The spiral model is similar to the incremental model, with more emphasis placed on risk analysis. The spiral model has four phases: Planning, Risk Analysis, Engineering and Evaluation. A software project repeatedly passes through these phases in iterations (called Spirals in this model). The baseline spiral, starting in the planning …

The first stage in the EDLC (Embedded Development Life Cycle) is requirements gathering. Once the requirements gathering is done, the objectives of designing the system are to be identified. Then we need to design the architecture or the block diagram of the embedded system. Then the detailed design of each …
