GDDR5 Assertion IP provides an efficient and smart way to verify the GDDR5 designs quickly without a testbench. The SmartDV's GDDR5 Assertion IP is fully compliant with standard GDDR5 Specifications and provides the following features.
GDDR5 Assertion IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
GDDR5 Assertion IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
