问:如何使能stratixii的extended lut mode

gowa

我使用的是stratix ii 器件。synplify 8.1综合结果.vqm网表里面有7输入的LUT，然后Quaruts分析网表的时候报错:Error: WYSIWYG LCELL COMB primitive "I_18865_1" cannot use datag port -- datag port must be used only in extended LUT mode
wysiwyg我是打开的。
查原因它说
CAUSE:The specified WYSIWYG LCELL COMB primitive is not in extended LUT mode (that is, the EXTENDED_LUT parameter is set to OFF), but uses the datag LUT input port. The datag port must be used only in extended LUT mode. Either the EXTENDED_LUT parameter must be set to ON, or the datag port must be disconnected.
但是我不知道如何打开EXTENDED_LUT ，直接在脚本里面添加一句
set_parameter -name "EXTENDED_LUT " ON
结果还是报错。咋办?
