Implementation of a built-in self-test for nuclear power plant FPGA-based safety-critical control systems

•The built-in self-test method for nuclear power plants safety-critical FPGA-based system is proposed.•The partition strategy of built-in self-test simplifies the test structure.•The built-in self-test method improves the self-diagnosis coverage and reduces the test effort.•An FPGA-Based Reactor Trip System built-in self-test logic example is provided.
