Eg.:

  cell (AND2_X1) {

 

     drive_strength     : 1;

 

     area               : 1.064000;

     pg_pin(VDD) {

          voltage_name : VDD;

          pg_type      : primary_power;

     }

     pg_pin(VSS) {

          voltage_name : VSS;

          pg_type      : primary_ground;

     }

 

 

     cell_leakage_power : 15.154826;

 

     leakage_power () { ………………………
