COURSE DESCRIPTION

The Wind River® Simics Device Modeling course provides engineers and system architects with the knowledge they need to use Wind River Simics Model Builder for device modeling. Wind River Simics Model Builder is an add-on to the Wind River Simics system simulator that lets you create your own device models to use in system components. This course explains how to use the Simics Device Modeling Language (DML) to describe hardware devices like counters, DMA engines, or interrupt controllers. Devices can then be used to assemble complete systems (covered in the Wind River Simics System Modeling course).

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

• Understand and follow the general device modeling process
• Create device models in DML
• Compile devices and test them for correct functionality

Products Supported

• Wind River Simics Model Builder for Simics 6
• Wind River Simics Model Builder for Simics 5
• Wind River Simics Model Builder for Simics 4.8

Course Format

• This two-day, expert-led course consists of lectures and lab sessions.
• Attendees use Wind River Simics Model Builder for Simics to gain experience with the topics presented.
• Participants write, compile, and test DML code to model custom devices.
• Participants receive individual guidance from an expert engineer who has extensive experience with Wind River technologies.
