  • Testing mixed signal ASICs through the use of supply current monitoring
    Proceedings ETC 93 Third European Test Conference, 1
    Co-Authors: K.r. Eckersall, P.l. Wrighton, I.m. Bell, B.r. Bannister, G.e. Taylor

    Abstract:

    The authors investigate testing of mixed signal integrated circuits. Several approaches are proposed, most requiring careful partitioning of the Analogue and digital Sections. However, the use of supply current monitoring is applicable to both digital and Analogue Sections. Digital testing has been widely investigated, concentrating on quiescent I/sub ddq/ testing. Using pseudo-random binary test signals with supply current testing, high fault coverage of both catastrophic FET faults and gate oxide shorts in the Analogue Section is shown to be obtainable. Use of on-chip supply sensors has also been investigated. >

  • IOLTW – Robust data compression for Analogue test outputs
    Proceedings of the Eighth IEEE International On-Line Testing Workshop (IOLTW 2002), 1
    Co-Authors: A. Rankov, G.e. Taylor, J. Webster

    Abstract:

    Ohletz [1991] described a mixed signal circuit architecture which can be reconfigured to allow built-in-self-test of both Analogue and digital parts. In testing the Analogue Section an on board test signal can be generated from digital components, the Analogue test output fed through an A-D converter and the resulting digital bit stream used as the input to a digital signature analyser. Clearly such a test strategy has a number of advantages, but particular issues arise in using signature analysis in this way due to the tolerance bands associated with Analogue signals. Such tolerances complicate the process of A-D conversion and lead to possible differences in the bit stream between two good devices with the danger of classifying good devices as faulty. The paper describes and evaluates a method for overcoming this problem by illustrating it with a number of circuits.

  • Application of Computers in Experiments Design, Building and Evaluation of a New Generation of Multichannel Analyzers Implemented in Xilinx ZYNQ-7020
    Instruments and Experimental Techniques, 2019
    Co-Authors: V. Esmaeili Sani, M. Mohamadian, I. Alizadeh, H. Afarideh

    Abstract:

    Recently, SoCs (System on a Chip) are the serious competitors and even more efficient systems than CPUs and other data processing systems based on FPGA and computer. Also, the Multi-Channel Analyzer (MCA) is one of the main components of the nuclear electronics system that determines many of the radiation measurement parameters. A prototype of the proposed new generation of MCA systems, based on SoCs, is presented which is very small, compact, and at the same time, has the full functionality of a data acquisition board. It also has many features for analyzing output data and making changes to the overall system structure through software. The designed board uses ZYNQ to provide substrate and main infrastructure to add more peripherals for any specific application. The proposed system is in fact a multi-purpose system that can simultaneously provide the functionalities of an oscilloscope, computer-independent spectrum demonstration, and even any desired application for inaccessible radiation fields thanks to its low cost, lightness and compact size. In addition, the designed Analogue Section in this system, besides the digital Section, facilitates making the system more compact and flexible in order to fully customize, match and remove some conversional Analogue parts.
