之前用modelsim编写了2选1多路器,并且仿真成功。但在用quartus时在编译过程中遇到如下错误:
Error: Can't compile duplicate declarations of entity "muxtop_top" into library "work"
Error: Instance could be entity "muxtop_top" in file muxtop_top.v
Error: Instance could be entity "muxtop_top" in file muxtop_top.bdf
library我在之前就定义为RTLsim了,不明白它什么意思?谢谢高手
