One of the main difficulties in these solutions is how to make compatible a full custom digital design with a generic interface and the high-level control software. ALBA simplified the development process of electronic instrumentation with the use of Harmony Bus (HB)*. Based on the Self-Describing Bus, developed at CERN/GSI, it creates a bus framework where different modules share timestamped data and generate events. This solution enables the high-level control software in a Single Board Computer or PC, to easily configure the expected functionally in the FPGA and manage the real-time data acquired. This framework has been already used in the new Em# electrometer**, produced within a collaboration between ALBA and MAXIV, that is currently working in both synchrotrons. Future plans include extending the FPGA cores library, high-level functions and the development of a new auto-generation tool able to dynamically create the FPGA configuration file simplifying the development process of new functionalities.
