DDR4 DFI Verification IP provides an smart way to verify the DDR4 DFI component of a SOC or a ASIC. The SmartDV's DDR4 DFI Verification IP is fully compliant with standard DFI Specification and provides the following features.
DDR4 DFI Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
DDR4 DFI Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
