A good quality thesis can be generated on a short deadline if the right approach is used. Firstly, it is very important to get yourself in the correct frame of mind and stop taking too much stress of your PhD thesis. Once you know how to deal with your panic and stress situation you will definitely do well in your course work. Check your submission date before beginning and start acting decisively due to the limited time you will have to make tough decisions very soon. You will have to decide that you will not do certain things and will have to focus on your work with energy and determination.
As the thesis and research will be time taking you can side project that is based on someone else work which can be beneficial for producing results instantly and will secure your time. This side project can help you in amazing ways to generate interesting results in your career. The next important thing you need to do is to finish your research before you start writing your thesis because again and again going back to the research side will only waste your time and energy so do your research thoroughly at first and then after enough of research you can start writing. However, it is very easy to write when you have done enough of the research. 
You can choose to work at a place where you find less distractions such as your library, you have to get rid of many extra activities like minimize your internet connections and lessen your curricular activities for this period. Fix a comfortable area for you to work just for your thesis writing. Set your targets that you will do in a day at any cost and be consistent on it in order to meet the deadline. By being consistent you yourself will feel good about your progress and you will feel confident that your work is in progress and will be finished on time.
The most important is to set your routine that starts with your beginning and the end of the day. You should know what you will do the next day and be motivated for that as well, better make a check list. You can apply the ruthless standards to the things you include whether it is a literature that is excellently written to save your time, just focus on those points that makes your thesis shortened,faster and simpler as well as easier to write with a high-quality content. Make sure that you constantly reread your content and revise what you have written that will result into less revisions when you submit your thesis to your supervisor. This will save your months and make you more-closer to the right at the few first rounds only.
Another best way to keep your work stress free and get it done within the available time period is searching for the best possible samples so you cannot just find the relevant literature but also a template to add on your work.
