problem about set profile

redrabbit

hi all,

     recently , i ve been working on enhancing the performance for my verfication enviroment,i config "set profile" in setup().

the same seed ,same stimuli,but the results are different.

sometimes,the tb will report error just at the very beginning of run phase.

and sometimes the stimulation will complete .

the report info is like  : 

***sn_prof: sample #0 failed due to running out of memory.

     try profiling with -area_size = N, where N is greater than 16777216

 

and i just acted on what the suggest says,

extend sys

{ 

    setup() is also

    {

        specman("set profile -area_size = 25000000");

    };

};

i don't know why???

redrabbit thank you in advance!

  • Try increasing the absolute_max_size setting, as this limits how much
    memory Specman can request from the OS in total.
    Also, your settings code would be cleaner if you swapped specman("set
    ...") to set_config(). Minor point ;-)

    extend sys {
    setup() is also {
    set_config(memory, absolute_max_size, 3G);
    set_config(memory, max_size, 2500M);
    set_config(profile, area_size, 300M);
    };
    };
