Development of FEB Configuration Test Board for ATLAS NSW Upgrade

A front-end board (FEB) configuration test board is developed for examining the configuration interfaces of various application-specific integrated circuits (ASICs) developed for the ATLAS New Small Wheel project. In this paper, we present the development of a FEB configuration test board, and some functions are developed in terms of configurations of the key chips on the FEB–VMM3 and trigger data serializer (TDS2) using giga-bit transceiver-slow control adapter (GBT-SCA). Additionally, the protocols provided by GBT-SCA and the front-end board ASICs are used to verify the whole data link. The board provides technical reference for prototyping the FEB key chip configuration and data readout, as well as the final system configuration.
