#EDA: Cadence Design Systems Acquires Jasper Design Automation"

Cadence has lagged behind in formal verification tools, which it plans to remedy by acquiring the JasperGold Apps suite. Cadence will integrate Jasper's formal analysis toolkit into the Cadence System Development Suite to create the most comprehensive set of verification tools available today, according to the companies: R. Colin Johnson @NextGenLog

#CHIPS: "Neuromorphic Roadmap Plots Analog Path"

This roadmap cites Carver Mead's original plea to truly emulate biology with analog rather than merely simulate with digital. By emulating the continuous analog functions of the human nervous system, rather than just simulate them with step-time digital functions, you not only save power, but realize synergy among neuromorphic subsystems that cannot be simulated with digital circuitry alone: R. Colin Johnson @NextGenLog

#ENERGY: "Quantum Dots Enable Windows to Harvest Solar Energy"

The windows of the future could double as solar energy concentrators according to researchers at Los Alamos Natl. Lab which recently demonstrated a prototype: R. Colin Johnson @NextGenLog


Transparent quantum-dot-impregnated window panes luminescence under ultraviolet illumination.

Solar energy is collected by cadmium-selenium (CdSe) quantum dots which pass the energy to a cadmium-sulfur (CdS) inner cores which emits the light at a different wavelength thus concentrating the solar energy from the whole windows surface on the phovoltaic cells around the window's edge.

#CHIPS: "Archer Supercomputer Advancing State-of-the-Art"

Cray scored a major design win with its massively parallel XC30 supercomputer is the fastest in the U.K. for complex simulations--from cosmology to climate modeling to aircraft design--using Intel E5 processor chips and Aries interconnection fabric chips--R. Colin Johnson @NextGenLog


The University of Edinburgh recently installed its Archer supercomputer, which ranks as the fastest supercomputer in England.


Cray XC30 series chassis are based on blades with processor daughter cards (PDCs) and a peripheral component interconnect express (PCIe) Gen3 host interface.
