1.the files myopti .asc, myopti_init, myopti.net you should need to optimize my curve 
2.File 82543250_Meßwert has all of my measurement values . 
3.File Library is the subckt codes , you need it for ".inc Library.lib" , which you can choose one of 2 article 82543250 or 8531140 
( but only 82543250 worked , 82531140 not but it isn't wrong), please check myopti.asc , and use " Parameter of my 2nd simulation: 82531140" as spice diretive
 

What i need your help are 
1.Optimize the simulated curve by using PERL or some the programms you know ( the simulated curve should be near the form the measurement curve)
2. put 2 articles in a Library.lib and choose one of them

Note: if you would like to use Library.lib you should change the symbol xvaristor to xvaristor_W.
