How to eliminate optimization error in ADS2022

[hari_preetha]

I am using ADS2022 for optimization of Power Amplifier. When I try to do optimization, I could not get proper optimization results. I am getting errors that file is attached below. It seems to be fine. I am not understanding why I am getting this error. Guide me some one how to eliminate this error?

You forgot to enter simulation name in OptGoal2 and OptGoal3

I have modified OptGoal2 and OptGoal3. Now I am getting different error. I have attached below error message files. Please have a look on it.

You didn't define optimization ranges. Can you upload the project file with process DK as .7ads format ?

As you asked in the previous posting, I have attached project file with process DK. I request you to address this issue.

As you asked in the previous posting, I have attached project file with process DK. I request you to address this issue.

Not in this way, save your project as archived format and include PDK in it. ADS will create *.7zads file. Zip it and post here.

Dear BigBoss,
As you asked in the previous post to save project as archieve format and include PDK, I have saved as you mentioned and attached it. Please have a look into it and give suggestions to eliminate the error.

You did some mistakes
-You entered 2 limits that contradict each other in "Goal" blocks. While you're defining a limit less than <> dB in 25-32, you also defined another limit Greater Than <> in the same frequency band. They were in a contradiction.
-You entered "freq" variable without units. You should enter them as 25e9 and 32e9.
Because ADS Optimization Engine does not know which unit you're working on.
I have corrected and re-named the project.You can continue to work but there are some other design problems because dB(S(2,1)) is negative, you have to correct this.

Can you suggest me anyone how to make S21 positive values because I have tried lot to make S21 positive values. I couldn't get it.

At first attempt, it seems working not bad.
