|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.

|Workload-tuned cores seeing greater interest|
Optimizing the instruction set and RTL of a design implements the exact resources necessary, and minimizes power consumption by omitting unnecessary functional blocks from the core. Processor Designer brings several toolsets together into a single environment to aid in understanding the underlying workload in data and compute intensive algorithms like vision, and tuning a core appropriately to get the job done.

|Advanced Virtualization Tools for Development of Automotive Applications: Synopsys|
In the automotive industry, millions of lines of code must be written, tested and thoroughly debugged to ensure that new vehicles meet performance requirements and buyer expectations. Due to tight production schedules, complex software must be developed before the actual hardware becomes available. Synopsys, a Renesas technology partner and a global leader in EDA tools and semiconductor IP, helps system engineers overcome this challenge.

|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.
