Hardware-Software Co-Design Reappears


The core concepts in hardware-software co-design are getting another look, nearly two decades after this approach was first introduced and failed to catch on. What's different this time around is the growing complexity and an emphasis on architectural improvements, as well as device scaling, particularly for AI/ML applications. Software is a critical component, and the more tightly integrate... » read more

Power Is Limiting Machine Learning Deployments


The total amount of power consumed for machine learning tasks is staggering. Until a few years ago we did not have computers powerful enough to run many of the algorithms, but the repurposing of the GPU gave the industry the horsepower that it needed. The problem is that the GPU is not well suited to the task, and most of the power consumed is waste. While machine learning has provided many ... » read more

How To Optimize Verification


The rate of improvement in verification tools and methodologies has been nothing short of staggering, but that has created new kinds of problems for verification teams. Over the past 20 years, verification has transformed from a single language (Verilog) and tool (simulator) to utilizing many languages (testbench languages, assertion languages, coverage languages, constraint languages), many... » read more

Breaking Down The Debug Process


Semiconductor Engineering sat down to discuss debugging complex SoCs with Randy Fish, vice president of strategic accounts and partnerships for UltraSoC; Larry Melling, product management director for Cadence; Mark Olen, senior product marketing manager for Mentor, a Siemens Business; and Dominik Strasser, vice president of engineering for OneSpin Solutions. Part one can be found here. What fol... » read more

Will In-Memory Processing Work?


The cost associated with moving data in and out of memory is becoming prohibitive, both in terms of performance and power, and it is being made worse by the data locality in algorithms, which limits the effectiveness of cache. The result is the first serious assault on the von Neumann architecture, which for a computer was simple, scalable and modular. It separated the notion of a computatio... » read more

Tackling Safety And Security


Semiconductor Engineering sat down to discuss industry attitudes towards safety and security with Dave Kelf, chief marketing officer for Breker Verification; Jacob Wiltgen, solutions architect for functional safety at Mentor, a Siemens Business; David Landoll, solutions architect for OneSpin Solutions; Dennis Ciplickas, vice president of characterization solutions at PDF Solutions; Andrew Dauma... » read more

Moderating A Panel


When I was a technologist at Mentor, I used to be asked to sit on panels. I loved to provide my opinions on just about anything. As soon as I became independent, the industry believed that I could serve it better as a moderator. That was not an easy transition to make. The first few panels that I moderated were probably not very good. I like to think that I have improved over the years, and the... » read more

Open Source Processors: Fact Or Fiction?


Open source processors are rapidly gaining mindshare, fueled in part by early successes of RISC-V, but that interest frequently is accompanied by misinformation based on wishful thinking and a lack of understanding about what exactly open source entails. Nearly every recent conference has some mention of RISC-V in particular, and open source processors in general, whether that includes keyno... » read more
