I have 2 questions.
1. How to attach techlib to file.
It requires me if I need to create project with topology. How can i attach concrete texhlib if I know path of it.
2. How attach .scs model file (for example, model of diode, transisor) to project?
Please read the Forum Guidelines.
Search in the documentation for "Technology File Manager" - in IC61 the Help menu works too to get you to the right place. If that doesn't help you, look in <ICinstDir>/tools/techuser/techuser.pdf and read the details there.
Or you could post a specific question and say what your actual problem is (don't append to this thread as it is over 3 years old).
