DDR5 DIMM Memory Model

DDR5 DIMM Memory Model provides an smart way to verify the DDR5 DIMM component of a SOC or a ASIC. The SmartDV's DDR5 DIMM memory model is fully compliant with standard DDR5 DIMM Specification and provides the following features. Better than Denali Memory Models.

DDR5 DIMM Memory Model is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

DDR5 DIMM Memory Model comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
