Power And Signal Line Electromigration Design And Reliability Validation Challenges
By Various Writers - 14 Jun, 2012 - Comments: 0

This white paper describes EM integrity analysis for power and signal lines. It outlines the various process and design trends that are increasing the likelihood of EM-induced failures in a design and looks at conventional verification techniques for EM integrity and contrasts those with what is required for advanced process nodes.

The Brave New World Of Modeling TSVs
By Ed Sperling - 26 May, 2012 - Comments: 0

By Ann Steffora Mutschler With 2D ICs the prevailing notion has been that wire parasitics are relatively self-contained with the exception of very advanced designs running at hundreds of gigahertz. For the most part, the package designer and IC designer lived in their own separate worlds. With the advent of chip stacking using through silicon vias (TSVs), those worlds are being thrust together... » read more

New Power Standards Ahead
By Ed Sperling - 10 May, 2012 - Comments: 0

By Ed Sperling Standards groups are beginning to look at power and other physical effects much more seriously in the wake of the dueling power formats—UPF and CPF—that have caused angst across the design industry. To put it in perspective, when CPF and UPF were first introduced power was something of an afterthought in design. At 65nm it ceased to be something that could be dealt with l... » read more

The Next Steps
By Aveek Sarkar - 10 May, 2012 - Comments: 0

By Aveek Sarkar Remaining competitive in today’s semiconductor market means IC designers must meet performance, power and price targets for their design, regardless of the end application. Meeting these mutually conflicting goals requires enlisting the use of several architectural and design techniques, including three-dimensional (3D) or stacked-die architectures that can help meet perfo... » read more

Mechanical Meets Electrical
By Ed Sperling - 09 Feb, 2012 - Comments: 0

By Ed Sperling For the first part of the 20th century mechanical engineering dominated almost everything in technology. For the second half, once the transistor and the integrated circuit became well entrenched, those two disciplines largely divided up the tech market. More recently, however, they are being forced to collaborate in teams that historically had nothing in common. While the co... » read more

A Smart System Technology Renaissance
By Margaret Schmitt - 09 Feb, 2012 - Comments: 0

By Margaret Schmitt Leonardo da Vinci invented fantastic machines to revolutionize how man would live, work, wage war, and travel. Describing how he conceived these designs he said, “A painter should begin every canvas with a wash of black, because all things in nature are dark except where exposed by the light.” We currently are experiencing a renaissance of our own, with the rise of s... » read more

Electronic Power And Thermal Management
By Various Writers - 09 Feb, 2012 - Comments: 0

Highly complex systems require integrating a large number of electrical components within a very limited space. This creates challenges for power and thermal management not seen in previous generations of electronic systems. To be successful, plans must incorporate advanced power and thermal management strategies from the earliest stages of the design process and assess power and thermal issues... » read more

Better Power Planning
By Preeti Gupta - 12 Jan, 2012 - Comments: 0

By Preeti Gupta Making the right architectural decisions for controlling power consumption and ensuring power integrity requires early identification and quantification of varying current demands in a semiconductor design. Furthermore, low-power designs pose complexities for power verification, such as significant current surges caused by clock gating or power gating transitions. In last mo... » read more

Redefining Systems Around Power
By Ed Sperling - 06 Oct, 2011 - Comments: 0

By Ed Sperling Engineers have been talking about system-level power budgets since Moore’s Law reached 65nm, but as power becomes a critical element of any design with or without a plug the definition of what constitutes a system is changing. While most SoC engineers think of the system as an IC, power increasingly is playing a significant role in the subsystem, and even in the larger syst... » read more

Apache Update: Five Important Questions
By Ed Sperling - 11 Aug, 2011 - Comments: 0

By Ed Sperling It was supposed to be the first IPO since Magma went public in 2001. Instead, Apache was bought by Ansys in a deal that closed earlier this month—at a record pace for the EDA industry of less than two months since it was announced. So what exactly was behind the acquisition and why did Apache agree to sell? And what will become of Apache within the much larger Ansys? Low... » read more
