White Paper: PCI Express(r) Carriers and OpenVPX

Curtiss-Wright Staff Curtiss-Wright Controls Defense Solutions

Mezzanine carrier cards have been used in system designs for many years, and will continue to play an integral part, especially as the performance of processor cards continue to increase in the future. This white paper will discuss the many uses of carrier cards designed specifically for VPX and OpenVPX systems. First, let's define what we mean by a mezzanine carrier card. In some system designer's vernacular, a mezzanine carrier card can be defined as any card that can host a mezzanine. Although one can take this simple approach, we will be bit more restrictive in our definition. In this white paper, we will refer to a mezzanine carrier card as a card that can host one or more mezzanines but does not provide any processing function. The processing function or control of the mezzanine is provided by another card in the system. Stated another way, the mezzanine carrier is used to host a mezzanine which is then controlled and used by a "processor" card in the system. Hence, we could refer to the mezzanine carrier as being "dumb".

White Paper: SCADE System, a comprehensive toolset for smooth transition from Model-Based System Engineering to certified embedded control and display software

Thierry Le Sergent Esterel Technologies Alain Le Guennec Esterel Technologies

The International Council on Systems Engineering (INCOSE) defines system engineering as an interdisciplinary approach and means to enable the realization of successful systems. It focuses on defining customer needs and required functionality early in the development cycle, documenting requirements, and then proceeding with design synthesis and system validation. The main challenges of system engineering are related to providing non-ambiguous and coherent specification, making all relevant information readily available to all stakeholders, establishing traceability between all activities, and providing the appropriate level of verification and validation. Tools supporting these activities in an efficient way are not yet widely deployed in the industry.

White Paper: VPX for High-Performance Avionic Computers

Creative Electronic Systems

Traditional high-performance computing platforms are limited by the connection bandwidth and latency between the multiple computing elements needed to achieve the performance targets. For the embedded market, the difficulty is compounded by the demanding environmental requirements. The VPX standard resolves this limitation with a large number of high-throughput point-to-point connections between the processing elements in a rugged mechanical structure.

White Paper: Testing & Debugging Avionics Systems that Use ARINC 429 or MIL-STD-1553 Data Busses

LeCroy Corporation

The data busses in aircraft and spacecraft require very high quality in transmission and reception since proper communication of commands and data are crucial to operation. The ARINC 429 standard used predominately in commercial aircraft and the MIL-STD-1553 bus used in military avionics and space vehicles (military and commercial) have some common characteristics as well as important differences. This paper will give useful examples of how to view, test and troubleshoot these busses using digital oscilloscopes.

White Paper: Enabling 10Gbit-Ethernet in Miniature I/O Connectors for Aerospace and Defense Applications

Earle Olson TE Connectivity

The CeeLok FAS-T connector, a new high-speed circular I/O, combines the ruggedness of a MIL-C-38999-style design with an insert specifically configured for 10 Gbit-Ethernet transmission. Additionally, it is a small-form-factor connector system that is field repairable and supports data rate requirements for current and next-generation electronic systems in Aerospace and Defense applications.

White Paper: Enabling High-Speed Data Rates in Connectors for Aerospace and Defense Applications

Matthew McAlonis TE Connectivity

A new high-speed connector system for aerospace and defense applications builds on industry-proven technology to achieve new levels of ruggedness. By combining the designs of cutting-edge high-speed connectors with proven MIL - SPEC contacts, the new Fortis Zd connector meets the demands of emerging military applications by enabling data rates of 10 Gb/s+ while performing in military-level vibration and shock conditions.
