USART Verification IP provides an smart way to verify the USART component of a SOC or a ASIC. The SmartDV's USART Verification IP is fully compliant with standard USART ds8251 Specification and provides the following features.
USART Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
USART Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
