SGRAM Memory Model

Overview

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

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

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

Key Features

Supports for the following modes of burst type control.

Basic mode
Special mode
Random mode
Interrupt mode

Supports for burst terminate.
Supports the following burst order.

Sequential
Interleave

Supports for self refresh mode.
Supports data mask for write and block write.
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 full-timing as well as behavioral versions in one model.
Supports for all timing delay ranges in one model: min, typical and max.
Protocol checker fully compliant with SGRAM Specification IS42G32256-8pQ.pdf.
Models, detects and notifies the test bench of significant events such as transactions, warnings, timings and protocol violations.
Constantly monitors SGRAM behavior during simulation.
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 SGRAM designs.
Easy to use command interface simplifies monitor control and configuration.
Simplifies results analysis.
Runs in every major simulation environment.
