convert avalon bus to AXI4-Lite

@RichardTanSY_Altera

Thank you!

I have many questions to use Cyclone 10 LP 10CL120.

My company buy the FPGA, and produce the PCB board. however, we can't power on it.

For example, my questions are:

1) whether we should connect a crystal oscilator to which pin of FPGA.

2) how to use Quartus to constrain signal node to GPIO pins.

3) I would like to run NIOS II in FPGA, however I don't know how to enable burning firmware interface.

4) and etc.

Our product previously used ZYNQ7000 of Xilinx, but Now, we are going to use Cyclone10LP.

Would you please contact me by my email: dpstill@126.com.

By the way, I previously worked in Intel as well.
