Hi,

I am not sure whether there is M.Tech in design. You see CEED is the design exam and most engineers write it to go for M.Design at 

IISc Bangalore: Center for Product Design and Manufacturing

IIT Bombay: Industrial Design Center

IIT Delhi: Instrument Design and Development Centre

IIT Guwahati: Department of Design

IIT Hyderabad: Department of Design

IIITDM Jabalpur: Design Discipline

IIT Kanpur: Design Programme

Check the details in this article. For CEED, you need to develop a protfolio of your own and you definitely dont need to learn any design software. 

Pls check the course you wish to join because as far as I know there is no M.Tech in design.
