Thermal Challenges And Moore’s Law


Steven Woo, fellow and distinguished inventor at Rambus, looks at the evolution of graphics cards over a couple of decades and how designs changed to deal with more graphics and more heat, and why smaller, faster and cheaper doesn’t apply in this market. » read more

Pushing Memory Harder


In an optimized system, no component is waiting for another component while there is useful work to be done. Unfortunately, this is not the case with the processor/memory interface. Put simply, memory cannot keep up. Accessing memory is slow, and it can consume a significant fraction of the power budget. And the general consensus is this problem is not going away anytime soon, despite effort... » read more

Less Food, More Thought


A trillion "things" are expected to be connected to the Internet sometime in the next decade. No matter how power-efficient these things are, they probably will require enough coin-sized lithium batteries to drain the world's supply of element No. 3 on the Periodic Table. They also will increase the demand for power everywhere, and that's even before tacking on electric vehicles, the edge, robo... » read more

Using Emulators For Power/Performance Tradeoffs


Emulation is becoming the tool of choice for power and performance tradeoffs, scaling to almost unlimited capacity for complex chips used in data centers, AI/ML systems and smart phones. While emulation has long been viewed as an important but expensive asset for chipmakers trying to verify and debug chips, it is now viewed as an essential component for design optimization and analysis much ... » read more

Less Margin, More Respins, And New Markets


Semiconductor Engineering sat down to discuss the impact of multi-physics and new market applications on chip design with John Lee, general manager and vice president of ANSYS' Semiconductor Business Unit; Simon Burke, distinguished engineer at Xilinx; Duane Boning, professor of electrical engineering and computer science at MIT; and Thomas Harms, director EDA/IP Alliance at Infineon. What foll... » read more

The Growing Impact Of Portable Stimulus


It has been a year since Accellera's Portable Test and Stimulus Specification became a standard. Semiconductor Engineering sat down to discuss the impact it has had, and the future direction of it, with Dave Kelf, chief marketing officer for Breker Verification Systems; Larry Melling, product management director for Cadence; Tom Fitzpatrick, strategic verification architect for Mentor, a Siemen... » read more

Trading Off Power And Performance Earlier In Designs


Optimizing performance, power and reliability in consumer electronics is an engineering feat that involves a series of tradeoffs based on gathering as much data about the use cases in which a design will operate. Approaches vary widely by market, by domain expertise, and by the established methodologies and perspective of the design teams. As a result, one team may opt for a leading-edge des... » read more

Reducing Software Power


With the slowdown of Moore's Law, every decision made in the past must be re-examined to get more performance or lower power for a given function. So far, software has remained relatively unaffected, but it could be an untapped area for optimization and enable significant power reduction. The general consensus is that new applications such as artificial intelligence and machine learning, whe... » read more

Moving Beyond Assertions: An Innovative Approach to Low-Power Checking Using UPF Tcl Apps


This paper uses examples and case studies to demonstrate how to leverage UPF 3.0 information model TCL query functions (aka Tcl Apps) and tool provided CLI commands to do low-power checking of a design. This is an innovative way to dynamically verify the low-power intent after simulation has completed and all waveforms are available. The paper also explains how users can write their own checker... » read more

Taking Energy Into Account


Considering power throughout the SoC design flow is common practice. The same cannot be said for energy, although that is beginning to change as chips increasingly incorporate heterogeneous processing elements. Combined with this, AI/ML/DL technologies increasingly allow engineering teams to explore and optimize design data for more targeted and efficient systems. But this approach also requ... » read more
