RLDRAM Memory Model

Overview

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

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

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

Key Features

  • Supports RLDRAM memory devices from all leading vendors.
  • Supports 100% of RLDRAM protocol standard.
  • Supports all the RLDRAM commands as per the specs.
  • Supports the following devices.
    • X32
    • X16
  • Supports cyclic bank addressing for maximum data out bandwidth.
  • Supports non-multiplexed addresses.
  • Supports non-interruptible sequential burst of two (2-bit prefetch) and four (4-bit prefetch).
  • Supports 600 Mb/s/p data rate.
  • Supports programmable Read Latency (RL) of 5-8.
  • Supports data valid signal (DVLD) activated as read data is available.
  • Supports data Mask signals (DM0/DM1) to mask first and second part of write data burst.
  • Supports IEEE 1149.1 compliant JTAG boundary scan.
  • Supports internal auto precharge.
  • Supports programmable clock frequency of operation.
  • Supports all types of timing and protocol violation detection.
  • Constantly monitors RLDRAM behavior during simulation.
  • Protocol checker fully compliant with RLDRAM Specification.
  • Models, detects and notifies the test bench of significant events such as transactions, warnings, timings and protocol violations.
  • Built in functional coverage analysis.
  • Supports callbacks, so that user can access the data observed by monitor.

Benefits

  • Faster testbench development and more complete verification of RLDRAM designs.
  • Easy to use command interface simplifies monitor control and configuration.
  • Simplifies results analysis.
  • Runs in every major simulation environment.
