Introduction to ReqGen

ReqGen is a specialized artificial intelligence tool designed to generate High-Level Requirements (HLR) and Low-Level Requirements (LLR) following DO-178C standards, which are critical for software development in safety-critical environments such as aerospace. This tool automates the translation of code into a structured set of requirements that align with the rigorous standards of DO-178C, ensuring software safety and compliance. For example, when provided with source code for an avionic control system, ReqGen can dissect the code to outline broad system functionalities and objectives (HLR) as well as detailed algorithms, data structures, and specific functionalities (LLR). This clear separation between overarching goals and detailed implementation aspects makes ReqGen invaluable for software developers in the aerospace industry, streamlining the certification process and enhancing the efficiency of developing safety-critical software.

Main Functions of ReqGen

  • Generating High-Level Requirements (HLR)

    Example Example

    For a flight navigation system's code, ReqGen would generate HLRs such as 'System shall provide real-time navigation guidance to the pilot.'

    Example Scenario

    This function is particularly useful during the initial phases of software development, ensuring that the software's broad objectives align with the intended operational capabilities and safety standards.

  • Generating Low-Level Requirements (LLR)

    Example Example

    From the same flight navigation system's code, ReqGen might generate LLRs like 'Software shall calculate the aircraft's position using GPS data every 2 seconds.'

    Example Scenario

    This function aids in the detailed development phase, specifying the exact requirements that software developers need to implement, ensuring precision and adherence to safety standards.

  • Ensuring DO-178C Compliance

    Example Example

    ReqGen automatically checks the generated requirements against DO-178C standards for compliance, identifying any gaps or inconsistencies.

    Example Scenario

    This is crucial for aerospace software developers needing to ensure their software meets rigorous safety and certification standards, facilitating a smoother certification process.
