This process may involve multiple tools from the same or different vendors, making it complex and challenging. Additionally, scientific institutions such as DESY require long-term maintenance and reproducibility for designs that may involve multiple developers, further complicating the process. To address these challenges, we have developed an open-source FPGA firmware framework (FWK) at DESY that streamlines development, facilitates collaboration, and reduces complexity. The FWK achieves this by providing an abstraction layer, a defined structure, and guidelines to create big FPGA designs with ease. FWK also generates documentation and address maps necessary for high-level software frameworks like ChimeraTK. This paper presents an overview and the idea of the FWK.
