各位原子老师，求解ISE 使用ILA出现的报错

CJC529

CJC529

建议少使用ILA的方式在ISE中，使用网表的方式创建cdc文件，进行ChipScope仿真测试，设计流程参考https://www.cnblogs.com/liujingg ... %E7%9A%84T%E6%A0%87,%E5%B0%BA%E6%9D%A5%E7%9B%B4%E6%8E%A5%E5%BE%97%E5%87%BA%E7%BB%93%E6%9E%9C

ERROR:NgdBuild:76 - File "ipcore_dir/sb_ila.ngc" cannot be merged into block
   "u_sb_ila" (TYPE="sb_ila") because one or more pins on the block, including
   pin "TRIG0", were not found in the file.  Please make sure that all pins on
   the instantiated component match pins in the lower-level design block
   (irrespective of case).  If there are bussed pins on this block, make sure
   that the upper-level and lower-level netlists use the same bus-naming
   convention.
ERROR:NgdBuild:604 - logical block 'u_sb_ila' with type 'sb_ila' could not be
   resolved. A pin name misspelling can cause this, a missing edif or ngc file,
   case mismatch between the block name and the edif or ngc file name, or the
   misspelling of a type name. Symbol 'sb_ila' is not supported in target
   'virtex4'.
