The standard EN 50657:2017 specifies the process and technical requirements for the development of software for programmable electronic systems for use in rolling stock applications. The standard adapts EN 50128:2011 for the application in the Rolling Stock domain, but is shares a lot in common including the definition of the Software Integrity Levels (SIL).
For our static analysis tool QA-MISRA, our tool Qualification Support Kit (QSK) automatically executes a full tool qualification verification test suite on the installed tool configuration and generates the necessary reports for EN 50128 / 50657 tool qualification.
EN 50128 is a functional safety standard used in the rail industry. It provides requirements for developing, deploying, and maintaining railway software. This includes applications for communication, signaling, and processing systems.
This methodology handbook provides detailed explanations on how to fully satisfy requirements of EN 50128:2011 (Software for communication, signaling and processing systems) and EN 50657:2017 (Software for rolling stock applications) with a SCADE model-based development approach to achieve safe and reliable software, while promoting an efficient model-based development and verification strategy.
The handbook introduces the EN 50126, EN 50128, EN 50657, and EN 50129 standards before presenting the optimization of the software development and verification processes that can be achieved with the SCADE toolchain and methodology. SCADE tools support the automated production and verification of a large part of the development lifecycle elements. The effect of using the SCADE toolchain is presented in terms of savings in the development and verification activities, following a step-by-step approach and considering the objectives that must be met at each step.

Because IEC 61508 serves as the meta-standard for a range of industries and published standards, the Platform for Industrial Safety is directly applicable to railway (CENELEC EN 50128), medical (IEC 60601), nuclear (IEC 61513), process control (IEC 61511), and automotive (ISO 26262).
The MULTI toolchain has been certified to meet the highest levels of tool qualification specified in the IEC 61508:2010 (Industrial), EN 50128:2011 (Railway) and ISO 26262:2011 (Automotive) functional safety standards. MULTI is the only commercially available toolchain certified to satisfy both SIL 4 (Safety Integrity Level) and ASIL D (Automotive Safety Integrity Level) tool qualification requirements.
Static analysis is an important technology for developing software that needs to achieve high levels of functional safety. CodeSonar is pre-qualified for the highest levels of safety for the IEC 61508, ISO 26262 and CENELEC EN 50128 standards by Exida. Artifacts for qualification according to DO-178C / DO-330 are also available.
Transportation systems and, in particular, railway systems, are growing markets that increasingly rely on software for command, communication, and control. Due to the impact of errors and accidents in this environment, software is developed to strict standards such as EN 50128. The standard is very specific on the use of good programming practices, tools, and techniques.
Source-code compliance
The EN 50128 standard is very clear on using good programming techniques such as modularity, components, structure, and object-oriented programming. It also requires the use of design and coding standards, and language subsets such as MISRA C. In fact, these coding standards are mandatory for higher safety-integrity levels SIL 3 and 4. Static analysis tools such as GrammaTech CodeSonar are very good for enforcing coding standards, whether commonly-used standards such as MISRA C or customised versions specific to your application.
Satisfying EN50128 requirements
The following table illustrates how specific EN 50128 requirements are met with a static analysis tool such as CodeSonar. In many cases the techniques/practices are highly recommended, if not mandatory, at the most critical levels.
Supporting certification
An important part of satisfying the requirements for EN 50128 is not just compliance but documentation to support proof of compliance. Automated software tools, including static analysis, provide reporting that supports the certification effort, and with the additional benefits of risk mitigation and developer time savings, the use of automated tools means quicker time-to-market and development dollars saved.
Static analysis tools have an important role to play in safety-critical software development. The EN 50128 standard for railway software systems is clear in its requirements and highly recommends static analysis for any system SIL 1 or above. Supporting the certification process with certified tools reduces risk, costs, and time.
