Designers of hardware systems relying on audio video bridging (AVB) have a new option to speed up the development of their products. Mirabilis Design's Ethernet AVB library is applicable to systems operating on AVB-based Ethernet and networks, and supports standards including the IEEE 802.1AS, IEEE 802.1Qat, IEEE 802.1Qav and IEEE 802.1BA.

The AVB library can be used in the design of automotive application, network ICs, professional video equipment, and networks for concert halls and studios.

This Ethernet AVB library is fully integrated with the VisualSim automotive network library and the VisualSim hardware architecture library to model, simulation and design complete systems. In addition to the Ethernet and AVB network, the system can contain other networks such as CAN and FlexRay, sensors, ECU, hardware accelerators, display units, video processors, and audio equipment.

Engineers can use the library components to create traffic stimulus to emulate sensors, and network traffic patterns. Pre-built parameters values can be modified by the users to experiment with different traffic inputs, traffic shaping algorithms, reservation quantities and hardware attributes to evaluate the impact on latency and throughput.

The Ethernet AVB library consists of AVB traffic generators, talkers, listeners, stream reservation protocol, registration, traffic shaping and clock synchronisation. The pre-built statistics includes latency plots for each stream, histograms of the latency distribution, statistics of the throughput and an extensive tracing of registration, reservation, data transfer, de-registration, and error reporting. A major invention of this library is that networks can be constructed by simply configuring spreadsheets and tables.
