XMBus Verification IP

XMBus(Extended Management Bus) Verification IP provides an smart way to verify the XMBus bi-directional two-wire bus. The SmartDV's XMBus Verification IP is fully compliant with version 0.5 of the XMBus Specifications and provides the following features.

XMBus Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

XMBus Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
