I can get an eye diagram with the option ".options baudrate=rate". but the menu Plot Settings->Eye Diagram->Enable and Plot Settings-Eye Diagram->Properties are grayed out. I guess you can switch the normal view and eye diagram and also shift the eye location with through menu. Is there someboday who knows how you can bring up those menus?
Can you please specify which tool you are referring to, so the correct people can look at your question?
Thanks for your suggestion. I am using the newest version of LTSPICE XVII.
