|IP Power Models Enable Energy-Aware System-Level Design|
The way a platform is used determines how much energy it consumes, requiring a holistic approach to energy management. Energy efficiency is one of the primary design metrics for heterogeneous multi-core mobile platforms, and the very real threat of dark silicon reinforces the fact that we must manage energy consumption in these platforms intelligently.

|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.

|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.

|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.
