本文章现已有中文版供阅读车辆 ECU 开发：功能安全硬件调试功能安全测试在车辆 ECU 的开发过程中发挥着重要作用。不同阶段的测试有助于开发人员确保产品符合 ASIL 标准。硬件调试在其中扮演什么角色？综述。 Armin Stingl 著越来越多的电子控制单元（ECU）被应用到现代汽车中。这些嵌入式系统提供各种功能，从基本驾驶功能和安全措施到舒适和娱乐功能。根据功能的不同，ECU 中的故障会对乘客安全产生不同的影响。因此，ECU 按照不同的汽车安全完整性级别 (ASIL) 进行分类。例如：电动转向的 ECU 显然对安全性有很大影响，因为转向失灵可能导致乘客严重受伤甚至死亡。因此，该 ECU 被归类为 ASIL-D，即最高级别的安全要求。在开发具有这种 ASIL 分类的 ECU 时，必须从一开始就考虑到安全性。根据 ASIL-D，开发过程必须符合 ISO26262 标准规定的要求。因此，整个软件设计应遵循适当的开发方法。所使用的工具可能需要经过鉴定，以证明其适用于这一目的。然后 Read Article

Supporting diverse Debug protocols Active Probe Debug is your go-to companion for debugging, tracing, and testing a wide array of microcontroller architectures Read Article

Start development and initial integration work with virtual hardware Before a real target hardware is available, it makes sense to start development and initial integration work with virtual hardware. The increasing complexity of embedded software in general, time-to-market, and the early setup of test automation justify the use of such virtual hardware also called Virtual Target or Virtual Prototype. The TASKING winIDEA IDE for Synopsys VDK (Virtual Development Kit) and Synopsys Silver use the same front-end and Read Article

TASKING makes accessing highly integrated ECUs easy In the intricate world of automotive engineering, Electronic Control Units (ECUs) stand as the unassuming guardians of specific tasks within a vehicle's body. These tiny yet crucial components are the building blocks of today's automotive industry. However, their integration into a vehicle's infrastructure often renders them inaccessible, buried deep within the machinery, requiring laborious dismantling of surrounding hardware, a process that Read Article

Vehicle ECU development: Hardware debugging for functional safety Tests regarding functional safety play an important role in the development of vehicle ECUs. Tests at various stages help the developer to ensure conformity with ASIL standards. What role does hardware debugging play here? An overview. By Armin Stingl An increasing number of electronic control units (ECUs) are distributed in modern vehicles. These embedded systems provide various functions, from basic driving functions and safety measures to Read Article

Follow the Data To achieve freedom from interference as defined by ISO 26262 would be rather simple if all C modules were completely self-contained, i.e. only calling functions and referring variables within in the same module. But reality is different. Addresses of objects, passed as parameters, flow through the whole application. How to keep track of access violation in such a labyrinth of code? In order to assure freedom from interference The functional Read Article

The TASKING GTM C Compiler TASKING GTM Compiler Well, here we are at the final webinar in our series of seven. Thus far, I’ve shown you our tools that can help you develop quality and safe embedded software for Infineon TriCore family processors. This tool is not specifically for the TriCore. I’m sure you know that the TriCore family can include several ancillary cores such as the HSM, SCR, and PCP. Another core is available on the TriCore, and also on processors by other Read Article

The TASKING LAPACK Performance Libraries TASKING LAPACK Libraries for TriCore/AURIX Here is our fourth in our series of seven webinars. This product is different from our other tools: this is a library. The LAPACK Performance Libraries will enable you to call on its proven linear algebra processing capabilities to return quick and accurate solutions for your needs. With sensor processing and ADAS, more and more mathematical computations are being required…this Library can help you. The Read Article

The TASKING Embedded Profiler TASKING Embedded Profiler for TriCore/AURIX When talking about software development tools, a code profiler is seldom one of the tools mentioned, even though it can save a lot of debugging time and produce much better code. Profilers analyze your code and find underperforming code segments. This is very valuable when you need to determine why your code is not meeting specs or why certain segments are running slower than others. For many profilers Read Article

The TASKING Embedded Debugger TASKING Embedded Debugger for TriCore/AURIX As I mentioned in my first blog, when we think about embedded software development tools, we usually think of the compiler. But, just as important is the debugger. Few if any projects do not have some bugs that must be located and eliminated. In any major project, you have access to a high-end debugger that can not only verify your code function, but can also perform complex timing analyses that are so Read Article

The TASKING Safety Checker The TASKING Safety Checker for TriCore/AURIX Most of our customers are involved in developing safety-related systems for automobiles, agricultural machines, and other products that can present severe safety hazards for the people using them if something were to go wrong. Because of that, I think every one of us has an “I could hurt someone” reminder somewhere in our subconscious. We think about it all the time. Fortunately, some very sharp and Read Article

TASKING Compiler Tools for TriCore TASKING Compiler Tools for TriCore/AURIX As I mentioned in my first blog on our webinars, when we think of embedded software development, we first think about the compiler. Hopefully (!) most of your development time will be spent writing and compiling bug-free, perfect code! Before you watch the webinar, bear in mind that the TASKING compiler is an optimized and regularly maintained and improved compiler that offers many advantages over open Read Article

TASKING Toolset Overview TASKING: A Complete Toolset for Embedded Software Development for the Infineon TriCore/AURIX When we think about embedded software development tools, we always think of the compiler first. And, there is good reason: most of your development time is spent using the compiler tool as you write the code and as it is integrated and compiled for the completed product. But, in truth, as you progress through the project, you will use a number of tools Read Article

Undefined Behaviors in ISO-C: Their Effect on Your Embedded Software Part 2 In Part 1 of this blog, I defined what I mean by undefined behaviors and provided some examples. I also showed how difficult it is to manage some of these behaviors and tickled your interest by hinting that there may be a positive use to these behaviors. Let’s continue! How C compilers (ab)use undefined behavior The purpose of an optimizing compiler is to minimize the time needed to execute the program and to minimize the size of the executable Read Article

Undefined Behaviors in ISO-C: Their Effect on Your Embedded Software Part 1 Optimizing compilers sometimes give you...well, unexpected results. You have probably seen this before, but maybe wasn’t sure what happened and why. This two-part blog is about the undefined behaviors that exist in ISO-C, the way optimizing compilers make use of it, which is often not well-understood by programmers, and the unpredictable software bugs that result from it and frequently show up in code that is attempting security checks. Although Read Article

Self Driving Car Safety Statistics Support Early Implementation When I think about self-driving cars, the first question that pops into my mind is, “When are they going to get here?” I’m tired of driving myself around town and getting stuck in traffic! You might ask the same question if you are a software developer for autonomous vehicles or cars with advanced driver assistance systems (ADAS). Up until now, the answer has been, “When they’re extremely safe.” In the United States, the National Highway Traffic Read Article
