For more than 40 years, NI has developed automated test and automated measurement systems that help engineers solve the world’s toughest challenges.  At NI, we’re revolutionizing how enterprises use test insights to drive product and business performance. Because when an organization invests in an intentional test strategy, test becomes a strategic differentiator for the business.  With our software-connected systems, the possibilities are limitless. Easily integrate your current tools and workflows and leverage your data across multiple applications to make informed decisions that drive results. Let’s work together to find creative solutions to help your organization succeed today, tomorrow, and for the next 100 years.

LDRA tool suite supports integration with LabVIEW, NI TestStand, and NI VeriStand for complete hardware / software-in-the-loop testing. The integration supports test component reuse across the full development lifecycle.

NI’s combination of software and hardware allows an extensive range of capabilities for testing target hardware, including signal generation, signal measurement, control actuation, and real time measurements.

LDRA leverages these capabilities by adding all the software analyses facilities required to achieve DO-178B certification, (up to and including Level A), and other functional safety standards. These include coding standards enforcement, structural coverage analysis (Modified Condition / Decision Coverage [MC/DC] and object code coverage), unit testing, data coupling, control coupling and requirement traceability to the software under test on the target hardware.

The NI test platform is ideal for performing system-level testing while the LDRA tool suite is designed for embedded code verification. Through the complimentary use of both toolsets test component reuse can be achieved throughout the full development cycle.

Features

Support for requirements-based testing and test component reuse in all phases of development, i.e…

• Model-in-the-loop (MIL) testing for a fully simulated system
• Rapid control prototyping when fine-tuning the control algorithm
• Hardware-in-the-loop (HIL) simulation
• Physical testing in a real-world environment

Benefits

• Reuse of test components such as data logging and stimulus profiles throughout development reduces risk and saves both time and costs
• Requirements traceability across all stages of system-level testing decreases cost of meeting safety-critical standards
• Increases quality and reduces time to market by ensuring all code has been tested (both model-generated and hand code)
• Verifies and documents adherence to required programming standards and quality metrics
