B.tech Student design electronics devices.
The design methodology at most levels is pretty much similar.
1. Decide what features your device needs - You decide on the performance, price and size restrictions. This is usually done in sync with a marketing team who go talk to customers and take feedback.
2. Make a plan for the design process - Once you have the budget decided, you then decide on what features you can put into the device and still have enough budget left for the design and verification efforts. You decide on that modules to put into the design and prepare a rough timeline for the whole process.
3. Deciding on the vendors - The next stage is to decide who the vendors will be for the various modules in your design. It could be the vendors for various chips in your TV, or the different controllers and components on your IC. You see if you want to use your in house design, or license the design from someone else for any specific module. At the same time you also decide on vendors for verification modules for your design. Again, it could be in house or external
4. Actual design and verification - Both the design and verification teams now start working in parallel on the design, putting everything together and checking it at the same time. You will have a couple of actual physical designs manufactured as prototypes to see if everything is working as expected. At the later stages, it all turns to patching and bug
