Safety in SoCs

Accelerating the Road to ISO 26262 Certification With Processor IP Today’s system-on-chip (SoC) designs are becoming more complex, increasing the pressure on verification and design teams to deliver fully functional designs. Recent studies have shown that over 50% of the development time on a complex IC is now being spent on verification, revealing the severity of the problem project teams are facing. As more SoC designs are used in electronic systems deployed in safety-critical applications, adhering to functional safety standards such as ISO 26262 has become an important consideration when defining the verification methodology. This white paper outlines the key requirements for ISO 26262 certification and demonstrates how to accelerate the development of safety-critical IP and SoCs through the use of out-of-the-box safety-ready IP with advanced verification qualification tools and methodologies.

High Field Superconducting Magnets

Applications include MRI machines, mass spectrometers, and particle accelerators. Goddard Space Flight Center, Greenbelt, Maryland A modified coil winding machine for small-diameter wire being used to enable higher packing densities for the superconducting magnets. This superconducting magnet developed at NASA Goddard Space Flight Center comprises a superconducting wire wound in adjacent turns about a mandrel to form the superconducting magnet; a thermally conductive potting material configured to fill interstices between the adjacent turns; and a voltage limiting device disposed across each end of the superconducting wire, and is configured to prevent a voltage excursion across the superconducting wire during quench of the superconducting magnet. The thermally conductive potting material and the superconducting wire provide a path for dissipation of heat.

Distributed Diagnostics and Prognostics

The distributed health management architecture is comprised of a network of smart sensor devices. Ames Research Center, Moffett Field, California NASA has developed a method that prevents total system failure during emergencies, allowing parts of the system to continue to function, and making overall system recovery faster. A heterogeneous set of system components monitored by a varied suite of sensors and a health monitoring framework has been developed with the power and flexibility to adapt to different diagnostic and prognostic needs. Current state-of-the-art monitoring and health management systems are mostly centralized in nature, where all the processing is reliant on a single processor. This requires information to be sent and processed in one location. With increases in the volume of sensor data as well as the need for associated processing, traditional centralized systems tend to be somewhat ungainly; in particular, when faced with multi-tasking of computationally heavy algorithms. The distributed architecture is more efficient, allows for considerable flexibility in number and location of sensors placed, scales up well, and is more robust to sensor or processor failure.

Lens-Coupled Dielectric Waveguides

Small, lightweight, low-power interconnect solution with improved reliability and reduced packaging complexity. NASA’s Jet Propulsion Laboratory, Pasadena, California NASA’s Jet Propulsion Laboratory has developed a low-loss dielectric waveguide that provides a simple, versatile, and flexible transmission medium. Dielectric waveguides — long, solid pieces of dielectric that confine electromagnetic waves — offer high bandwidth and low transmission loss compared to conventional metallic waveguides. Despite these advantages, practical use of these waveguides has been limited because a large fraction of signal power is lost at the state-of-the-art interconnects joining conventional metallic waveguides and dielectric waveguides. JPL’s interconnect solution uses lens coupling to reduce these losses by a factor of 10 or more, yielding a reliable, cost-effective alternative to conventional waveguides.

Sampling and Control Circuit Board for an Inertial Measurement Unit

John H. Glenn Research Center, Cleveland, Ohio Scientists at NASA’s Glenn Re - search Center have developed a circuit board that serves as a control and sampling interface to an inertial measurement unit (IMU). The circuit board provides sampling and communication abilities that allow the IMU to be sampled at precise intervals. The data is minimally processed onboard and returned to a separate processor for inclusion in an overall system. The circuit board allows the normal overhead associated with IMU data collection to be performed outside of the system processor, freeing up time to run intensive algorithms in parallel. This Glenn technology consists of the circuit schematic, board layout, and microcontroller firmware for the IMU sampling and control circuit board.
