how to add hex file into design file to compile

thank you both for replying. I was able to add the hex file into the project and was able to compile without errors. I can see the hex file added in the project navigator, but it seems like even after I compile I'm getting the same checksum in the output (.pof) file as if the hex file is not there. I added the hex file using Project => Add Filename and point to where the file is stored at. Could it be that the hex file name is not matching the name that is hard code somewhere in the HDL file?
