Hey,

I'm having some trouble building a consistently working CPLD programmer based on: http://www.xilinx.com/support/progra...es/0380507.pdf

So far I've tried making this circuit on a veroboard but the wiring gets slightly messy and this method of building is rather error and noise prone. I am currently working on a small PCB layout (using EAGLE CAD), but was wondering if someone had already gone through the trouble and wouldn't mind posting.


Thanks in advance and happy holidays!

Here on this page you can find one. It is for Xilinx FPGAs but verify your schematic with that given on the site. I guess both are same.
