An Entangled Heterarchy


For decades, a form of structural hierarchy has been the principal means of handling complexity in chip design. It's not always perfect, and there is no ideal way in which to divide and conquer because that would need to focus on the analysis being performed. In fact, most systems can be viewed from a variety of different hierarchies, equally correct, and together forming a heterarchy. The e... » read more

Designing Chips For Outer Space


If designing chips in cars sounds difficult, try designing them for space. There are huge temperature swings, and more radioactive particles than on Earth, which can cause single-event upsets, transients, functional interrupts, and latch-ups. A destructive latch-up can ruin a device, and in space that could transform an expensive piece of hardware into space junk. Ian Land, senior director for ... » read more

Startup Funding: October 2023


Investors are betting heavily on data center technology, with October funding going to companies developing data processing units (DPUs) to accelerate a variety of tasks, a near-memory distributed dataflow architecture for AI, and liquid cooling technology. Much of this is linked to the build-out of the edge, closer to the source of the data than the cloud but not as compute-intensive. Other ... » read more

Blog Review: Nov. 8


Siemens' Todd Westerhoff takes a look at the three stages of power integrity analysis for PCBs, challenges to board-level signal integrity, and best practices for getting the most accurate estimate of design performance. Synopsys' William Ruby provides a brief overview of the evolution of low-power design techniques and finds opportunities to reduce power and to make chip designs more energy... » read more

New Insights Into IC Process Defectivity


Finding critical defects in manufacturing is becoming more difficult due to tighter design margins, new processes, and shorter process windows. Process marginality and parametric outliers used to be problematic at each new node, but now they are persistent problems at several nodes and in advanced packaging, where there may be a mix of different technologies. In addition, there are more proc... » read more

DRAM Test And Inspection Just Gets Tougher


DRAM manufacturers continue to demand cost-effective solutions for screening and process improvement amid growing concerns over defects and process variability, but meeting that demand is becoming much more difficult with the rollout of faster interfaces and multi-chip packages. DRAM plays a key role in a wide variety of electronic devices, from phones and PCs to ECUs in cars and servers ins... » read more

Rebalancing Test And Yield In IC Manufacturing


Balancing yield and test is essential to semiconductor manufacturing, but it's becoming harder to determine how much weight to give one versus the other as chips become more specialized for different applications. Yield focuses on maximizing the number of functional chips from a production batch, while test aims to ensure that each chip meets rigorous quality and performance standards. And w... » read more

Connection Perfection


Whether you are a DFT engineer or a SoC designer, connectivity validation will no doubt be a top priority when taking steps to guarantee the functionality and reliability of your device. SoC designs continue to grow in both size and complexity to meet the ever-growing performance and power demands associated with modern technology. To keep up with this fast-paced evolution, the corresponding D... » read more

Automated Constraint Management For Faster Designer Productivity


Constraints management helps shorten the designer’s manual constraints transformation effort across the design cycle with automated constraints management flows. The management of constraints refers to tasks that are not associated with verifying the correctness of constraints, nor associated with the generation of constraints, but with the transformation of constraints from one form to anoth... » read more

Chip Industry Week In Review


By Susan Rambo, Gregory Haley, Jesse Allen, and Liz Allan President Biden issued an executive order on the “Safe, Secure, and Trustworthy Development and Use of Artificial Intelligence.” It says entities need to report large-scale computing clusters and the total computing power available, including “any model that was trained using a quantity of computing power greater than 1,026 inte... » read more
