HyperBus Memory Model

Overview

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

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

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

Supports all types of timing and protocol violation detection.
Constantly monitors HyperBus behavior during simulation.
Protocol checker fully compliant with Cypress HyperBus Specification.
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 HyperBus designs.
Easy to use command interface simplifies monitor control and configuration.
Simplifies results analysis.
Runs in every major simulation environment.
