FPMRAM Memory Model

Overview

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

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

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

Key Features

Supports FPMRAM memory devices from all leading vendors.
Supports 100% of FPMRAM protocol standard.
Supports all the FPMRAM commands as per the specs.
Supports up to 16 MB device density.
Supports the X16 device mode operation.
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 Byte Write and Byte Read operation via two CAS.
Supports following refresh intervals.

512 cycles/8ms
1024 cycles/16ms

Supports for following Refresh Mode:

RAS-Only
CAS-before-RAS (CBR)
Hidden

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.
Quickly validates the implementation of the standard FPMRAM specification.
Protocol checker fully compliant with FPMRAM Specification.
Constantly monitors FPMRAM behavior during simulation.
Models, 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 FPMRAM designs.
Easy to use command interface simplifies monitor control and configuration.
Simplifies results analysis.
Runs in every major simulation environment.
