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。

Some of the logic associated with this structure is locked. This should
cause
the rest of the logic to be locked.A problem was found at site

which
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。
