Excelfore has established itself as a leading provider of AVB/TSN software solutions, including clock synchronization and networking architectures. Over the past decade, the company has successfully delivered more than two dozen projects to major OEMs. In building these production-ready software stacks, Excelfore also created a wide range of supporting tools—such as advanced test frameworks and traffic pattern injectors—to strengthen its development and quality assurance processes. Excelfore is recognized as one of only four globally authorized test and certification laboratories under the Avnu standards organization.
Excelfore offers a robust portfolio of AVB/TSN test tools for validating next-generation in-vehicle networks. The 1) Media Test Tool enables TSN streaming and full command/control of devices under test. The 2) AccuMedia Test Tool, built on AM62D SoC and CDCE6214-Q1, delivers ultra-precise AVB/TSN audio-media clock synchronization. For zonal architectures, the 3) Harness for Zonal Controllers supports CAN, CAN-FD, and automotive Ethernet (1G/100Mb/10Mb), providing a comprehensive environment for controller validation.
