problems in using ELC(encounter library characterize)

my elccfg file is :

SETUP = "setup.ss"
PROCESS = "typical"
SUBCKT = "dut.scs"
MODEL = "wwk.scs"

setup.ss file is :

// Encounter Library Characterizer setup file

// Define voltage and temp for process corners
Process typical{
 voltage = 5.0;
 temp = 25;
 Corner = "TT";
 Vtn = 0.67;
 Vtp = 0.92;
};

Process best{
 voltage = 5.5;
 temp = 0;
 Corner = "FF";
 Vtn = 0.63;
 Vtp = 0.89;
};

Process worst{
 voltage = 4.5;
 temp = 125;
 Corner = "SS";
 Vtn = 0.71;
 Vtp = 0.92;
};

// define measurement percentages for std_cell measurements
Signal std_cell {
 unit = REL;
 Vh=1.0 1.0;
 Vl=0.0 0.0;
 Vth=0.5 0.5;
 Vsh=0.8 0.8;

Can you help me ?

Thank you for you attention

 Hello,

Did you manage to solve this problem?

I have the same case ()

DESIGN INV should give

INPUT A ( A );

However it gives

 FEEDTHRU A ( A );

As a result the gate is not recognized by the db_gate

Thanks for your concern

 OK

I think that the problem is the model library.
I worked on a subset of the ami lib (trying a tutorial on elc) and I had problems.

However when I did the same tutorial with mine umc90 lib everything rolled smouthly and as should.

I even managed to have verilog and alf formats of the design

elc>  db_gate


==============================
      DESIGN : INV
==============================
DESIGN ( INV );
//      =================
//       PORT DEFINITION
//      =================
        INPUT A ( A );
        OUTPUT Y ( Y );
        SUPPLY0 GND ( GND );
        SUPPLY1 VDD ( VDD );
//      ===========
//       INSTANCES
//      ===========
        NOT ( Y, A );
END_OF_DESIGN;


elc>  db_close

I really hope that this helped.

Hi, I encountered the exact same problem, but got to fixed it after some struggling. I figure it is better to have it documented here.

Actually it is the model file, check if your model file is in the spice format. If so, convert it to the spectre format. In my case, ELC was running without problem after I convert the model file using

spp -convert <model.spice> model.spectre

Help it can help others someday.
