Apart from the SoC use case for the ATLAS muon TGC front-end electronics, which we (the UTokyo team) presented in the previous meetings, we are also working on ATLAS L0 Muon Endcap Sector Logic. This time, we would like to introduce our SoC-related study on the endcap SL. We use Enclustra commercial mezzanine card (with XCZU5EV device) on the SL for control and testing purposes. In the initial commissioning, we have implemented a control interface of the SL board (to be interfaced to the ATLAS Run Control application in the future) and also a single-board DAQ system for the testing purpose by interfacing the SoC device to the main FPGA (XCVU13P) on the SL. We want to share our experience of the implementation, integration, and commissioning from these studies.
