I created a new project in xDX Designer and then I open xDX IOPT. I added a FPGA device in xDX IOPT then I assign some signals to FPGA pins and leave other FPGA pins un-assigned. I generate FPGA symbol using Tools => Symbol Generator and also Update Power Pins under Tools before generating symbol. But when I click ECO > Forward Annotate to Schematic I do not see the lights turn on at the right bottom corner of the attached image. I guess I am missing something. I would like to Forward Annotate the FPGA symbol to Schematic i.e. xDX Designer. Please have a look in attachment.
