Low Latency DRAM Memory Model

Overview

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

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

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

Key Features
