gem5报错

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "build/X86/python/m5/main.py", line 457, in main
    exec(filecode, scope)
  File "configs/tutorial/two_level.py", line 37, in <module>
    system.cpu.icache = L1ICache(options)
  File "build/X86/python/m5/SimObject.py", line 1281, in __getattr__
    raise AttributeError(err_string)
AttributeError: object 'System' has no attribute 'cpu'
  (C++ object is not yet constructed, so wrapped C++ methods are unavailable.)

原因

建立cpu不小心放在cpu.icache后面了

解决办法

移到前面去即可
