From test method to product

Six test methods across the product portfolio

Choose an observation, simulation or analysis method for your test. Select a product with the physical interfaces and released functions for your DUT (device under test) and configuration.

Configure
Make test intent explicit

Define the DUT role, interfaces, parameters, automation and evidence you need before choosing the hardware.

Explore comframe
Simulate
Control counterpart behaviour

Test nominal, boundary and non-conform behaviour within the released product and protocol scope.

Professional Simulation
Measure
Keep physical and protocol layers together

Review communication, low-level signals, power and application states on a shared time base.

Explore EVCA
Analyse
Connect observation and expectation

Compare measured behaviour with the applicable technical rules using the released evaluation functions.

Automated Standards Analysis
Validate
Repeat an approved test method

Use versioned test logic and controlled configurations with a defined scope for each verdict.

Conformance Test Libraries
Preserve evidence
Keep result and configuration attributable

Keep test identifiers, measurements, decisions and reports together for development, release or production.

Charge Cycle Automation
