Encounter library charaterizer could not read the hspice IBM model file

Satendra

 Hi Everyone,

I am new on ELC. I ran the tool for characterizing my design but it could not even read the model files. Can anyone please help me on this.

I read several posting on this blog and tried everything but could fix it.

My elccfg looks like this

EC_SIM_USE_LSF=1;
EC_SIM_LSF_CMD="";
EC_SIM_LSF_PARALLEL=3;
EC_SIM_TYPE="hspice" ;
EC_SIM_NAME="hspice" ;
#EC_SPICE_SIMPLIFY =1;
EC_SPICE_SUPPLY1_NAMES="vdd! VDD!";
EC_SPICE_SUPPLY0_NAMES="vss! VSS!";

SUBCKT="./netlists/static_shifter_cell.pex.netlist";
MODEL="../hspice_test/models/design.inc";

SETUP="demosetup.cfg";
PROCESS="process_corner";


 I tried replacing Model with LIB but did not work. I even created model_type file with these commands in it

* This first line should be a comment line in the MODEL_FILE we are creating

simulator lang=spice

.lib "/hspice_test/models/design.inc" tt

 Still I could not get any success.

  • Dear Satendra,

    There could be many different reasons why your simulator fails reading in the model files in your ELC simulations. As the best way to find out the reason, I'd recommend you to run stand-alone simulation using a spice deck created within ELC.

    Please add -keep_work to your db_spice command in ELC command file. This will keep the Spice decks in the directory name, encounterlec.work by default. Go to one of directory, then run your simulator. This will save the spice log, where you'll see the error messages which may tell you, for example, which model files are missing, or if model syntax is not accepted, etc. 

    The "MODEL" keyword in your ELC config file needs the spice models, not the dotlibs.

    Please let me know if you still get problem.  You can reach me by the email, keeshik@cadence.com

  • Dear Cadence/ETS/ELC Team,

    I'm from UFRGS/Brazil, and I'm using ELC to characterize the a couple cells at the 65nm node. Using very simple MOSFET models, like PTM, ELC works just fine. However, when I introduce a model with higher complexity, in my case, the IBM 65nm, the ELC fails to recognize the model/lib used.

    It pretty much seems to me that ELC is not able to recognize this kind of expressions:

    mc_gl_f     = '(mc_global>0)*mc_sw'  

    I appreciate very much any help/support with this issue.

    Regards,

  •  hello ,

    thanks for reading

    when I use ELC，db_spice  -s spice -p typical -keep_log

    The result is

    ipsc[0] :not found

    [ERROR(db_spice)】 cannot  establish client-server

     can you help me handle the problem ,

    thanks,and my QQ number is 254530108,looking forword to your reply
