ERTMSFormalSpecs (EFS) is a workbench used to model and animate ERTMS specifications for onboard units.
The whole modeling process, from requirement analysis to testing, is made easy thanks to its functionalities and graphical interface. Furthermore, EFS sets a huge emphasis on traceability to easily navigate from the requirements to the model and backwards. Thanks to the traceability, we can compute metrics and identify gaps in the model and tests.
It includes 100% of Subset-026 ERTMS Business Logic, allowing you to:
- Test your EVC
- Validate Subset-026 change requests
- Perform early-stage development and validation of operational test cases
This workbench satisfies two contradictory objectives: being understandable by the signaling expert and being formal enough to be animated.
It includes a DMI window showing the model state and a Scenario Editor which helps defining and playing the scenarios.
With its 100% model coverage for onboard requirements specified in Subset-026 and 027, we claim that the tool is efficient to model and simulate real EVC-related situations.
