|Safer Car Design Demands New Testing Approaches|
The automotive market is facing tough challenges when it comes to recalls. It seems that every month (if not week) brings a long list of new recalls. It's not that recalls did not exist in the past, but it seems that their numbers, types, and obvious visibility through the media have significantly increased.

|Non-separation of Power and Performance|
How much power does a system consume? The simplistic path to power estimation for a system used to be tossing a few metrics – standby, typical, worst case, with figures pulled from a datasheet, simulation, or physical measurement – into a spreadsheet. After filling the remaining holes with SWAG (scientific wild-ass guesses), and summing things up, there was a bottom line.

|When and Where To Use Virtual Prototypes|
While it’s technically possible to create a virtual prototype that reflects an entire SoC, it isn’t always the best choice. Just because something is technically possible doesn’t always mean it should be done. This definitely holds true currently when it comes to virtual prototypes, which have gotten a lot of attention for their potential in the SoC design process—especially for concurrent software development.

|Architecting for Efficiency|
To design an SoC most efficiently, there are many considerations to keep in mind. By definition, to be efficient is to perform or function in the best possible manner with the least waste of time and effort; having and using requisite knowledge, skill, and industry. As this relates to SoC design today, achieving the highest level of efficiency is a challenge with many dimensions.

|Book review: “shift left” with virtual prototypes|
Synopsys has just released a new book titled “Better Software. Faster!” extolling the benefits of virtual prototyping for embedded software development. In a refreshing approach, editor Tom De Schutter has embedded software developers from companies across several industries tell the story of how they are succeeding with virtual prototyping. For those heavily involved in embedded software development or project management, those new to the idea of virtual prototyping, or management teams deeply interested in on-time delivery, this is a solid read.

|Synopsys’ ESL Power Analysis|
This article addresses the question, "what tools or methods do architects and developers have or should have to define a realistic power budget at the system level?" System-level tools for power-aware virtual prototyping and power-efficient programmable hardware design are available today, enabling architects and developers to define realistic power budgets for their SoC hardware and software much earlier in the development cycle.

|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.
