spectremdl montecarlo simulations, how to fix my errors ?

samung
Hello,

I would like to launch some montecarlo simulations through spectremdl commandline interface.

I launch :
spectremdl -batch input.mdl -design input.scs -measure mc_results_file/results_file +log mc_log_file.log

I have the errors :
Error found by spectre.
    ERROR: line 11, column 2: syntax error before or at: <eof>
            unrecognised statement
    ERROR (MDL-6): Failed to parse MDL control file, `input.mdl'.

I don't know how I can fix these errors. Could you please help me ?

Thanks !!

Pedro


I have the following files :

  • Regarding the spectre method, I have the feeling I need the amap/ directory otherwise I have the error :

     *Error* _ymaxMethod: can't handle _ymaxMethod(nil)

    Error found by spectre during Monte Carlo analysis `mc1'.

        ERROR (SPECTRE-8003): subckts: Error evaluating ocean expression

            `aout_b_max=ymax(v("/aout_b" ?result "tran"))'.

    Unsuccessfully evaluated export statements (based on return code).

    Analysis `mc1' was terminated prematurely due to an error. 

     

     

    I found that doing the simulation in the adexl simulation database (.../xxxdesign_cell_namexxx/adexl/results/data/MonteCarlo.0/2/Test:xxxdesign_cell_namexxx:1/netlist/), whereas until now I was just simulating in a remote location.

     

    ...> ls amap/

    __multiplefiles_amap_format__          __simulator_information__              cmosxxx_psvtlp_SimMosfetStandard.inst  xxxdesign_cell_namexxx.inst      ncx.inst                               top_level_map.net

    __new_amap_format__                    analogLib_res_hspiceD.inst             inv.inst                               xxxdesign_cell_namexxx.net       ncx.net                                top_level_map.port

    __nmp_amap_format__                    cmosxxx_nsvtlp_SimMosfetStandard.inst  inv.net                                xxxdesign_cell_namexxx.port      top_level_map.inst 

     

    How it comes I cannot simulate without an error my input.scs with the export line : export aout_b_max=oceanEval("ymax(v(\"/aout_b\" ?result \"tran\"))") if I don't have the amap/ directory ? 

    To my point, I should be able to launch the commandline : spectre input.scs +log mc_log_file.log with only :

    _graphical_stimuli.scs

    corners_SS.scs

    global_flags.scs

    input.scs

    netlist

    stat_flags.scs 

     

    Thanks.
