A collaborative HDL management tool for ATLAS L1Calo upgrades

Coordinating firmware development among many international collaborators is becoming a very widespread problem in particle physics. Guaranteeing firmware synthesis with P&R reproducibility and assuring traceability of binary files is paramount. Our HDL managing tool tackles these issues by exploiting advanced Git features and being deeply integrated with HDL IDE, with particular attention to Intellectual Properties handling. In LHC Run3, the ATLAS L1Calo Trigger system will be upgraded with new feature extraction and readout modules. Our tool, handling firmware development for these modules, was developed in Python and integrated with CERN Gitlab (using Web-Hooks, Gitlab API) and Xilinx Vivado.
