8   Limitations

8.1   Limitations of the Simulated Model

• The following UltraSPARC registers are not implemented:
  • The ECC error registers.
  • Cache diagnostic registers.
  • Performance control registers, and counters.
• Simics does not run the real POST, and as a result system management such as dynamic reconfiguration is not supported.
• System reset is not supported.
• Multi-machine configurations with graphical consoles do not work on Windows hosts since it uses SDL that only supports one window.

8.2   Other Limitations

• The Solaris version of SimicsFS does not support truncating files.
