The first one, of course, is the achievement of your thesis, that is to say, if the topic is computer-related, it means that your topic will gain something after using the software, so it depends on the process and result of your software simulation or programming. This is acceptable, and it is usually accepted by other teachers. Before that, your mentor will accept it first;

The second is your thesis, which is a detailed work, including the explanation of the topic, the whole process of answering, the application of knowledge and theory, etc.

In the final thesis defense, there will be a defense group, which is usually a great tutor of related majors. Explain your topic first, then ask some questions and so on.

Basically only the above three points. As for the use of software, you can ask your tutor or classmates. Most people will use it, because they are all software tools similar to their majors.
