Near-Threshold Computing Gets A Boost


Near-threshold computing has long been used for power-sensitive devices, but some surprising, unrelated advances are making it much easier to deploy. While near-threshold logic has been an essential technique for applications with the lowest power consumption, it always has been difficult to use. That is changing, and while it is unlikely to become a mainstream technique, it is certainly bec... » read more

Model Variation And Its Impact On Cell Characterization


EDA (Electronic Design Automation) cell characterization tools have been used extensively to generate models for timing, power and noise at a rapidly growing number of process corners. Today, model variation has become a critical component of cell characterization. Variation can impact circuit timing due to process, voltage, and temperature changes and can lead to timing violations, resulting i... » read more

Wrestling With Variation In Advanced Node Designs


Variation is becoming a major headache at advanced nodes, and issues that used to be dealt with in the fab now must be dealt with on the design side, as well. What is fundamentally changing is that margin, which has long been used as a buffer for variation and other manufacturing process-related problems, no longer works in these leading-edge designs for a couple of reasons. First, margin im... » read more

The Week In Review: Design


Legal Synopsys filed suit against Ubiquiti Networks and its project leader for "circumventing technological measures that effectively control access to Synopsys' software." The suit, filed in U.S. District Court in San Jose, claims that Ubiquiti used counterfeit keys obtained or created with tools from hacker websites to circumvent Synopsys' License Key system. Ubiquiti, based in San Jose, d... » read more
