Dr. Ambar Gadkari, Principal Architect at KPIT, spoke at the Automotive Testing Expo 2015 North America on 'Rigorous Analysis & Comprehensive Verification of Embedded Automotive Software'. He shared with the marketing team, his views on the development that will impact Verification & Validation (V&V) in the Automotive Industry.

Excerpts

Today software is playing a critical role, more than ever before, in the automotive industry. Software issues have led to expensive recalls and OEMs & Tier1s are troubled by these issues being found in stages of production, sales and aftersales. This is pushing them to continuously evolve rigorous and effective V&V process that helps detect new and existing defects early in the SDLC.

Some of the typical challenges OEMs & Tier-1s are facing and trends in V&V in Embedded Automotive Software space are:

The Ever-Increasing System Complexity:

As system complexity increases, organizations are forced to cope-up with these intricacies by introducing and evolving newer validation methodologies. There are multiple systems and subsystems in a vehicle that interact with each other. For example, today the infotainment system interacts with active safety or ADAS systems which in turn talks to the braking system. All this is controlled by the electronics software. This increases the need for development standards in building safety-critical systems that need to be validated thoroughly in software as well as in control systems. Hence, the V&V process has to evolve to capture these changes.

The need for including and validating safety-critical system development standards in software and control systems has increased.

The New Trends in Development Workflow

Newer best practices are being adopted in software development like reducing testing redundancy, bringing more optimized workflows and re-using test vectors or test scenarios that can be done at various stages. These demand a robust V&V process.

Trend Towards Common Tools

In traditional V-cycle model, left side is for development and right side for validation. This is changing. Now V&V is shifting more towards the left side of the V-cycle. This is driven by the philosophy 'Earlier you catch, it's less costly to fix'. Ample efforts are being made to ensure the requirements, models and the artefacts that are used in development, go through the V&V stage. So far, the development tools and validations tools were separate but they are now being brought together.

Some of the key questions being asked are

Compliance with industry standards ISO26262, CMMI and AUTOSPICE require V&V as a practice to improve final software quality.

KPIT has been at the forefront in providing high quality V&V services to its clients and thus, leading the industry by example. At KPIT developing V&V solutions include process steps, combination of methodology & tools that are referred to as workflows. KPIT offers its clients a combination of methodologies and tools that constitute the workflow. This solution is a combination of process steps and tools. In some cases, we have also developed our own in-house automation tools. KPIT, with more than 12 years of extensive and rich experience, has deep insights in areas that need automation or optimization.

This is where the company has invested in creating its own tools, so that the process gets more automated during implementation. Since we have some of these tools readily available, it becomes much easier and a lot faster to build solutions as per the customer needs.
