LPDDR4 Memory Model

Overview

LPDDR4 Memory Model provides an smart way to verify the LPDDR4 component of a SOC or a ASIC. The SmartDV's LPDDR4 memory model is fully compliant with standard LPDDR4 Specification and provides the following features. Better than Denali Memory Models.

LPDDR4 Memory Model is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

LPDDR4 Memory Model comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
