Here is the list of the Top 10 How-To Design Articles posted on Military Aerospace Designline in the first half of 2012, as determined by your page views.
1. Optimizing FPGAs for power: A full-frontal attackBy Chandra Sekar Balakrishnan, solutions development engineer, Xilinx, Inc.
This piece is a hands-on how to optimize FPGA designs for low power operation. This is a universal topic but, of course, it is really important for wireless and mobile military and aerospace applications that run on battery power. Such applications go from planes, to drones to frontline soldier communication equipment.
2. A design to generate UAV electrical power in flightBy Guy Wagner, Electronic Cooling Solutions, and Travis Mikjaniec, Mentor Graphics
A team of engineers at Electronic Cooling Solutions worked with John Langley and engineers at Ambient Micro to build an exhaust-heat thermoelectric generator that can be incorporated into a UAV design to harvest and convert this waste energy into electrical power in flight.
3. Drones: A hazard to your health?By Robert Dewar, co-founder, president and CEO of AdaCore and Emeritus Professor of Computer Science at New York University
Mid-February, President Obama signed a new FAA re-authorization bill that allows the use of drones into commercial U.S. skies. Here, Robert Dewar, AdaCore's CEO, explains that it's time to take security seriously and to let people know that the technology to do this currently exists.
4. FPGA testing for DO-254 complianceBy Louie De Luna, Aldec DO-254 program manager
This article describes key challenges that can be encountered when verifying FPGA pin-level requirements during board-level testing under DO-254 guidelines.
5. Designed for spaceBy Gabor Marosy, Budapest University of Technology
MASAT-1 Ė Mastering the challenges of building Hungary's first micro-satellite with Altium Designer
6. DO-178C takes safety-critical software development to the next levelBy Tim King, DDC-I and Bill StClair, LDRA
DO-178C will bring safety-critical software development into the modern era, adding support for advanced techniques such as UML and mathematical modeling, object-oriented programming and formal methods, which will enable designers to conceptualize, architect and encapsulate their design at a higher level.
7. Verify automatically generated flight code for DO-178By Tom Erkkinen, MathWorks
This article describes how to measure code efficiency and perform code verification activities using MATLAB and Simulink product family Release 2011b, featuring the Embedded Coder for flight code generation.
8. Disciplining a precision clock to GPSBy Steve Fossi, Symmetricom
Precision timing is an essential component of modern communications and navigation systems. While the signals from GPS satellites are sufficient for many applications, often these systems require a local precision timing reference.
9. Developing secure code using SPARK (Part 1)By Benjamin M. Brosgol, AdaCore
In part one of this two-part article, we will discuss the general issues surrounding software security and summarize potential approaches based on language subsetting. In part two
, we will explain how the SPARK technology specifically addresses these issues.
10. High-integrity object-oriented programming with Ada - Part 1By Benjamin M. Brosgol, Senior Software Engineer, AdaCore
Part 1 of this three-part article reviews the basics of object-oriented programming and summarizes the challenges it presents for high-integrity programming. Note that Part 2
provides a primer on the Ada programming language, and Part 3
details the tools Ada offers to help developers meet the OOP challenges.----------------------
