GDDR3 Memory Model

Overview

GDDR3 Memory Model provides an smart way to verify the GDDR3 component of a SOC or a ASIC. The SmartDV's GDDR3 memory model is fully compliant with standard GDDR3 Specification and provides the following features. Better than Denali Memory Models.

GDDR3 Memory Model is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

GDDR3 Memory Model comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.

Key Features

Quickly validates the implementation of the GDDR3 standard GDDR3 Specification.
Supports for programmable clock frequency of operation.
Supports for all types of timing and protocol violation detection.
Supports for All Mode register programming.
Supports for 8 bank operation.
Supports for Nominal and dynamic on-die termination (ODT) for data, strobe and mask signals.
Checks for following

Check-points include power on, Initialization and power off rules,
State based rules, Active Command rules,
Read/Write Command rules etc.
All timing violations.
