I have constructed my circuit using your models. But when I run the project, it gives some errors saying few parameters had to be ignored. I have divided my project into 2 parts, the first part which contains AD8331(LNA) works perfectly. But while running the whole project, simulation fails somehow. In the second part I have included LVDS and AD8333. When I tried to run only this document, it runs only for 1.6ns! Simulating only LVDS also works fine. https://easyeda.com/editor#id=kqPN9ljhe|wHBTN5nFX This is the link. Could you please have a look and guide me on why it runs only for such a small period or why it ignores certain parameters? Thanking you.
