concise list of options they used, or what options are critical, or
can point me to documentation on this (other then XAPP058)? Whatever
is easy - I'm not asking for anything fancy.

Thanks!

I have used XAPP058 to get a working setup. The only thing I struggled with was getting the DONE pin to go high. I belive the code has two options for the "RUNTEST" SVF instruction (or something like that): one is a delay loop and the other puts out clocks. Make sure you pick the code that puts out the clocks. The delay loop won't work. This was for a Spartan3A FPGA.
