Improving Algorithms With High-Level Synthesis


Most computer algorithms today are developed in high-level languages on general-purpose computers. But someday they may be deployed in embedded systems where the development, verification, and validation of algorithms is done in languages like python, Java, C++, or even numerical frameworks like MatLab. This is the goal of high-level synthesis (HLS), and it aims to solve a fundamental proble... » read more

Will Open-Source Processors Cause A Verification Shift?


While the promised flexibility of open source could have advantages and possibilities for processors and SoCs, where does the industry stand on verification approaches and methodologies from here? Single-source ISAs of the past relied on general industry verification technologies and methodologies, but open-source ISA-based processor users and adopters will need to review the verification flows... » read more

Managing Power Dynamically


Design teams are beginning to consider dynamic power management techniques as a way of pushing the limits on performance and low power, leveraging approaches that were sidelined in the past because they were considered too difficult to deploy. Dynamic voltage and frequency scaling (DVFS), in particular, has resurfaced as a useful approach. Originally intended to dynamically balance performan... » read more

Interdependencies Complicate IC Power Grid Design


Creating the right power grid is a growing problem in leading-edge chips. IP and SoC providers are spending a considerable amount of time defining the architecture of logic libraries in order to enable different power grids to satisfy the needs of different market segments. The end of Dennard scaling is one of the reasons for the increased focus. With the move to smaller nodes, the amount of... » read more

Betting On Hydrogen-Powered Cars


The automotive industry is taking another look at hydrogen fuel cells, but how they ultimately fare depends on a combination of consumer demand, automaker investment and infrastructure build-out. Hydrogen fuel cell technology has been steadily advancing over the past six decades since the first practical fuel cell system was demonstrated by Cambridge engineering professor Francis Bacon. The ... » read more

Thoroughly Verifying Complex SoCs


The number of things that can go wrong in complex SoCs targeted at leading-edge applications is staggering, and there is no indication that verifying these chips will function as expected is going to get any easier. Heterogeneous designs developed for leading-edge applications, such as 5G, IoT, automotive and AI, are now complex systems in their own right. But they also need to work in conju... » read more

Why Standard Memory Choices Are So Confusing


System architects increasingly are developing custom memory architectures based upon specific use cases, adding to the complexity of the design process even though the basic memory building blocks have been around for more than half a century. The number of tradeoffs has skyrocketed along with the volume of data. Memory bandwidth is now a gating factor for applications, and traditional memor... » read more

Power Complexity On The Rise


New chip architectures and custom applications are adding significant challenges to chip design and verification, and the problems are becoming much more complex as low power is added into the mix. Power always has been a consideration in design, but in the past it typically involved different power domains that were either on, off, or in some level of sleep mode. As hardware architectures s... » read more

Planning For Failures In Automotive


The automotive industry is undergoing some fundamental shifts as it backs away from the traditional siloed approach to one of graceful failure, slowing the evolution to fully autonomy and rethinking how to achieve its goals for a reasonable cost. For traditional automakers, this means borrowing some proven strategies from the electronics world rather than trying to evolve traditional automot... » read more

Service Revenue Growing With Chip Complexity


Rising complexity, new markets, and a shortage of in-house expertise are beginning to rekindle demand for services for the first time in nearly a decade. The semiconductor industry has been racing to design chips for a variety of new and existing applications, but they are facing challenges on a number of fronts: Leading-edge chips require new architectures due to a sharp reduction in s... » read more
