question about GC on-the-fly

redrabbit

hi guys,

i wrote such a lot segments of code with e,but specman always do GC in the period of gen, i really have no idea about the location  of my improper codes,i look up for the specman performance profiler ,but still can not know exactly where the bad code is.guys,plz help me out of that ,thanks in advance.

  • Specman isn't commenting on the quality of your code when it's doing garbage collection! ;-)

    It has a threshold setting, so that it waits until a certain amount of allocated-but-free memory is present before it does a clean up.
    You might try increasing the GC threshold via the GUI or set_config(), so that GC happens less frequently.

    If you generate a lot of structs, then try using the gen debugger to see what's being generated. If you're using IntelliGen, then the debugger is really quite good for understanding the effect of your constraints.
