How to deal with time limited build

I have a De1 SoC board which in the example code apparently includes time limited IP so I can program the board and do things when connected, but the example says to convert the .sof file to an .rbf file, which I cannot do. Not only that, for my testing I need the system to boot, load the FPGA image, and the software to see if it will run. Since this doesn't seem to be supported by the tools you offer, I will have to find an Alternative solution. The Pro version of your tools doesn't support the cyclone V device, and there doesn't seem to be a way to buy a license for the IP modules. So if there is no solution, I will have to abandon using Intel FPGAs. Lee
