A Cost-Effective Model-Based Approach For Developing ISO 26262 Compliant Automotive Safety-Related Applications


Automotive manufacturers and their suppliers increasingly need to follow the objectives of ISO 26262 as it is now state-of-the art and as it is the case that an ever increasing number of active and passive safety systems are developed within cars. This has increased the need to define a safe system development process. This paper proposes a model-based approach including automatic and certified... » read more

Turning Signal Integrity Simulation Inside Out


So what does it mean to turn signal integrity simulation inside out? Modern simulation has physics-based solvers in the foreground supported by circuit and system simulation rather than the other way around. All electronic design is fundamentally based on Maxwell’s equations, so naturally the most rigorous way to deliver accurate simulation of high-performance systems is to solve those equ... » read more

Electrothermal Mechanical Stress Reference Design Flow For Printed Circuit Boards And Electronic Packages


This paper presents a reference design flow for solving the electrical, thermal and mechanical challenges of a printed circuit board (PCB) using simulation tools from ANSYS. This approach can be utilized for all electrical CAD (ECAD) types such as IC packages, touch panel displays, and glass and silicon interposers. The authors followed this reference design flow for analyzing a PCB virtual pro... » read more

The Best Of Both Worlds


Fidelity and accuracy are critical in computational fluid dynamics (CFD) simulation. After all, physical prototyping and testing can only be reduced if one can expect accurate simulation results. But up to now, high fidelity, high accuracy results have come with a price. Complex, realistic geometries have required hours of manual effort to clean up the model and prepare the mesh. Users have bee... » read more

An Open Solution For Systems And Embedded Software Simulation


This paper describes a complete Systems and Embedded Software Validation & Verification workflow that uses SCADE for modeling and simulating the controller software and a combination of other modeling tools for plant simulation. It introduces the Scade language and the SCADE Suite toolset that includes a (certified) code generator for producing the controller software. It then describes how ... » read more

Cloud Computing Best Practices For Engineering Simulations


Rapid growth in the use of engineering simulation tools – and in the demand for high performance computing (HPC) – is driving interest in cloud computing. Using the cloud for simulation presents unique challenges with different solution types required for specific use cases. This white paper describes eight best practices for cloud deployments that are fundamentally related to simulation... » read more

Breakthrough Energy Innovation: Ambition And Urgency


The easy answers to developing products for more sustainable energy designs have already been found, so only the toughest challenges remain to be solved. Innovative improvements to existing products are leading to increased complexity, while disruptive developments push engineers into uncharted design spaces. Either path — increased complexity or unknown territory — requires greater design ... » read more

Simulating Composite Structures


Composites provide new solutions for manufacturers looking for stronger, lighter and more cost-effective materials. At the same time, they pose new modeling and manufacturing challenges because of the nature of the materials. With the right simulation tools, designers can account for residual stresses, predict performance, analyze reliability and potential failures, optimize construction, and e... » read more

Cluster Scalability Of ANSYS Fluent 12.0 For A Large Aerodynamics Case On The Darwin Supercomputer


This work examines the parallel scalability characteristics of commercial CFD software ANSYS FLUENT 12 for up to 256 processing cores, for transient CFD simulations that are heavy in I/O relative to numerical operations. In studies conducted with engineering contributions from the University of Cambridge and ANSYS, the Linux HPC environment named Darwin combined an Intel Xeon cluster with a P... » read more

Qualified Code Generation Greatly Reduces Cost Of Safety-Critical Automotive Software


As automobile electronics become more prevalent and sophisticated, ensuring the reliability of the embedded software code within those systems becomes critical to the safety of passengers and pedestrians. The development of an ISO 26262 qualified code generator helps automotive OEMs and suppliers drastically reduce development costs while ensuring that their embedded software applications will ... » read more
