The invention belongs to the technical field of control system DCS simulators, and in particular relates to an FPGA-based security level DCS simulator. In simulation of an FPGA algorithm actuator according to the technical scheme, a data processing and algorithm block scheduling operation mechanism of the simulator is consistent with the execution of the actual FPGA controller. What you see is what you get. Running logic on an FPGA can be debugged and verified through the simulator, and the fault diagnosis of each device module in each DCS control system by the FPGA controller is simulated. The FPGA-based security level DCS simulator can simulate a fault status debugging fault security function; a maintenance network protocol based on a data link layer is simulated, and an FPGA simulator can be used seamlessly instead of FPGA hardware to perform download and debugging operation through an engineer station. 本发明属于控制系统DCS仿真器技术领域，具体涉及种基于FPGA的安全级DCS仿真器。本发明技术方案对FPGA算法执行器的仿真，其数据处理、算法块的调度的运行机制与实际FPGA控制器执行致。所见即所得，可通过仿
