Integrate DUT Control With Receiver Testing

Automate physical layer device control by coordinating management-interface access with the receiver test sequence. Engineers need reliable read and write operations for configuration, operating-mode control, error-counter retrieval, reset operations, and diagnostic status. The automation flow begins by establishing the required device state, starts the receiver measurement, retrieves the relevant status information, and resets the device before the next test cycle. Because vendors can expose different register definitions and communication methods, the control layer must preserve device-specific access while presenting a consistent test interface.

A practical integration method is to place vendor-specific device access behind a command-line interface or standardized adapter layer. The automation software can then issue common test commands while the adapter translates those commands into the required PHY communication sequence. Synchronization between the test system and device firmware is maintained so configuration, stimulus, measurement, and error retrieval occur in the expected order. This approach supports repeatable receiver compliance automation, reduces test-sequence differences between devices, and makes it easier to capture register results alongside BER measurements and other test records.

Automated PHY Control Solution

Build the automation workflow around reliable device configuration, measurement control, error retrieval, and reset operations before sequencing a full receiver test. The receiver test solution can coordinate instrument control with device status collection while preserving vendor-specific PHY communication through an adapter or command interface. Engineers can standardize commands for configuration, error-counter access, reset, and diagnostic monitoring without requiring the overall test sequence to change for every device implementation. This structure supports repeatable Automotive Ethernet compliance testing and allows measurement results, device status, and configuration data to be stored together for analysis and reporting.
