Methodology to measure a front end ASIC for physic experiment

The conception of Asics is an important tool for physics experiments. Because of the small dimension, its high transistors density, its low power dissipation and its low cost, ASIC made possible the realization of new experiments in particle physics´ astrophysics and nuclear physics. The paper will deals with a methodology to ensure the convergence between physicists needs and electronics specifications, linking the ASIC conception and the way of building the experimental system. Microelectronic engineers needs to know perfectly the behavior of the front end asic and physicists wants to validate a concept of detection and the expected performances of the system. So a data acquisition system based on the final experiment needs with a small number of elements is the first step to validate an instrument, to measure the limit of the experiment (resolution), and to test the instrument from a small scale. The front end asic data acquisition system has always the same architecture for measuring the performance of the asic, for testing the slow control, the acquisition and the analysis system. Using the. Unified Modeling (UML) language, we could perfectly define the system and could write specifications according to the physicists need. So from the experiment context to the control software, a new way of building automated measurement bench has been defined. We will study this method using Asics made for ANTARES and MUST2 experiments.
