Keep Your Railway Embedded Software on Track with CENELEC Standards

Wer die strengen Standards der Bahnindustrie einhalten will, muss sich auf planbare und reproduzierbare Softwareabläufe verlassen können. Die Anforderungen der Bahnindustrie werden vom CENELEC definiert, dem Europäischen Komitee für Elektrotechnische Normung. Die drei CENELEC-Normen EN 50126, EN 50128 und EN 50129 sind die Grundlagen für die Nachweisprozesse hinsichtlich der Sicherheit eines Eisenbahnsystems.

Die Normen EN 50128 "Software für Eisenbahnsteuerungs- und Überwachungssysteme" und EN 50129 "Sicherheitsrelevante elektronische Systeme der Signaltechnik" sind die bahnanwendungsspezifische Interpretation der internationalen Normenreihe IEC 61508 (funktionale Sicherheit elektrischer / elektronischer / programmierbarer elektronischer Sicherheitssysteme).

Die Norm EN 50128 enthält Software-Sicherheitsanforderungsstufen (SSAS/SIL) sowie Vorgaben zur Qualifikation des Personals und zu deren Verantwortungsbereichen, zum Lebenszyklus und zur Dokumentation. Sie enthält eindeutige Beschreibungen von Zielen, Eingabe- und Ausgabe-Dokumenten und Anforderungen an Software-Anforderungsspezifikationen, -Architektur, -Entwurf, -Imple-mentierung, -Verifikation und -Tests ebenso wie an Software-Hardware-Integration, Software-Validierung, Qualitätsmanagement und Wartung.

Die Norm EN 50128 gibt fünf Software-Sicherheitsanforderungs-stufen vor: SSAS 4 entspricht sehr hohen Sicherheitsanforderungen; SSAS 0 bedeutet keine Sicherheitsanforderungen, wie zum Beispiel bei Management-Informationssystemen.

In anderen, auf IEC 61508 basierenden Normen, gibt es zwei unterschiedliche Definitionen von Sicherheitsanforderungsstufen. Die Demand-Mode Definition laut IEC 61508 gilt für Systeme mit intermittierendem Betrieb (wie zum Beispiel solche, die unter die Norm EN 50128 fallen), während der Continuous-Mode für Systeme mit einer hohen Anforderungsrate zur Anwendung kommt. Aus der folgenden Tabelle gehen die Unterschiede zwischen den beiden Definitionen hervor sowie die Auswirkung eines Systemversagens auf den einzelnen SIL-Stufen.

Vollständige Prüfung eingebetteter Software sicherstellen

Unternehmen, die Wert auf einen berechenbaren Softwareablauf legen, müssen sicher sein können, dass der Anwendungscode zu 100 % getestet wurde. VectorCAST/Covererfasst deshalb während der Systemtestaktivitäten Abdeckungsinformationen, mit deren Hilfe sich die Systemtestabdeckung feststellen lässt. Bei Bedarf können dann für bestimmte Anwendungsbereiche weitere Tests durchgeführt werden.

Warum Systemtests allein keine 100%ige Zuverlässigkeit garantieren

Systemtests führen nicht automatisch zu einer 100%igen Abdeckung, da viele Funktionen Fehlerbehandlungscode enthalten, der mittels der vollintegrierten Anwendung nur schwer oder gar nicht stimuliert werden kann. Die Lösung besteht in der Durchführung von Modul- und Integrationstests mittels VectorCAST/C++ oder VectorCAST/Ada. VectorCAST/Cover nutzt Abdeckungsinformationen gemeinsam mit VectorCAST for C/C++ und VectorCAST for Ada, sodass Sie problemlos Berichte erstellen können, in denen die Abdeckungen sämtlicher Tests erfasst sind.
