Level 1 · Entry Foundations

Goal: understand what makes automotive ECU testing different from general software testing, get fluent in CAN bus fundamentals and frame structure, understand what Vector CANoe is for and how CAPL scripts drive it, learn the shape of UDS diagnostics and Hardware-in-the-Loop (HIL) testing, apply solid test-case design to ECU signals, and know where the industry's standards (ASPICE, ISO 26262) touch testing — then put it together by designing a CAPL test script for a simulated ECU signal.

About this track

Vector CANoe, CAPL, and real HIL test benches are specialized commercial tooling and physical hardware — they cannot be installed or exercised on a general-purpose machine the way a compiler or interpreter can. Every lesson here is written and checked for technical accuracy against genuinely documented CAN, CAPL, and UDS (ISO 14229) conventions and real Vector tooling behavior, rather than against live execution. Where an example shows CAPL code or a CANoe workflow, treat it as a faithful worked example to study and adapt — not a transcript of a script that was actually run.

By the end of this level you'll be able to explain how automotive testing maps onto the V-model, read and reason about CAN frames and arbitration, describe what CANoe does and why teams use it, write basic CAPL event handlers that send and receive CAN messages, describe UDS request/response diagnostics, explain what HIL testing is and why it exists, design test cases for ECU signals using equivalence partitioning and boundary analysis, and connect ASPICE/ISO 26262 to concrete testing obligations.
