilinx quarterly "Xcell Journal" at:
    You can also subscribe to get new issue notifications via email.

    You'll find articles on things that were briefly mentioned last nite such as Xilinx' new 3D-stack technology and their Zynq SoC (FPGA with embedded ARM Cortex-A9).
    Xcell sometimes tends to be a glossy-production magazine with a lot of "look what we did" marketing articles and ads, but it still might be worth checking out every three months.

    It has been long time since coded any HDL. Dave's session is refreshing me instantly on all those that I have been missing. nostalgic :) . learned a lot of new stuff as well, especially the free tools that are out for us. As usual the meetup was very interactive, that's our strength indeed.

    David did a great job presenting FPGA hardware & software tools in a way that really encouraged experimentation. He didn't pull any punches about there being steep learning curves "ahead". He hinted that people who didn't have a good grasp of digital electronics needed to time-travel back and take some course-work, then time-jump return to the present. I'm sure I saw a couple of folks blip out, and back.
