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

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！ |
