LPDDR2 Memory Model

LPDDR2 Memory Model

LPDDR2 Memory Model provides an smart way to verify the LPDDR2 component of a SOC or a ASIC. The SmartDV's LPDDR2 memory model is fully compliant with standard LPDDR2 Specification and provides the following features. Better than Denali Memory Models.

LPDDR2 Memory Model is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

LPDDR2 Memory Model comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.

Features
  • Supports LPDDR2 memory devices from all leading vendors.
  • Supports 100% of LPDDR2 protocol standard JESD209-2E and JESD209-2F.
  • Supports all the LPDDR2 commands as per the specs.
  • Supports up to 32GB device density
  • Supports the following devices.
    • X8
    • X16
    • X32
  • Supports all speed grades as per specification.
  • Quickly validates the implementation of the LPDDR2 standard JESD209-2E and JESD209-2F.
  • Supports for Programmable Write latency and Read latency.
  • Supports for Programmable burst lengths: 4, 8, and 16.
  • Supports for the following Burst Types,
    • Sequential
    • Interleave
  • Checks for following
    • Check-points include power up, initialization and power off rules,
    • State based rules, Active Command rules,
    • Read/Write Command rules etc.
    • All timing violations.
  • Supports for All Mode registers/Control programming.
  • Supports for NVM device.
  • Supports for ZQ/DQ calibration.
  • Supports for Overlay window Enable/Disable.
  • Supports for Write data Mask.
  • Supports for Power Down and Deep Power Down features.
  • Supports for Auto Precharge option for each burst access
  • Supports for input clock stop and frequency change.
  • Supports for full-timing as well as behavioral versions in one model.
  • Supports for all timing delay ranges in one model: min, typical and max.
  • Optional Partial Array Self Refresh and Temperature Compensated Self Refresh
  • Protocol checker fully compliant with LPDDR2 Specification JESD209-2E and JESD209-2F.
  • Constantly monitors LPDDR2 behavior during simulation.
  • Model detects and notifies the test bench of significant events such as transactions, warnings, timing 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 LPDDR2 designs.
  • Easy to use command interface simplifies monitor control and configuration.
  • Simplifies results analysis.
  • Runs in every major simulation environment.
