A new methodology for designing and development of complex systems for high energy physics

Makowski D.

International Journal of Microelectronics and Computer Science

2016

Vol. 7, nr 4

123--132

The paper describes a new methodology that allows to design scalable complex control and data acquisition systems taking into consideration the additional, non-functional requirements of High-Energy Physics (HEP). Electronic systems applied in HEP often operate in difficult conditions. Access to such devices is difficult or even impossible. The HEP systems require high availability, serviceability and upgradeability. The operating conditions of these systems are even more difficult than for telecommunication devices. Therefore, a different methodology should be applied than for classical telecommunication systems, when designing electronics used in high-energy physics applications. Electronic systems also need a suitable hardware platform that not only assures high availability, simplifies maintenance and servicing but also allows to use mixed analogue-digital signals. The author made an attempt to develop a new methodology suitable for designing of complex data acquisition and control systems of HEP. The Low Level RF (LLRF) system of European Free Electron Laser (EXFEL) and Image Acquisition System (IAS) prototype developed for International Thermonuclear Experimental Reactor (ITER) tokamak are presented as examples of complex electronic systems that were designed according to the proposed methodology.

As a result of a growing interest in the xTCA systems by research centers conducting High Energy Physics (HEP) experiments, the PICMG xTCA for Physics Coordinating Committee is developing a new, attractive standards. They are specifically dedicated to control and data acquisition systems of HEP applications. These new specifications define a number of extensions to the Advanced Telecommunications Computing Architecture (ATCA) and Micro Telecommunications Computing Architecture ( μ TCA) standards. The MicroTCA for Physics specification, named MTCA.4, defines some new solutions in order to simplify an application of μ TCA specification in HEP facilities. The most important of them is μ RTM module which can be connected to the Advanced Mezzanine Card (AMC) and provides more usable area and additional I/O connectors at the rear of the shelf. The MTCA.4 also introduces additional channels dedicated for timing and synchronization signals that are available on backplane. Due to the fact that xTCA for Physics is a new specification which has not been officially published, both the AMC and μ RTM modules and the software for the MMC with possibility of μ RTM handling are not yet available. For this reason the preparation of firmware for the Module Management Controller (MMC) for AMC modules compatible with MicroTCA for Physics specification is required. This paper presents a structure of the MMC for the μ TC (MicroTCA-based Controller) board. It also describes the microcontroller software which fulfills the role of the MMC.

Automated generation of FRU devices inventory records for xTCA devices

The Advanced Telecommunications Computing Architecture (ATCA) and Micro Telecommunications Computing Architecture (μTCA) standards, intended for high-performance applications, offer an array of features that are compelling from the industry use perspective, like high reliability (99,999%) or hot-swap support. The standards incorporate the Intelligent Platform Management Interface (IPMI) for the purpose o advanced diagnostics and operation control. This standard imposes support for non-volatile Field Replaceable Unit (FRU) information for specific components of an ATCA/μTCA-based system, which would typically include description of a given component. The Electronic Keying (EK) mechanism is capable of using this information for ensuring more reliable cooperation of the components. The FRU Information for the ATCA/μTCA implementation elements may be of sophisticated structure. This paper focuses on a software tool facilitating the process of assembling this information, the goal of which is to make it more effective and less error-prone.
