In order to improve the system of full digital phase-locked loop speed, reduce the power consumption of the system, and at the same time improve the dynamic performance and steady-state performance of phase-locked system,this paper proposes a full digital phase-locked loop based on assembly line. The electronic design automation technology is used to complete the design of the system, and the designed circuit is simulated and analyzed by computer. Simulation results show that the parameters of the digital filter in the phase-locked loop can be dynamically adjusted according to the magnitude of phase error, which can not only speed up the phase-locked speed, but also enhance the stability of the system. The integrated circuit optimized by pipeline technology can reduce the system delay and reduce the total power consumption. The phase-locked loop can be embedded as a functional module into SoC（Systerm on Chip）and has a wide range of applications.
