LPDDR5 Memory Model provides an smart way to verify the LPDDR5 component of a SOC or a ASIC. The SmartDV's LPDDR5 memory model is fully compliant with standard LPDDR5 Specification and provides the following features. Better than Denali Memory Models.
LPDDR5 Memory Model is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
LPDDR5 Memory Model comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
