Aging In Advanced Nodes


Semiconductor Engineering sat down to discuss design reliability and circuit aging with João Geada, chief technologist for the semiconductor business unit at ANSYS; Hany Elhak, product management director, simulation and characterization in the custom IC and PCB group at Cadence; Christoph Sohrmann, advanced physical verification at Fraunhofer EAS; Magdy Abadir, vice president of marketing at ... » read more

Designers Face Growing Problems With On-Chip Power Distribution


The technology evolution in semiconductor manufacturing has led to chips with ever-higher power densities, which is leading to serious problems with on-chip power distribution. Specifically, the problems surrounding voltage drop—or IR drop (from V=IxR)—have become so acute that we have seen multiple companies starting to get back dead silicon from the fab. For example, a recent 7nm chip ... » read more

Enabling Cheaper Design


While the EDA industry tends to focus on cutting edge designs, where design costs are a minor portion of the total cost of product, the electronics industry has a very long tail. The further along the tail you go, the more significant design costs become as a percent of total cost. Many of those designs are traditionally built using standard parts, such as microcontrollers, but as additional... » read more

Process Corner Explosion


The number of corners that need to be checked is exploding at 7nm and below, fueled by everything from temperature and voltage to changes in metal. Lowering risk and increasing predictability of an SoC at those nodes starts with understanding what will happen when a design is manufactured on a particular foundry process, captured in process corners. This is basically a way of modeling what i... » read more

Minimizing Chip Aging Effects


Aging kills semiconductors, and it is a growing problem for an increasing number of semiconductor applications—especially as they migrate to more advanced nodes. Additional analysis and prevention methods are becoming necessary for safety critical applications. While some aspects of aging can be mitigated up front, others are tied to the operation of the device. What can an engineering tea... » read more

Accelerating SoC Time To Market With Cloud-Based Verification


This paper discusses the growing use of cloud and hybrid cloud environments among semiconductor design and verification teams. The schedule and efficiency benefits seen by verification teams using cloud are specifically highlighted, due to the considerable compute requirements associated with verification of advanced node SoCs, and the significant impact verification has on the overall SoC proj... » read more

Blog Review: Sept. 12


Cadence's Paul McLellan checks out the impact the Meltdown, Spectre, and Foreshadow vulnerabilities will have on future processor design with an overview of speculative execution and why it's important to current architectures. Mentor's Matthew Ballance suggests some ways to find existing information and descriptions that can be used to jump-start the creation of portable stimulus models. ... » read more

Week In Review: Design, Low Power


Cadence teamed up with nine PCB manufacturing partners on an ecosystem to provide easier access to partners' technology files to improve PCB manufacturability. The program, DesignTrue DFM, allows for automated import of a manufacturer's latest DFM rules as well as rule checking in real time as part of the PCB layout process. The nine initial PCB manufactures supporting the program are: Bay Area... » read more

Cracking The Auto IC Market


The market for automotive electronics is booming, and it has set off a global scramble among established chipmakers and startups. What's becoming clear, though, is that not everyone understands just how different automotive is from the mobile market. Mobile is still the highest-volume market for semiconductors, but the growth has flattened. In contrast, the value of the automotive electronic... » read more

Finding Security Holes In Hardware


At least three major security holes in processors were identified by Google's Project Zero over the past year, with more expected to roll out in coming months. Now the question is what to do about them. Since the beginning of the PC era, two requirements for hardware were backward compatibility and improvements in performance with each new version of processors. No one wants to replace their... » read more
