Description

The MediaLB Interface Test Bench (MITB) is a hardware test setup used for verification of both the physical layer of a MediaLB interface and the link layer implementation of a MediaLB device1. The test setup is based on the loop- back functionality of the MediaLB Device Under Test (DUT) and incorporates data checker software for test pattern generation and verification.

When performing a test, the MediaLB DUT must be connected via its MediaLB port to the test bench, which generates and transmits test patterns. These patterns are received on the MediaLB port of the DUT. To confirm correct data flow, the DUT performs a loop-back function, which allows the retransmission of the test patterns. The retransmitted patterns are received by the test bench and verified against the transmitted patterns.

The MediaLB Interface Test Bench provides a USB interface to the host PC. By means of the GUI, various test cases can be defined to verify different MediaLB port configurations according to the MediaLB interface mode, clock speed, channel allocation and transferred data type. Also, test results are displayed on the GUI.
