  • Automotive Foundational Software Solutions for the Modern Vehicle Overview
    www.qnx.com AUTOMOTIVE FOUNDATIONAL SOFTWARE SOLUTIONS FOR THE MODERN VEHICLE OVERVIEW Dear colleagues in the automotive industry, We are in the midst of a pivotal moment in the evolution of the car. Connected and autonomous cars will have a place in history alongside the birth of industrialized production of automobiles, hybrid and electric vehicles, and the globalization of the market. The industry has stretched the boundaries of technology to create ideas and innovations previously only imaginable in sci-fi movies. However, building such cars is not without its challenges. AUTOMOTIVE SOFTWARE IS COMPLEX A modern vehicle has over 100 million lines of code and autonomous vehicles will contain the most complex software ever deployed by automakers. In addition to the size of software, the software supply chain made up of multiple tiers of software suppliers is unlikely to have common established coding and security standards. This adds a layer of uncertainty in the development of a vehicle. With increased reliance on software to control critical driving functions, software needs to adhere to two primary tenets, Safety and Security. SAFETY Modern vehicles require safety certification to ISO 26262 for systems such as ADAS and digital instrument clusters. Some of these critical systems require software that is pre-certified up to ISO 26262 ASIL D, the highest safety integrity level. SECURITY BlackBerry believes that there can be no safety without security. Hackers accessing a car through a non-critical ECU system can tamper or take over a safety-critical system, such as the steering, brakes or engine systems. As the software in a car grows so does the attack surface, which makes it more vulnerable to cyberattacks.

  • Real-Time Operating System Modelling and Simulation Using Systemc
    Real-Time Operating System Modelling and Simulation Using SystemC Ke Yu Submitted for the degree of Doctor of Philosophy Department of Computer Science June 2010 Abstract Increasing system complexity and stringent time-to-market pressure bring chal- lenges to the design productivity of real-time embedded systems. Various System- Level Design (SLD), System-Level Design Languages (SLDL) and Transaction- Level Modelling (TLM) approaches have been proposed as enabling tools for real-time embedded system specification, simulation, implementation and verifi- cation. SLDL-based Real-Time Operating System (RTOS) modelling and simula- tion are key methods to understand dynamic scheduling and timing issues in real- time software behavioural simulation during SLD. However, current SLDL-based RTOS simulation approaches do not support real-time software simulation ade- quately in terms of both functionality and accuracy, e.g., simplistic RTOS func- tionality or annotation-dependent software time advance. This thesis is concerned with SystemC-based behavioural modelling and simu- lation of real-time embedded software, focusing upon RTOSs. The RTOS-centric simulation approach can support flexible, fast and accurate real-time software tim- ing and functional simulation. They can help software designers to undertake real- time software prototyping at early design phases. The contributions in this thesis are fourfold. Firstly, we propose a mixed timing real-time software modelling and simula- tion approach with various timing related techniques, which are suitable for early software modelling and simulation. We show that this approach not only avoids the accuracy drawback in some existing methods but also maintains a high simu- lation performance. Secondly, we propose a Live CPU Model to assist software behavioural timing modelling and simulation.
