请版主或路过的高手赐教: 我在nios的cpu里添加了自定义指令模块并读出了port ,也已经Add to system,重新生成系统后在编译时,出现错误: Error: Port "D_ci_a" does not exist in macrofunction "the_cpu_0" Error: Port "D_ci_b" does not exist in macrofunction "the_cpu_0" Error: Port "D_ci_c" does not exist in macrofunction "the_cpu_0" Error: Port "D_ci_n" does not exist in macrofunction "the_cpu_0" Error: Port "D_ci_readra" does not exist in macrofunction "the_cpu_0" Error: Port "D_ci_readrb" does not exist in macrofunction "the_cpu_0" Error: Port "D_ci_writerc" does not exist in macrofunction "the_cpu_0" 。。 请问是什么原因呢?谢谢!
