解决方案：官方给出的解决方案是忽略warning，对结果不影响。

（6）.ERROR: 1 constraint not met.

PAR could not meet all timing constraints. A bitstream will not be generated.

To disable the PAR timing check:

1> Disable the "Treat timing closure failure as error" option from the Project Options dialog in XPS.

OR

2> Type following at the XPS prompt:
XPS% xset enable_par_timing_error 0
解决办法：在XPS的project菜单栏选择project options中选择hierarchy and Flow将Treating
timing closure failure as an error前面的√去掉即可。

makes this design unplaceable.
解决办法：打开你的工程，在system assembly view的界面下，切换到ports栏下，将fpga_0_DDR2_SDRAM的下拉框中，找到相应的的项，选中相应的项就可以。
