DESCRIPTION:Speakers: Adriana Milic (CERN)\n\nThe Phase-I Upgrade of the A
 TLAS Liquid Argon (LAr) Calorimeter introduceda new fully digital trigger 
 readout system\, significantly increasing thegranularity and precision of 
 information available to the Level-1 trigger.Developing and commissioning 
 such a large scale custom electronics systempresented numerous technical c
 hallenges.\nThis seminar will provide an overview of the LAr calorimeter r
 eadoutarchitecture\, with particular emphasis on the digital trigger reado
 utelectronics. After introducing the main components of the system\, I wil
 ldiscuss the experience gained during detector commissioning and Run 3oper
 ation. The talk will highlight practical lessons learned from operatingcus
 tom ASICs\, optical links\, and FPGA firmware in a demanding experimentale
 nvironment. Selected examples will illustrate how unexpected hardware andf
 irmware effects were identified\, understood\, and mitigated to achieverel
 iable detector operation.\nThe seminar aims to provide insight into bringi
 ng complex detectorelectronics from prototype to stable long-term operatio
 n\, and theengineering challenges encountered along the way.\n\nhttps://in
