Wind River Simics Model Builder Essentials

This course provides engineers and system architects with a fast, cost-effective way to learn to use Wind River Simics Model Builder. Wind River Simics Model Builder is an add-on to the Wind River Simics system simulator that lets you create your own models, ranging from simple devices up to complex, multi-component systems.

After this course, participants will be able to do the following:

• Understand and follow the general device modeling process.
• Create device models in the device modeling language DML.
• Compile devices and test them for correct functionality.
• Understand and follow the general component modeling process.
• Create hierarchical component models in Python.
• Compile components and test them for correct functionality, including Simics features.

• Wind River Simics Model Builder for Simics 4.6

• Software developers and testers

Day 1

Device Modeling Process

• What to Model
• Talking About Abstraction
• The Process
• Talking About Performance

Device Modeling Tools

• Workspace Setup Tool
• DMLC Compiler
• Using GNU Make

LAB: Creating a Skeleton Device Model

• Create a workspace and a device skeleton, and invoke the build and test framework.

DML Basics

• Language Fundamentals
• Parameters, Methods, Templates
• Attributes, Banks, Registers
• Connects, Interfaces, Implements, Ports

LAB: Adding Interfaces to a Skeleton Device Model

• Add register banks, bit fields, and signal ports to the device skeleton.

Device Testing

• Test Suites
• Creating Devices Outside Components
• An Elaborate Example

LAB: Initial Testing

• Add tests to the test suite, run the test suite, and fix bugs found by the tests.

LAB: Adding and Testing Basic Functionality

• Add register access functionality, attributes, and connects, and test the added functionality.

Advanced Device Modeling Topics

• Using Events
• Miscellaneous Statements and Expressions
• Interfacing to C
• Device-Specific CLI Commands

LAB: Implementing Advanced DML Concepts

• Finalize the device by adding exception handling, implementing interfaces, and using events to handle timed behavior, and testing the completed device.

Day 2

System Modeling Process

• System Modeling Terminology
• The Process
• Available Tools

Component Modeling

• Component Fundamentals
• Getting Device Information
• Component Attributes
• Handling Slots and Connectors
• Compiling and Creating Components
• Testing Components
• Making Components GUI-compatible

LAB: Planning a Simics System Model

• Understand the system requirements and how to model them in Simics.

LAB: Modeling a System on Chip

• Create a component skeleton, add and connect devices, and compile and test the component.

LAB: Modeling a Board

• Create a component skeleton, add and connect the system on chip and devices, create machine scripts, and test the board by executing software on the virtual board.

LAB: Testing Simics Features

• Test checkpointing and reverse execution using the newly created virtual board.
