fpga pins are deactivated

I have been developing an IP and it was working just fine until I used it in a project.

After that two of fpga's output pins didn't work at all ! After some investigations I just realized that, in design summary these two pins reported under reg(s), valued ''off''. I think that somehow these two pins switched off.

Can anyone tell me how can I switch a pin off and on, and what makes it behave that way?

These pins are doing a simple job just turning a led on and off and they are working fine when I am testing IP, and just in the bigger project switched off.

The "OFF" in Reg (s) column doesn't mean that pin is turned off.

It means that the IOB is configured to use "Output Flip Flop" :)

Other modes might include IFF, ODDR, ENFF, etc.
