UART Verification IP

Overview

UART Verification IP provides an smart way to verify the UART component of a SOC or a ASIC. The SmartDV's UART Verification IP is fully compliant with standard UART 16550 Specification and provides the following features.

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

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