When recompile the programs written by Quartus II 9.1 with Quartus II 13.0 and programme the new POF file into the FPGA(EP1C12), I find that the FPGA does not work the same as being programmed with the POF file produced by Quartus II 9.1. So I wonder whether the POF file produced by Quartus II 13.0 is wrong. Are something of compiler of Quartus II 13.0 should be set up before recompiling programs written by Quartus II 9.1? Or 13.0 and 9.1 are not Compatible? Looking forward to your help!
