DDR2 Memory Model provides an smart way to verify the DDR2 component of a SOC or a ASIC. The SmartDV's DDR2 memory model is fully compliant with standard DDR2 Specification and provides the following features. Better than Denali Memory Models.
DDR2 Memory Model is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
DDR2 Memory Model comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
