|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.

|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.

|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.

|Virtual Platforms: Breaking New Grounds|
The case for developing and using virtual platforms (VPs) has now been made. If developers of complex HW/SW systems are not using VPs for their current design, complexity of next generation designs demands for their adoption. This paper summarizes a special session focused on the latest applications and latest use cases for VPs. It gives an overview of where this technology is going and the impact on complex system design and verification.

|IEEE Approves Revised IEEE 1666™ "SystemC Language" Standard|
IEEE announced that the IEEE Standards Association (IEEE-SA) Standards Board has approved a revised version of the IEEE 1666™ "Standard SystemC Language Reference Manual," which specifies SystemC, the high-level design language used in the design and development of electronic systems. The new version of IEEE 1666 encompasses many enhancements, notably the support for transaction-level modeling (TLM), a critical approach to enable higher level and more efficient design of complex integrated circuits (ICs) and system-on-chips (SoCs).
