Accord helps EEs model non-linear, microwave, RF devices Product News 12/3/2003 Post a comment Instrument supplier Anritsu is teaming up with EDA supplier Modelithics to give developers the ability to do characterization of frequency-translating devices such as microwave mixers, up- and down-converters, and frequency multipliers. Characterization of devices working at frequencies as high as 40-GHz is possible.
'Best practices' improve hierarchical design constraints Design How-To 12/1/2003 Post a comment Setting the right physical and timing constraints is crucial for deep submicron ICs, especially with hierarchical design. In this article, Vijay Gullapalli from Synopsys Professional Services shows you "best practices" for managing constraints in hierarchical flows.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
