How to get rid of the limited display on this board

I ordered a xilinx zynq single board computer , the Z-turn board, But I find it has limitation on display, I asked their engineers and they told me that this board is using xylon trial version IP and can only work within 30 minutes after booted, I need to buy the license of the IP core, but I think the license price is pretty high, is it possible to develop the IP core by myself? Any good suggestions?
