NuDE 2.0: A model-based software development environment for the PLC & FPGA based digital systems in nuclear power plants

NuDE 2.0 (Nuclear Development Environment) is a model-based software development environment for safety-critical digital systems in nuclear power plants. It makes possible to develop PLC-based systems as well as FPGA-based systems simultaneously. The NuDE starts from a formal requirement specification specialized for the nuclear domain, and synthesizes C and Verilog codes for PLC and FPGA, respectively, through a series of model transformation. It also provides various methods for formal verification and safety analysis with support of automatic CASE tools. We expect that the NuDE can be adopted as an effective method of bridging the gap between the PLC and FPGA-based developments as well as a means of gaining diversity.
