  • Offers advanced data-point and bus monitoring & capture to reduce verification efforts
  • Provides comprehensive on-demand diagnostic service execution
  • Validates diagnostic services and test sequences on real ECUs or simulated environments

ECU Validator

The ECU Validator is a tool that automates diagnostic compliance testing, including protocol testing and validation of ECU implementation. By incorporating the ECU Validator into your diagnostic data process, ECU conformity certification becomes an essential and manageable aspect, eliminating the need for it to be an expensive or optional feature.

Salient Features

  • Data-driven testing that leverages diagnostic data (ODX, OTX) to validate compliance to specifications
  • Support for bench-based setup with commodity interface devices, extensible to incorporate HIL fault-injection based testing
  • Automated execution of positive and negative test cases
  • Execution statistics and detailed test results
  • Test report generation, including executed test steps, bus & symbolic traces
