|Advanced Fault Injection Methods for Safety Critical Systems|
ISO 26262 is a functional safety standard that replaces the older and more generic IEC 61508 standard for passenger vehicles. ISO 26262 addresses hazards caused by malfunctioning behavior of electric and electronic safety related systems.
The standard provides a well-defined, automotive-specific safety life cycle. It also provides an automotive-specific, risk-based approach focused on automotive safety integrity levels, ASIL. Finally, ISO 26262 provides requirements and recommended methods for validation of the safety levels.

| So, Just What Is ESL?|
The challenges now facing semiconductor companies are huge, and they don't stop with complexity. In tiny geometries, with as many as tens of millions of gates, today's SOCs are likely to be multicore and to have on them up to 100 IP blocks. The clincher, though, is that despite all that complexity, silicon has become almost a commodity with software having become the differentiator.

|Software Testing for Safety-critical Automotive Systems|
The automotive industry faces a significant challenge: to release cars with zero software defects. The number of recalls and redesigns due to software problems illustrates the magnitude of the challenge – they have grown exponentially over the last decade. There are major economic implications for manufacturers since the cost of recalling a vehicle can be huge, especially when the issue affects the integrity of the brand. - Victor Reyes, Synopsys

|Being Different Is Bad|
Today's SoCs contain as much as 80% existing IP that either has been re-used from previous projects or obtained from a third party. Models are created of this hardware IP, as well as new portions of the design, in order to create a virtual prototype that allows the engineering team to see the complete system by running software and applications.

|The Trouble With Models|
Models and modeling concepts seem to be on the tip of every tongue these days. Once the promise of sparking true ESL design, the use of system-level models has settled into something more like enabling software development.
There is also talk of leveraging models across the supply chain, but is this really possible yet? The concept of doing this incremental refinement and re-using models across multiple use cases is starting to gain a lot of interest.

|Software Agnostic Approaches to Explore Pre-silicon System Performance|
A new modeling methodology is proposed to improve performance validation at an early stage in the design cycle of systems dedicated to handheld devices. Hardware models are typically available early in the chipset development cycle, but software, such as multimedia applications, may not be developed until after the ASIC is designed. An alternative source of simulation stimulus must be found so that hardware models can be exercised in the absence of such software. This paper describes three approaches that overcome this dependency and enable the validation of application processor performance at the architecture stage of silicon design: high-level software models, trace-driven characterization, and statistical traffic models. Correlation between actual measurements and simulation outputs demonstrates that these methods provide adequate accuracy for performance validation.
