Tool/software: WEBENCH® Design Tools

Hi Experts,

1. I want to do an AC analysis for my Buck converter. For which I need an Average model of LM5116. It is available in Psipce. I am using the Tina12 Industrial version. How Can I import it into Tina12?

Currently, I tried it with the Transient model. I am getting the below error (Screenshot attached.). What is this error. And How to resolve it? I tried changing the analysis parameter too. Attaching the Simulation file as well.

2. The link is a good tutorial for learning. Although it doesn't show how to change parameters such as crossover frequency or doing measurements in webench. Can you tell me more about it?

    Hi Imran,

    Thanks for your response. The Steps Shown are only applicable for.TSM Format. When I go to Insert->Macro, It is asking me to select a.TSM file. How to Import .lib files?
