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 ...
