Do You Know For Sure Your RISC-V RTL Doesn’t Contain Any Surprises?


Given the relative novelty and complexity of RISC-V RTL designs, whether you are buying a commercially supported core or downloading a popular open-source offering, there is the small but non-zero risk of unwanted surprises escaping undetected into your end-product. In order of high-to-low probability, consider: The presence of a weird-yet-entirely-possible corner-case bug Bugs “insid... » read more

Growth Spurred By Negatives


The success and health of the semiconductor industry is driven by the insatiable appetite for increasingly complex devices that impact every aspect of our lives. The number of design starts for the chips used in those devices drives the EDA industry. But at no point in history have there been as many market segments driving innovation as there are today. Moreover, there is no indication this... » read more

Greener Design Verification


Chip designs are optimized for lower cost, better performance, or lower power. The same cannot be said about verification, where today very little effort is spent on reducing execution cost, run time, or power consumption. Admittedly, one is a per unit cost while the other is a development cost, but could the industry be doing more to make development greener? It can take days for regression... » read more

A Minimal RISC-V


Microcontrollers exist in almost everything, but can RISC-V satisfy the needs of this market? Is it small enough to replace 8-bit processors? What might help people migrate to a more modern processor architecture? RISC-V defines a 32-bit processor instruction set architecture (ISA) that is open source and free to be implemented in any number of ways. It is touted for being a very small and e... » read more

Is Programmable Overhead Worth The Cost?


Programmability has fueled the growth of most semiconductor products, but how much does it actually cost? And is that cost worth it? The answer is more complicated than a simple efficiency formula. It can vary by application, by maturity of technology in a particular market, and in the context of much larger systems. What's considered important for one design may be very different for anothe... » read more

Industry Transforming In Ways Previously Unimaginable


Early in the year, everyone expected that the availability of COVID vaccines would signal the start of a return to normal, but that has certainly not been the case. Now the industry is taking a longer-term view about how to transform business, what is necessary for people to maintain their mental health, and how to create robust hybrid work environments for the future that do not discard the po... » 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

The Past Predicting The Future


It is often said that you cannot predict the future by looking at the past, but that isn't always correct. There are many clues provided by digging into change. Those changes are a prelude to what may happen in the future. One way we can do that here at Semiconductor Engineering is by looking at changes in reading habits. What types of articles are attracting the most attention? This is a sure ... » read more

Growth And Enthusiasm At The RISC-V Summit 2021


We weren’t sure what to expect from our first major attendance at a #RISCVSummit. Although we were a founding member of RISC-V – as we’ve been saying quite a lot recently – we have been hiding our light under a bushel. We’ve certainly been busy though – enabling over 2 billion RISC-V cores with our RISC-V processor IP and Studio tools while helping customers use architecture lice... » read more

Improving Energy And Power Efficiency In The Data Center


Energy costs in data centers are soaring as the amount of data being generated explodes, and it's being made worse by an imbalance between increasingly dense processing elements that are producing more heat and uneven server utilization, which requires more machines to be powered up and cooled. The challenge is to maximize utilization without sacrificing performance, and in the past that has... » read more
