Embitel’s Model Based Development Methodology

The Model Based Development V-Model Showing Every Stage of Development & Testing

Knowledge Bytes
  Why choose Model Based Development Over Manual Coding
  • Reduced system complexity
  • Test suite reusability
  • Design reusability to multiple hardware target deployment
  • Automatic code generation
  • Continuous error identification and correction
  • Enhanced efficiency of up to 50%
  • Reduced time-to-market and overall cost of development
  What is Model Based Development?
    • Model based development (MBD) is a software development methodology based on V-cycle.
    • The model based approach enables a developer to simulate the models for the complex control processes.

These software models can be tested to assess the performance in real-time. Once finalized, the code can be auto-generated from the models, using code generation tools.
This way, the product can be tested at every stage of its development before the code is generated.

Here is a snapshot of Model Based development process:

  • Requirement Maturation: Hardware and Software requirement analysis is performed as the first step to weed out maximum number of design issues.
  • Model Simulation: The desired functionalities are expressed in the form of mathematical formula which eventually become models using simulation tools like MathWorks Simulink.
  • Testing and Validation: Software-in-loop, model-in-loop and hardware-in-loop testing are performed on the model. As it is an iterative cycle, any issue found at any stage is rectified by tracing it back to its previous stage.
  • Code Generation: Code is auto generated from the tested and verified models.
  What are the Advantages of Model Based Design and Development?
      The advantages are many that have made model-driven approach, a method of choice for automotive software development. Model Based Design approach renders a great value-add for development of powertrain and chassis control applications, in particular.

A few of MBD’s advantages:

    1. Continuous testing of the software at every stage ensures that it is free from bugs/ errors and is of the highest quality.
    2. Time-to-market is reduced considerably as code doesn’t have to be written manually.
    3. MBD makes it easier to design Complex functions, as it requires less iterations.
    4. Cost of development is reduced.
    5. Test suites can be reused for different production programs.

      A. Our Model Based Software Development team follow the industry accepted V-cycle SDLC Model. Over the last 12+ years, we have achieved ensured complete compliance and alignment of this V-model with enterprise level QA modules such as

CMMI Level-3




The quality of the artifacts and documents generated throughout the development process are in compliant with CMMI Level-3 and/or ASPICE.

We have also worked on projects where we delivered the artifacts compliant to both CMMI Level 3 and ASPICE, as per the requirements of the customer.

      A. For one of our Model Based Development projects, we developed an

automation tool

      that could convert libraries of

floating point to fixed point model

    . This conversion was the step prior to generating the code and integrating it with the low-level drivers.

Completion of this conversion manually would have taken more than a week for a developer. Also, it would be error prone, as a lot of data type changes and I/O port name changes would have been required.

However, with the help our Automation Tool, we could convert 16 such libraries to fixed point in 1-2 days.

The benefits for the customer were

  • More accurate conversion, better quality of the code and very less turn-around time.
      A. Yes, post-integration support is part of the

Service Level Agreement

      (SLA). Any kind of bug fixes and change requests, during or post the integration in production environment are part of our model based design support and maintenance services.

If required, our Model Based Design experts can also travel to the customers’ location for an Onsite Support.

      A. Yes, Embitel has all the necessary skill-sets to help you setup Model Based Software Development process.


    Our MBD experts will help you with the following processes:
  • Support for Documentation related to each and every phase of V based SDLC model.

  • I/O documentation for every phase of V-cycle as an evidence for CMMI or other QA audits
      A. We have expertise in designing both Non-AUTOSAR as well as AUTOSAR based MBD models.


      Our MBD experts have worked on projects where standard


    guidelines have been followed for model creation, data type nomenclature, I/O names, vehicle diagnostics and more.
      A. When you partner with Embitel for Model Based projects, you can expect to collaborate with an expert core team of Model Based Development Consultants, Project Managers and Automotive Engineers.


    Here is the team hierarchy that is most commonly followed in the Model based software development project.

  2. Senior MBD Consultants with 14+years of experience, to partner with you for critical automotive projects for product (ECU)/application development and consulting support.
  3. Senior MATLAB programming experts proficient in developing automotive ECUs/applications as per the latest industry standards including MAAB, AUTOSAR, and ISO 26262.
      A. We can help you with a phased adoption of Model Based Development paradigm after in-depth review of the architecture of your existing product line.

Here is a brief overview of how a MBD adoption/migration approach may turn out be:

    1. Getting ready for the migration: Includes assessment of current state of the development process and learning the core MBD tools.
    2. Feature selection as per project scope: Understanding and fin-tuning of scope and requirements at every phase of development, selection of features, modeling and simulation and code generation.
    3. Component selection and physical modelling: Activities include Expand modelling, simulation at component level and introduction of plant modelling.
    4. Standardization: Performing Simulation at system level and full model based verification and validation. Best practices like introduction of tool automation and creation of reusable libraries also come into picture.
    5. Optimization: The final phase is to align the MBD approach with enterprise vision and goals. Objective is to make the processes fully automated and optimized.
