LPDDR DFI Assertion IP

Overview

DFI LPDDR Assertion IP provides an smart way to verify the ARM DFI LPDDR component of a SOC or a ASIC. The SmartDV's DFI LPDDR Assertion IP is fully compliant with standard DFI LPDDR Specification and provides the following features.

LPDDR DFI Assertion IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

LPDDR DFI Assertion IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
