Abstract
Silicon Tracking System (STS), Muon Chamber (MUCH) and Transition Radiation Detector (TRD) subdetectors in the Compressed Baryonic Matter (CBM) detector system at Facility for Antiproton and Ion Research (FAIR) use the same innovative protocol ensuring reliable synchronization of the communication link between the controller and the front-end ASIC, transmission of time-deterministic commands to the ASIC and efficient readout of data. The paper describes the FPGA-based tester platform which can be used both for the verification of the protocol implementation in a front-end ASIC at the design stage, and for testing of the produced ASICs. Due to its modularity, the platform can be easily adapted for different integrated circuits and readout systems.
