关于system generator中edk的使用问题

2012/9/24镜像同步1 回复

大家好，我在system generator电路中需要用到edk模块。我先建了一个xps工程，生成了网表和bit文件。之后在system generator导入了这个模块，并添加了shared memory。随后我又打开xps工程，发现可以生成网表却不能再生成bit文件了。显示的错误信息也让我觉得很困惑，如下面所示。有没有人遇到过同样的情况，还请不吝赐教。 ERROR:MapLib:978 - LUT3 symbol "microblaze_0/microblaze_0/MicroBlaze_Core_I/Performance.read_data_mux_I/WB_DataBus_Read_Data<8>1" (output signal=microblaze_0/microblaze_0/MicroBlaze_Core_I/Performance.wb_databus_rea d_data<23>) has an equation that uses input pin I1, which no longer has a connected signal.
