Sumario:The ATLAS detector at the Large Hadron Collider will undergo a major Phase-II upgrade for the High Luminosity LHC. The upgrade affects all the main ATLAS systems including the Trigger and Data Acquisition. As part of the Level-0 Trigger System, the Global Trigger uses full-granularity calorimeter cells to perform algorithms, refines the L0Calo trigger objects and applies topological requirements. The Global Trigger uses an ATCA Global Common Module as a building block of its design. The additional, standalone, Global Trigger Versatile Module has been designed according to the Global Trigger hardware specifications. The Global Trigger Versatile Module acts as an auxiliary hardware component that can be used for development, testing and operational purposes within and beyond the Global Trigger in projects requiring high bandwidth and processing capabilities. The Global Trigger Versatile Module hosts an advanced Xilinx Ultrascale+ VU13P FPGA and Finisar BOA optical modules running at data rates up to 25.8 Gb/s, as well as other hardware resources needed for the Global Trigger, located on a high-density PCB, optimized for high-speed data transmission. The Global Trigger Versatile Module successfully passed a full testing program, including verification of the main hardware functionality of the module, performance evaluation of the high-speed optical modules and the FPGA, and Global Common Module development firmware tests. Successful results demonstrating a good performance of the on-board components have been obtained.
