Optimizer and equation issues in AWR microwave office

Hello, i have a problem with my design in AWR. I am simulating a HEMT transistor, made by the institute i am working for, and I have extracted some S-parameters and some I-V data. I made the schematic, imported the data files needed, but when I wrote some equations to calculate the error function (I thought of some kind of error equation ), i get an error that the sweep dimensions sizes are incompatible.This is the main problem that is affecting setting up an optimization setup. I posted the project with this thread....can someone help me with the equations please.

Hello,

This error means that the project simulation voltage sweep setps should be same for hemta_3 id vds IV data file & the IVsim Ciruit model Schematic ...

In order to make this just set the proper values for Drain Bias Sweep step say from -1 to 5V in steps of 0.1V then it works fine without error even the optimizer...

See the attached Modified AWR MWO file for your reference...

I hope this helps you...
