新接触FPGA SOC，买的是友晶DE1的板子，系统是WIN7 X64，安装了Quartus primer 17，和SOCEDS 、DS-5，运行培训教材的图形读取例子demo1_axi，遇到以下问题：
Error (210039): File D:/test/demo1_axi/hardware/DE1_SOC_golden_top_time_limited.sof contains one or more time-limited megafunctions that support the Intel FPGA IP Evaluation Mode feature that will not work after the hardware evaluation time expires. Refer to the Messages window for evaluation time details.
另外：请指导下学习的路径，比如书和开发板以及进阶的过程，谢谢！
