Quartus II v9.1 internal error

When I compiled a project, an internal error was found, just like below:

Internal Error: Sub-system: CUT, File: /quartus/db/cut/cut_pll_util.cpp, Line: 7954

Unexpected PLL type

Stack Trace:

0x965a: fmain_start + 0x83a (FITTER_FMAIN)

0x9702: MEM_SEGMENT_INTERNAL::locked_allocate + 0x62 (ccl_mem)

0x82c5: MEM_SEGMENT_INTERNAL::allocate + 0x95 (ccl_mem)

End-trace

Quartus II Version 9.1 Build 222 10/21/2009 SJ Full Version

Can someone help me?

    You may want to file a support request, because even a faulty PLL configuration (assuming the problem is actually related to PLL) shouldn't cause an internal error.

    In the meantime, you should try to find out, if something in your PLL setup is wrong or at least unexpected by Quartus.

    It seems quartus ii errors in handling PLLs.

    There are two plls in my project. Quartus ii seems trying to merge them.

    The types of two pll are setting to 'Auto'.

    When set to left_right pll or top_bottom pll, the problem can be solved.
