The Lattice parts are nice too, e.g. the MachXO2: Powerful as a small Altera Cyclone (PLL, hardware multiplier etc.), but with integrated flash, like for CPLDs, and available down to WLCSP packages (that's 2.5mm^2).

I was lucky enough to get one of these boards for cheap:
http://www.embeddedarm.com/products/board-detail.php?product=TS-7300

Arm 9, CPLD, FPGA all on the same board with pinouts, sd card slots and more.
You boot off the sdcard into ARM Linux and then just use console commands to load and control the CPLD and FPGA.  Makes development easy, no extra hardware required.You can even connect a keyboard and monitor and use the board to write the code for the FPGA .

Looks good. The ARM CPU is a bit slow for todays standards, but a high speed bus between the CPU and the FPGA can be used for many interesting applications. I can't wait to get my Parallela board.

Big additional thumbs up for FPGA videos...

I really love Dave's videos, but I have noticed that maybe as the blog has become more popular, there is more teardowns, equipment reviews, mailbag, etc.  And there have been less videos which might appeal to real engineers and designers.  This is not a criticism at all - Dave should do what sells of course :)  but as for me, I would LOVE to see not only some FPGA videos, but it would be fantastic to see a few episodes about actually making something tangible... not just some example project blinking an LED, but a real project... similar to the Mu Current, or the USB power supply, or the exterior LED patio lighting.  Something we can follow along with and see it being done... I miss those kinds of videos.
It's not always the most popular person who gets the job done.

This reminds me, I stilll haven't send my packet to Dave. Like year and half gone since I got the idea, well. Perhaps before Xmas.

See a little sample of something I made here:

http://codyshaw.ca/2012/06/02/8-bit-adder-update/

Nice. I don't know much Verilog, can you do loops with it to avoid instantiating every single one bit adder by hand? Would be worse for a 32 bit adder.

Here is a 4 bit multiplier I created when I learned VHDL:

See the "generate" loops, which would make it easy to implement a 32 bit multiplier without more code (but very many gates, because it is all static and parallel).

I created a 4 bit multiplier in VHDL as well. I'll have to dig up the code.


I was messing around a bit with some small capacity devices from both Xilinx and Altera. I do have a DE0 Nano so I guess I'll have to bust it out of it's box and join the fun. I'm sure I have some interesting code around.
