altera 器件仿真问题，请指教

我用modelsim做后仿真，我用的是altera cyclone的器件，在load的时候出现如下：

我得cyclone库已经编译通过了，sdf文件出现了问题，请问是怎么回事啊？
Error/program/demod_ver/simulation/modelsim/demod_ver_v.sdo(41): Failed to find INSTANCE '/tbtime/clk18m~I/asynch_inst'.
好像时没找到instance，但是我查看了sdo文件，下面时41行内容
，但是这个instance就是cyclone_asynch_io，比如41行如下
40  (CELL
41    (CELLTYPE "cyclone_asynch_io" )
42    (INSTANCE clk18m\~I.asynch_inst )
43    (DELAY
44      (ABSOLUTE
45        (IOPATH padio combout (1130:1130:1130) (1130:1130:1130) )
46      )
47    )
48  )
而cyclone_asynch_io我已经编译过了，怎么会出问题那？

我也遇到类似问题，楼主问题解决了么？
或者大家指点一下！谢谢了。

好像是没有设好apply to region这一项
