Multiple Configuration ApNote

Hi,

After seeing a number of users struggling with this issue, I have written a detailed ApNote showing how to implement a multiple configuration system for Altera FPGAs. The example is a Cyclone III using Active Serial mode / EPCS (on a DE0 board), but it is easily translatable to any other Altera FPGA or board. It is not complex, but getting everything right from the documentation is not absolutely obvious either.

The ApNote and the design files are available at the top of the list available on our website (fpga.fr, go to Tech Corner > ApNotes).

Anyone spotting a discrepancy, please let me know.

(at the bottom of the ApNotes' first page, there is a link to download the complete archive).

Hope this helps,

Bert.
