DFI GDDR6 Assertion IP provides an efficient and smart way to verify the DFI GDDR6 designs quickly without a testbench. The SmartDV's DFI GDDR6 Assertion IP is fully complian with standard DFI GDDR6 Specification.
GDDR6 DFI Assertion IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
GDDR6 DFI Assertion IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
