Firmware development for temperature monitoring of electro-optical transceivers for the ATLAS Liquid Argon Signal Processor system — •Peter Maximilian Fischer, Markus Helbig, Rainer Hentges, and Arno Straessner — Institut für Kern- und Teilchenphysik, TU Dresden
As part of the Phase-II upgrade of the ATLAS detector, its Liquid Argon (LAr) calorimeters will be equipped with a new Signal Processor (LASP) system following the high luminosity upgrades to the LHC. The data transfer coming from the Front End Board (FEB2) to the LASP and going from the LASP to the ATLAS trigger system will be handled by electro-optical transceivers of type SAMTEC Firefly, which will have to be monitored with regards to their temperature by an FPGA. For this purpose, an I2C master has been interfaced in VHDL. A simulation in QuestaSim as well as hardware testing with a Stratix-10 FPGA on a Firefly test card and a LASP testboard were performed in order to verify the desired behaviour, with a test on an Agilex-7 based LASP testboard pending. The results and conclusions from these tests will be presented, as well as an outlook towards the implementation of a Serial Peripheral Interface (SPI) for the communication between the Agilex-7 and MAX-10 FPGAs.
