Q^6.1 Fitter dies

Has anybody else noticed that Q6.1 Fitter dies at 96% and the only thing that will continue is the time counter ? dual cpu load is at about 1-2% ... idle.

the last messages within the processing window are :

Info : Fitter routing operations ending

Info : The fitter performed an Auto Fit ....

Info : Started post-fitting delay anotation

Warning : Found .... output pins without output pin load capacitance assignment

shuting down q6.1 and restart and q6.1 will compile fine .....

This happend now and then ... but not very often.

Michael

PS: Q6.1 need about 2/3 of the full compile time than Q6.0 with 2 cpu cores. Thanks Altera

    I too was seeing this on a dual core machine. I haven't been able to reproduce it in a while to figure out what is causing it.

    Can you please email a brief system description of your system (processor, memory, and OS).

    Shure.

    It is a Dell Optiplex GX620 (it is a very silent but incredible fast system)

    Thanks for the information. If I learn anything new about this one I'll post it in here.

    just some more comments about it.

    this behavioral of a dieing Q6.1 is not related to a specific design. it happens here will ALL designs. it happens every now and then. but always at 96%.

    but i haven't seen it if i set the number of cores to 1.

    we have another P4 server with HT or real dual core (not shure at the moment). today i will start some complete compiles there and see if it happens there too.

    With MaxII designs, it happens that Q6.1 reports at 81% of the Fitter :

    Internal Error: Sub-system: FMAIN, File: /quartus/fitter/fmain/fmain_location_constraint.cpp, Line: 3024

    m_soft_locked_constraint.check_constraint( other_constraint->m_soft_locked_constraint)

    Intresting that MaxII freezes at 81% .... if it freezes.

    are there any new experiences regarding this topic - is there a way to avoid this fitter locking ?

    (it just happened three times in a row now ...)

    thanks

    Hi Stonie,

    there is currently only one solution known to me ...

    just set max number of processors allowed back to 1.

    But most of the time the fitter runs fine with more than 1.

    So if your fitter dies too, just set this setting back to 1 re-run the fitter and after a successfull job, set it back und run with all processors you have.

    2 processors saves about 30% of the overall fitting time here.

    This week i had asked mysupport if a fix for this problem is available bevor the next service pack. As i had noticed this beginning of december and thought that now 2 months later a fix could be available.

    but this is the answer of mysupport :

    "Unfortunately, we don’t have such a fix since we didn’t receive similar issue report before." http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif

    Does this mean nobody has reported this to mysupport ? Well i havn&#39;t. But does mysupport not read this forum ?

    I hope Altera is aware of this issue and has a fix that will be available soon.
