Then, the strategies and scheme of application specific integrated circuit (ASIC) realization are determined according to the precision, area and power, and the ASIC realization are completed. Finally, through simulation, universal verification methodology (UVM) verification and logic synthesis, results show that the module can achieve the desired goal and detect 25 downlink control information (DCI). Compared with the similar module, the area of the ASIC design in this thesis is smaller about 8.33%; the power consumption is lower about 7.72%.
