I am getting error during annotation of DC Voltage and current using AWR MWO. I am not able to find out how to get rid of this error. Actually I wanted to check biasing condition for Power Amplifier.

I have followed exactly same steps given in the MWO Getting Started guide. But I am getting error for my circuit and am not able to find what is the error?

I believe that is a compatibility problem. Or it's a particular isue.

Even I am not able to plot IV Curve plot that is also showing error. I have attached AWR MWO IV Curve plot file.
I have also attached IV Curve plot and error message. I am struck, someone can suggest me to move ahead.

Maybe this is some "divide by zero" error in the model, because it happens at I=0 and f=0. Have you tried to start from a non-zero current?

You have to refer Cadence Technical Support to overcome this problem.
It's evidently a compatibility problem so the model itself is either not compatible with version which you've been using OR the model has bugs.

Hi Narayani! The problem are solved in these ways.

Shorting all the pins of the MOSFET at the bottom, I don't think it's a solution..

From the developer's design, it is unclear how many transistors of the BLF647P assembly should be used in the circuit. If it is one, then the lower transistor should be excluded from the DC calculation by shorting all its terminals. Otherwise, the upper and lower transistors will short-circuit L2 and DCVS ID_V2 V= 32V. If the transistors are intended to operate in parallel, then the circuit needs to be configured in the second way.

I have attached AWR MWO DC Analysis 18 version .emp file. Generate DC annotation for this file

Hi Narayani! This is what I got after simulation

May I know which version of AWR MWO are you using?I am using latest 18 version and didn't get DC annotation. I have 18 version AWR MWO under university license program.
