Re: [partial-reconfig] Problem with partial bitstream

["Lakshmi Narasimhan. S" <sulakshm@xxxxxxxxxxxxxxxxxxxx>]

Hello Team,
After reinstalling my ISE to 6.3i and not updating it to 6.3.03i
I have successfully tested my first dynamic partial reconfiguration
on the board. No changes with the flow, just it works as earlier.

A great relief... now I can think ahead.

But my earlier question still remains. Can anyone tell me
how you are mapping the pins for ml310 board which has more
inputs than clock and more outputs than leds?

This will help me out on designs with more than clocks and leds
as my ports. I am really stuck on this now.

Thanks
LN
