USB4 is the next generation of the Universal Serial Bus and a major update to the interface in speed and functionality. USB4 has incorporated Thunderbolt 3 capabilities, which extends support of USB interface to existing PCIE, and DisplayPort over the same USB Type-C connector. USB4 doubles the maximum overall throughput from 20Gbps to 40Gbps enabling optimized HD video and data transfer simultaneously. USB4 enables many applications using USB Type-C, which already supports power delivery, USB 3.2, USB 2.0 and other alternative protocols.

¡°USB4 represents a significant specification update that will require a robust certification program to ensure delivery of compliant and interoperable USB devices in the consumer market,¡± said USB-IF president and chief operating officer Jeff Ravencraft. ¡°²ÝÁñÉçÇø VIP for USB4 strengthens the USB ecosystem and facilitates early adoption and rapid development of the high-performance next-generation USB architecture.¡±

With multiple protocols being supported, verification of a complete USB4 design will involve USB 3.x, PCIE, DisplayPort, USB4 (lane adapter and router functions). ²ÝÁñÉçÇø has developed a comprehensive ??USB4 verification subsystem, being already used by Early Adopters planning to release their first USB4 applications. ²ÝÁñÉçÇø Industry¡¯s first USB4 verification subsystem reuses proven VIPs for USB 3.x, PCIE and DisplayPort and helps users quickly integrate a complete USB4 DUT , for more details refer
