MRAM Memory Model

Overview

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

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

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

Output Disabled
Not Selected

Quickly validates the implementation of the MRAM standard MR2A16A and MR0A08B.
Supports Flexible data bus control - 8 bit or 16 bit access.
Supports Flexible density of 4Mb or 16Mb
Checks for following

Check-points include power up, initialization and power off rules
Read/Write byte Command rules etc.,
All timing violations

Supports all types of timing and protocol violation detection..
Protocol checker fully compliant with MRAM Specifications MR2A16A and MR0A08B.
Constantly monitors MRAM behavior during simulation.
Protocol checker fully compliant with MRAM Specification.
Models, detects and notifies the test bench of significant events such as transactions, warnings, and timing and protocol violations.
Built in functional coverage analysis.
Supports Callbacks, so that user can access the data observed by monitor

Benefits
