EVC Test

EVC Tests (SUBSET-076 & SUBSET-094)

Accredited 17025 Tests since 2011

The aim of this service is to provide EVC (“European Vital Computer”, the European ATP “Automatic Train Protection” or OBU “Onboard Unit”) functional tests defined in Subset-076. Equipped by the most state-of-art technology and automate tools (hardware and software) developed in-house, the EVC accredited laboratory of Multitel is capable of providing the most detailed test report in the fastest time according to the full UNISIG SUBSET-026, 076 and 094. The report provides the reasons of the failure and points out the observed values side-by-side with the expected values and shows links of the observations up to the requirement level.  In  case  of multiplayer protocols like Euroradio protocol, our reports can show the  communication  layer  by  layer,  with  the  protocol  detailed  in  a human readable format. Besides functional tests, we offer also performance and reliability tests of components or equipments to railway industry for production quality control or pre-certification.

Test Campaign Duration: in our laboratory, we have delivered for both baseline 2 and baseline 3 test campaigns within 2 weeks per campaign. This includes for each test campaign: running all test sequences, validating and revalidating all test sequences and the final report according to ISO 17025.

Related Emulators: Multitel provides emulators for RBC (MRL-BCD-EMU), TSR (MRL-TSR-EMU), KMC (MRL-KMC-SS114 following Subset-114 and MRL-KMC-SS137 following Subset-137) and EVC emulators (VCD – Vital Computer Debugger: MRL-VCD-EMU).

Related Tools: MRL-SA-TAV-EVC is developed in order to perform the validation of the results of the MRL-EVC-TB. The tool takes profit from the observable database provided with the Subset-EVC-DB to guide experts in validation.

EVC Design Tools and Databases: MRL-SCT-LED, MRL-SCT-TCD and MRL-SCT-TSD are the tools created by Multitel to design, update and create test databases. The MRL-SCT-LED (Language Editor) tool is used to create the language models. The MRL-SCT-TCD (Test Case Designer) is used to create test cases. And the MRL-SCT-TSD (Test Sequence Designer) is used to create the test sequences. Thanks to the use of these tools that the Subset-EVC-DB was created. Not only limited in the creation of databases for ERTMS standards (defined in the ETCS component), they are also used for KRTMS (defined in the KRTCS-2 component) and CTCS. These databases are also available in Multitel: Subset-EVC-DB-ERTMS, Subset-EVC-DB-KRTMS and Subset-EVC-DB-CTCS for different standard versions – including the database used in Subset-076 for EVC, but extended and enhanced with traceability to requirements.
