Quartus II Internal error

Hello All,

When I tried to compile a verilog code written for EPM7128STC100-15(MAX7000S family), it gives an error message as given below after completing almost 80% of Analysis & Synthesis phase. I dont know which part of the code generates this error.

"Error Message: Internal Error: Sub-system: MTM, File: /quartus/synth/mtm/mtm_auto_global.cpp, Line: 188"

BTW, I use Quartus 9.1 version.

Any ideas about the possbile cause of this error?

Thanks,

Renjith

    Contact MySupport and report this error

    maybe you can try a newer version of quartus to see if this problem still exists or might be fixed

    Thanks for the reply MSchmitt.

    Atlast I found the cause for the issue.

    After adding the symbol to the .bdf file, I was trying to compile without generating pins by "Generate pins for symbol ports" option.

    Once I generated the pins, the compilation completed successfully without showing any error.

    It was my bad but it would have been better if the Quartus had shown any suitable compilation error instead of the verbose internal error.

    Leaving this reply here as it would be helpful for someone who comeacross the same error.

    Regards,
