The ISO 26262 automotive safety standard requires evaluation of safety goal violations due to random hardware faults to determine diagnostic coverages (DC) for calculating safety metrics. Injecting faults using simulation may be time-consuming, tedious, and may not activate the design in a way to propagate the faults for testing. With formal verification, however, faults are easily categorized by structural analysis providing a worst-case DC.
IoT application development has already evolved largely into an integration problem. Developers can find all manner of IoT hardware devices that provide a growing number of near drop-in solutions for populating an IoT system's layers of terminal sensor nodes and edge computing devices.
A desktop-based test harness can help developers make progress in testing code littered with RTOS API calls.
In this article, the process of selecting an operating system for an embedded system is outlined and reviewed. Colin Walls of Mentor Graphics discusses whether or not you need to use an OS and if so, whether it will be a free, open source version, commercial, or a custom designed one. Then he drills down and looks at the pros and cons of various features you will need in the OS you have chosen.
SoC designs are large designs made by combining other large designs. A typical SoC has many communication pathways and a large amount of parallel activity. In order to debug these kinds of designs effectively new approaches must be taken. This paper discusses the requirements for effective debug in the face of today's large SoCs, outlining real world example and making some recommendations for easier solutions. This includes transaction based debug, with special attribute recording. These special attributes help identify "connected" transactions.
The replacement of a function call by a copy of the code of the function can be an effective optimization, particularly if execution speed is the priority. This article takes a look at how inlining works, when it can be effective, and how it may happen automatically in C and C++.
