eUSB VIP

Description and Features

A SOC or ASIC's eUSB component may be intelligently verified with the help of eUSB Verification IP. It offers backwards compatibility with prior USB 1.0 and 2.0 standards versions. The USB Verification IP complies in full with both the USB Revision 2.0 Specification Rev.1.1 and the Embedded USB2 (eUSB2) Physical Layer Supplement. There are several transfer speeds with eUSB VIP. Of which high speed (480 Mbit/s), full speed (12 Mbit/s), or low speed (1.5 Mbit/s) logically implies. SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E, and non-standard verification environments all natively support eUSB Verification IP. The Smart Visual Protocol Debugger (Smart ViPDebug), a GUI-based debugger to expedite debugging, is an optional component of the eUSB Verification IP.
