LDRA Integrates the Tool Suite with LabVIEW Virtual Instruments

Published:2012/1/3 4:41:00 Author:Amy From:SeekIC

LDRA has added its tool suite to National Instruments LabVIEW Virtual Instruments. The LDRA-NI solution provides hardware-in-the-loop (HIL) simulation. It is a technique used to develop and test the complex real-time embedded systems commonly found in military and aerospace designs. Thanks to LDRA’s expertise in safety-critical systems, NI’s hardware testing capabilities are fully satisfied to the software competencies necessary to achieve DO-178 certification up to and including Level A. because of joint NI hardware testing capabilities with LDRA’s software testing expertise, experts can imitate how a complete hardware-software system will react to real-life test conditions. For conjunction with NI’s hardware application, LabVIEW Virtual Instruments produce a simulated system with an extensive range of capabilities for testing target hardware that includes signal generation, signal measurement, control actuation and real-time measurements. When these systems are exposed to an extensive range of test data, they simulate the responses of a system to the data, enabling developers to quickly identify the likely response of a target system under test.

The integration with the LDRA tool suite ensures full software analysis applied to the systems on the simulated target hardware. LDRA also can test software systems up to DO-178 Level A. It includes code standards enforcement, structural coverage analysis including modified condition/decision (MC/DC), object code coverage, unit testing, data and control coupling, and requirements traceability. The integration allows LDRA’s automated unit testing tool TBrun to generate inputs to and read outputs from LabVIEW Virtual Instruments, resulting in bidirectional control and data collection.
