The article presents the concept and implementation of the emulation of the GBTX chip for data acquisition systems for NICA experiments.
The GBTX chip is widely used in high-energy experiments. However due to export restrictions, it can't be used in NICA. There is significant synergy in building readout chains for CBM and NICA experiments. To fully utilize this synergy, it is important to emulate the essential GBTX functionality in FPGA.
For that purpuse the emulator of GBTX (GBTxEMU) has been developed.
The GBTxEMU may be implemented in cheap FPGAs including Artix 7, and enables creating multichannel data acquisition chains based on the same front-end ASICs (SMX2 developed at AGH) as used in CBM. The GBTxEMU may work with the DPB boards developed for CBM, however a dedicated, price-optimized solution is planned in the future.
