MapLib:979 - LUT6 symbol ERROR:MapLib:978 - LUT6 symbol

ISE 14.5,在ISE中添加microblaze,在EDK中使用两条FSL连接microblaze和自定义的IP核,edk中生成网表成功,但是在ISE中Map失败,错误如下:


ERROR:MapLib:979 - LUT6 symbol
"embed_cpu_i/fsl_v20_0/fsl_v20_0/Using_FIFO.Sync_FIFO_Gen.Use_Control.Sync_FI
FO_I1/FSL_Flag_Handle.Rd_Delay_For_Bram.fall_through_data_0_dpot" (output
signal=embed_cpu_i/fsl_v20_0/fsl_v20_0/Using_FIFO.Sync_FIFO_Gen.Use_Control.S
ync_FIFO_I1/FSL_Flag_Handle.Rd_Delay_For_Bram.fall_through_data_0_dpot) has
input signal "embed_cpu_i/fsl_v20_0_FSL_M_Control" which will be trimmed. See
Section 5 of the Map Report File for details about why the input signal will
become undriven.

ync_FIFO_I1/FSL_Flag_Handle.Rd_Delay_For_Bram.fall_through_data_0_dpot) has
an equation that uses input pin I5, which no longer has a connected signal.
Please ensure that all the pins used in the equation for this LUT have
signals that are not trimmed (see Section 5 of the Map Report File for
details on which signals were trimmed).


求解决办法,谢谢!

我也遇到了类似的问题,信号被改变是因为有未能使用的信号,检查模块定义和调用模块时的代码,发现传递的参数里有一个位数与定义的不一样

说得不对,应该根据提示信息调试,出错信息里说了,参看详细信息,找到被删除的信号然后调试
