RISC-V’s Software Portability Challenge


Experts At The Table: RISC-V provides a platform for customization, but verifying those changes remains challenging. Semiconductor Engineering discussed the issue with John Min, vice president of customer service at Arteris; Zdeněk Přikryl, CTO of Codasip; Neil Hand, director of marketing at Siemens EDA (at the time of this discussion); Frank Schirrmeister, executive director for strategi... » read more

Verification Tools Straining To Keep Up


Verification engineers are the unsung heroes of the semiconductor industry, but they are at a breaking point and desperately in need of modern tools and flows to deal with the rapidly increasing pressures. Verification is no longer just about ensuring that functionality is faithfully represented in an implementation. That alone is an insolvable task, but verification has taken on many new re... » read more

Blog Review: June 19


Siemens' John McMillan and Todd Burkholder suggest using an automatic formal-based approach to verifying chiplet package connections early in the design process. Cadence's Veena Parthan explores the intricacies of wind tunnel testing in automotive design and how the collaborative relationship between computational fluid dynamics (CFD) and wind tunnels has resulted in accelerated and more nua... » read more

RISC-V Heralds New Era Of Cooperation


RISC-V is paving the way for open source to become accepted within the hardware community, creating a level of industry collaboration never seen in the past, while revitalizing the connection between academia and industry. The big question is whether this arrangement is just a placeholder while the industry re-learns how to develop processors, or whether this processor architecture is someth... » read more

Trouble Ahead For IC Verification


Verification complexity is roughly the square of design complexity, but until recently verification success rates have remained fairly consistent. That's beginning to change. There are troubling signs that verification is collapsing under the load. The first-time success rate fell (see figure 1) in the last survey conducted by Wilson Research, on behalf of Siemens EDA, in 2022. A new survey ... » read more

IC Security Issues Grow, Solutions Lag


Experts at the Table: Semiconductor Engineering sat down to talk about the growing chip security threat and what's being done to mitigate it, with Mike Borza, Synopsys scientist; John Hallman, product manager for trust and security at Siemens EDA; Pete Hardee, group director for product management at Cadence; Paul Karazuba, vice president of marketing at Expedera; and Dave Kelf, CEO of Breker V... » read more

What Does 2023 Have In Store For Chip Design?


Predictions seem to be easier to make during times of stability, but they are no more correct than at any other period. During more turbulent times, fewer people are courageous enough to allow their opinions to be heard. And yet it is often those views that are more well thought through, and even if they turn out not to be true, they often contain some very enlightening ideas. 2022 saw some ... » read more

Selecting The Right RISC-V Core


With an increasing number of companies interested in devices based on the RISC-V ISA, and a growing number of cores, accelerators, and infrastructure components being made available, either commercially or in open-source form, end users face an increasingly difficult challenge of ensuring they make the best choices. Each user likely will have a set of needs and concerns that almost equals th... » read more

AI-Powered Verification


With functional verification consuming more time and effort than design, the chip industry is looking at every possible way to make the verification process more effective and more efficient. Artificial intelligence (AI) and machine learning (ML) are being tested to see how big an impact they can have. While there is progress, it still appears to be just touching the periphery of the problem... » read more

The High But Often Unnecessary Cost Of Coherence


Cache coherency, a common technique for improving performance in chips, is becoming less useful as general-purpose processors are supplemented with, and sometimes supplanted by, highly specialized accelerators and other processing elements. While cache coherency won't disappear anytime soon, it is increasingly being viewed as a luxury necessary to preserve a long-standing programming paradig... » read more
