LED diode as indicator that FPGA works

Hi, 

 

I want to put some led diode as indicator that my FPGA works fine ( I use ARRIA II GX ). Is there a pin I can use as indication that my component works and in user mode ?  

 

PS -- I use JTAG configuration . 

 

Thanks...

Look up the CONF_DONE or INIT_DONE pins in the handbook. 

IIRC, these are dual purpose pins, which can otherwise be used as regular I/Os.

I know ,  

 

But I do I put there LED so that it will "light" when the FPGA works when 

it is already connected to resistor and VCCIO , and those pins are driven high  

when the device ( === > no current passing) is on ? 

 

Thanks for your quick reply ...
