  2. 6. Mode switch for component-based multi-mode systems

    Author : Hang Yin; Hans Hansson; Tomas Bures; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; component-based; multi-mode; mode switch; Computer Science; datavetenskap;

    Abstract : Component-based software engineering is becoming a prominent solution to the development of complex embedded systems. Since it allows a system to be built by reusable and independently developed components, component-based development substantially facilitates the development of a complex embedded system and allows its complexity to be better managed.

  4. 7. Introducing Mode Switch in Component-Based Software Development

    Author : Hang Yin; Hans Hansson; Paul Pettersson; Thomas Nolte; Carlo Ghezzi; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mode switch; multi-mode; component-based; Computer Science; datavetenskap;

    Abstract : Self-adaptivity, characterized by the ability to dynamically adjust behavior at runtime, is a growing trend in the evolution of modern embedded systems. While self-adaptive systems tend to be flexible and autonomous, self-adaptivity may inevitably complicate software design, test and analysis. READ MORE

  5. 8. Switch-Level Fault Simulation Based on Local Algorithms

    Author : Peter Dahlgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; switch level; fault propagation; fault simulation; physical fault injection; short faults; stuck-at faults; fault modeling; transients; self-checking circuits; multiple dominance;

    Abstract : The presence of realistic faults in CMOS networks, such as shorts and opens, frequently gives rise to intermediate voltage values. At the switch level, these values result in undetermined logic states (X) which are likely to propagate to the outputs, causing uncertainty in the estimation of test set efficiency. READ MORE

  6. 9. Novel RF MEMS Switch and Packaging Concepts

    Author : Joachim Oberhammer; KTH; []
    Keywords : 0-level packaging; adhesive bonding; BCB; benzocyclobutene; bond strength; contact printing; film actuator; glass lid encapsulation; glass lid packaging; helium leak test; hermetic packaging; hermeticity; high isolation switch; low stress silicon nitride; low volt; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Radio-frequency microelectromechanical systems (RF~MEMS) are highly miniaturized devices intended to switch, modulate, filter or tune electrical signals from DC to microwave frequencies. The micromachining techniques used to fabricate these components are based on the standard clean-room manufacturing processes for high-volume integrated semiconductor circuits. READ MORE

  7. 10. Monocrystalline-Silicon Based RF MEMS Devices

    Author : Mikael Sterner; Joachim Oberhammer; Roberto Sorrentino; KTH; []
    Keywords : RF MEMS; radio frequency; microelectromechanical system; microsystem technology; monocrystalline silicon; switch; tuneable capacitor; high-impedace surface; phase shifter; rectangular waveguide; transmission line;

    Abstract : This thesis presents novel radio-frequency microelectromechanical (RF MEMS) devices, for microwave and millimeter wave applications, designed for process robustness and operational reliability using monocrystalline silicon as structural material. Two families of RF MEMS devices are proposed. READ MORE
