ZYNQ 7020 Learning experience "1"

Today control Miz702 Board, learned the use of Emio, encountered a little problem, after analysis and try, solved, write, for everyone reference.

The first problem is that the constraint file is warning and generates bitstream error.

The constraint file format given in the Development Board tutorial is as follows,

After analysis and attempt, it is found that the {} symbol is not supported after get_ports, it may be caused by my Vivado2015.3 (2015.4 in the tutorial), this is only speculation, not verified, if a friend knows, please tell.

After the {} is removed, the integration and implementation succeeds.
