请教: 加法器IP例化后出错.
怎么处理啊?
1)加法器例化
c_add_12int_12uint D4 (
  .clk(sys_clk),
  .sclr(rst),
  .s(pre_output_Chb),
  .a(multiplier_output),
  .b(selector_out)
  );
2)出错信息
ERROR:NgdBuild:604 - logical block 'D4/D4' with type 'c_add_12int_12uint' 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 'c_add_12int_12uint' is not supported
in target 'spartan3e'.

c_add_12int_12uint 是在同一芯片型号下用ISE 13.2 Core Generator发生的.
所选芯片型号是spartan3e 的xc3s250e-5vq100
不明白为什么"Symbol 'c_add_12int_12uint' is not supported in target 'spartan3e'."会出现.

估计是否是IP文件与项目文件没有放在同一个文件夹

Please verify that the called out netlist file is located in the macro search path or project directory.
To set the macro search path, following these steps in ISE:
1. Select the top-level source in the Source window.
2. Right-click "Implementation Process" in the Process window and select "Properties."
3. Select the "Translate Properties tab." The Macro Search Path option is available.
