Case Study: ALTEN achieves EN 50128 SIL4 software validation with Vector Software's VectorCAST

Meeting the Challenges of EN 50128 SIL4 Software Validation

ALTEN Italia, a Milan‑based engineering and technology consultancy serving industrial, telecommunications and services clients, needed a proven way to validate railway software and meet the functional testing and code‑coverage objectives required by CENELEC EN 50128:2011 (SIL4).

They implemented VectorCAST, an automated platform for functional testing and structural/code coverage analysis. The VectorCAST tools enabled ALTEN engineers to perform the required testing and coverage measurements and helped them achieve compliance with EN 50128:2011.
