More and more electronic systems are used in safety-critical areas where errors can have disastrous consequences. Therefore, a careful development is a must.
Developing safety-critical systems according to special demands set down in the so-called safety standards is mandatory. These safety standards call for a lot of tests. TPT covers most of the obligatory requirements of the safety standards. TPT can be qualified for testing and verifying with regard to standards that regulate functional safety like ISO 26262 or IEC/EN 61508.
Concerning the automotive sector, the safety standard ISO 26262 demands a phase model for the development. This model has to respect safety-critical and functional aspects. The standard also explicitly formulates requirements for the test phase.
TPT is a tool that supports testing and verification of safety-critical software. According to the demands of ISO 26262, TPT can be used for software unit tests, software integration tests, verification of software safety requirements, and for integration testing, thus TPT can be used in all test phases. Tests can be executed in test environments like MATLAB/Simulink, ASCET, C-code, but also on PIL, HIL, and even in vehicles.
TPT can handle required test methods like requirements-based testing, interface testing, fault injection, boundary value testing, back-to-back testing, testing equivalence classes, and coverage analysis.
To use TPT for the development of safety-critical systems, you generally need to qualify the testing tool to show that it is reliable for the system to be tested.
The requirements of the tool qualification when developing safety-critical automotive systems are specified by the ISO 26262. The verification of the necessary “confidence in use” requires two steps: first, the tool needs to be analyzed and classified; second, the required qualification methods are derived and applied.
PikeTec offers a Qualification Package which efficiently supports the tool qualification and reduces time and effort significantly. The Qualification Package is certified for qualification of systems with a Software Integrity Level from ASIL A to ASIL D.
Our Qualification Package
We assists you from the first analysis up to the final qualification, from the first conversation up to the completion of all necessary documents.
We qualify TPT according to the method called “validation”. The validation is done manually and by using an extensive valdiation-suite.
