Advantages

The application of FPGA technology has significant advantages that can be utilized both in I&C modernization projects of existing NPPs and in I&C designs for new NPPs. These advantages are the following:
  • design, development, implementation, and operation simplicity and transparency;
  • reduction of vulnerability of the digital I&C system to cyber attacks or malicious acts due to absence of any system software or operating systems;
  • faster and more deterministic performance due to capability of executing logic functions and control algorithms in a parallel mode;
  • more reliable and error-free end-product due to reduction in the complexity of the verification and validation (V&V) and implementation processes;
  • relatively easy licensing process of FPGA-based safety systems due to the simplicity and transparency of system architecture and its design process and possibility to provide evidence of meeting licensing requirements, such as independence, separation, redundancy and diversity, in an easier and more convincing way;
  • resilience to obsolescence due to the portability of the HDL code between different versions of FPGA chips produced by the same or different manufacturers;
  • possibility of reverse engineering results implementation via emulation in FPGA of obsolete central processing unit (CPU) without modification of existing software code;
  • specific beneficial properties regarding cyber security compared to microprocessors (no viruses for FPGA).
