EPF10k10 reconfiguration

Hi! What's the best way to perform a reset / reconfiguration on the EPF10k10? Looking at the configuration appnote (AN59, page 4) I'm guessing it's as simple as pulling down nConfig which would...

Using nCONFIG is overkill though, since it forces reconfiguration of the FPGA. If you have any external devices relying on the FPGA I/Os being in a specific state, then since the I/Os will tri-state (or pull-up) during reconfiguration, you'd have to be careful about having pull-downs on any signals that needed them.

If all you want is a reset, then you can just use a reset input (ideally routed to a global input pin on the FLEX10K series).

However, overkill maybe what you're after ... :)
