解決方案：官方給出的解決方案是忽略warning，對(duì)結(jié)果不影響。

(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

解決辦法：在XPS的project菜單欄選擇project options中選擇hierarchy and Flow將Treating

timing closure failure as an error前面的√去掉即可。

(7).ERROR:Place:713 - IOB component fpga_0_DDR2_SDRAM_DDR2_DQ13> and

into

the same I/O tile in order to route net

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

where we must place IODELAY

n_dq[13].u_iob_dq/u_idelay_dq in order to satisfy the relative

requirements of this logic. IODELAY

n_dqs[0].u_iob_dqs/u_iodelay_dq_ce appears to already be placed there

which

makes this design unplaceable.

解決辦法：打開(kāi)你的工程，在system assembly view的界面下，切換到ports欄下，將fpga_0_DDR2_SDRAM的下拉框中，找到相應(yīng)的的項(xiàng)，選中相應(yīng)的項(xiàng)就可以。
