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. “Synopsys VIP for USB4 strengthens the USB ecosystem and facilitates early adoption and rapid development of the high-performance next-generation USB architecture.”
