Variation’s Long, Twisty Tail


Variation is becoming a bigger challenge at each new node, but not just for obvious reasons and not always from the usual sources. Nevertheless, dealing with these issues takes additional time and resources, and it can affect the performance and reliability of those chips throughout their lifetimes. At a high level, variation historically was viewed as a mismatch between what design teams in... » read more

In-Design Power Rail Analysis


Tech Talk: Kenneth Chang, senior staff product marketing manager at Synopsys, talks about what can go wrong with power at advanced nodes and why in-design power rail analysis works best early in the flow in helping to reduce overall margin. https://youtu.be/0oiWQPS1-Xk » read more

Emulation-Driven Implementation


Tech Talk: Haroon Choudry, director of Prime Power at Synopsys, talks about how to shorten time to market and increase confidence in advanced-node designs, while also reducing the amount of guard-banding and improving design freedom. https://youtu.be/xT3CIqjnaBk » read more

Tech Talk: eFPGA Timing


Flex Logix's Chen Wang talks about timing for an embedded FPGA and how that differs from ASIC timing. https://youtu.be/n88D1N4IEbs » read more

More Nodes, New Problems


The rollout of leading-edge process nodes is accelerating rather than slowing down, defying predictions that device scaling would begin to subside due to rising costs and the increased difficulty of developing chips at those nodes. Costs are indeed rising. So are the number of design rules, which reflect skyrocketing complexity stemming from multiple patterning, more devices on a chip, and m... » read more

Mashup At 7nm


The merger of two standards organizations typically falls well below the radar of most engineers, but folding the ESD Alliance (formerly known as the EDA Consortium) into SEMI is a different kind of deal. Ever since the introduction of finFETs and multiple patterning, EDA tools have become an integral part of the development of new manufacturing processes. Without those tools, there is no po... » read more

Design Rule Complexity Rising


Variation, edge placement error, and a variety of other issues at new process geometries are forcing chipmakers and EDA vendors to confront a growing volume of increasingly complex, and sometimes interconnected design rules to ensure chips are manufacturable. The number of rules has increased to the point where it's impossible to manually keep track of all of them, and that has led to new pr... » read more

The Next 5 Years Of Chip Technology


Semiconductor Engineering sat down to discuss the future of scaling, the impact of variation, and the introduction of new materials and technologies, with Rick Gottscho, CTO of Lam Research; Mark Dougherty, vice president of advanced module engineering at GlobalFoundries; David Shortt, technical fellow at KLA-Tencor; Gary Zhang, vice president of computational litho products at ASML; and Shay... » read more

The Great Machine Learning Race


Processor makers, tools vendors, and packaging houses are racing to position themselves for a role in machine learning, despite the fact that no one is quite sure which architecture is best for this technology or what ultimately will be successful. Rather than dampen investments, the uncertainty is fueling a frenzy. Money is pouring in from all sides. According to a new Moor Insights report,... » read more

More Degrees Of Freedom


Ever since the publication of Gordon Moore's famous observation in 1965, the semiconductor industry has been laser-focused on shrinking devices to their practical, and more recently, impractical limit. Increasing transistor density has encountered a number of problems along the way, but it also has enabled us to put computers—which once filled specially built rooms—onto the desktop firs... » read more
