Time Synchronization in the Nanosecond Range with IXXAT Software

Adding to the existing and proven IXXAT IEEE 1588 solutions, HMS now presents protocol software for IEEE 802.1AS - the first commercially available software package for highly accurate time synchronization of AVB and TSN networks. IEEE 802.1 AS is an adapted version of the IEEE 1588 profile - specially designed for AVB and TSN systems (audio/video broadcasting and time sensitive networking). As the most important core technology for AVB and TSN systems, IEEE 802.1AS enables high-precision time synchronization of devices and systems.

Using the IXXAT IEEE 802.1AS protocol software, customers benefit from a proven and tested software package as well as from a professional product maintenance and further development.

The 802.1AS protocol software offered by HMS comes as ANSI C code - inspired by MISRA-C - and has a modular structure with a clear separation of the media dependent and media independent layers. This enables easy porting and fast implementation into various target systems. As a time-aware, slave-only end station, the software is the receiver of time-synchronization information provided by a grandmaster and enables synchronization of local Real Time Clocks  (RTCs). The software supports the Best Master Clock algorithm, which can be optionally disabled.

In addition to meeting the requirements of AVB and TSN systems, special needs within automotive systems are supported such as fast synchronization times (< 1 microsecond within one second) and optimization of memory usage.

Besides other IXXAT IEEE 1588 products such as the IEEE 1588 protocol software, the IP Core and the manager tool, HMS also offers a wide range of services based on the deep experience in the IEEE 1588 area. HMS assists the customers in all phases of the development process, from consulting and specification, to implementation, target adaptation and testing of the final product.
