Software Development Using Full System Simulation with Freescale QorIQ Communications Processors

What Is Wind River Simics? Simics is a full system simulator used by software developers to simulate the hardware of large and complex electronic systems. Target Hardware Simics Simulate any size target system. Run unmodified target binaries. Use groundbreaking debugging techniques. Simics allows you to break the rules of embedded development. of 4 2013 Wind River. All Rights Reserved.

Why do it Virtually? Manipulate your systems in ways that you can t with physical hardware Control time and space Debug the system as a whole Full accessible Fully customizable Archivable and Restorable Repeatable 6 2013 Wind River. All Rights Reserved.

Imagine If You Could Reduce your time-to-market by 66%. Reduce your debug time by 35%. Reduce your development target costs by 45%. Debug software before hardware exists Try out your software on a new chip before silicon exists Integrate and test your system before the system exists Enable agile and iterative development Easily manage and configure large systems-of-systems Easily debug large systemsof-systems Provide target hardware for every team member Try out several hardware configurations before you commit to one Equip sales and tech support with inexpensive and flexible virtual targets 7 2013 Wind River.

Imagine If You Could Shift your schedules left. Enable agile and iterative development parallelize work. Begin software development before hardware is available. Replace big-bang integration with incremental integration. Have full system available months in advance of target hardware. 8 2013 Wind River. All Rights Reserved.

Simics Analyzer Demonstrating two different ways to handle a hardware device. The red alternative is using a regular Linux device driver and spends most of its time in the kernel The green alternative is accessing the hardware directly from user space using an mmap() setup, leading to very little kernel time (and better latency).
