About LDRA

LDRA is an ISO 9000/9001:2008 certified company, dedicated to providing high quality products and services to its customers developing mission-, safety-, and security-critical applications.


Ultra developed a midlife upgrade of a pre-existing, uncertified, avionics system and faced significant challenges due to the introduction of requirements for DO-178B Level B safety certification coupled with a migration to a commercial off-the-shelf (COTS) hardware platform.  The LDRA tool suite was utilised to overcome the identified challenges to develop a safety-certifiable platform running on VxWorks.

LDRArules, is a product which provides companies with the ability to easily see how the source code performs in the areas of:

  • Industry-specific and user-defined standards
  • Security vulnerabilities
  • Fault detection
  • Adherence to programming standards

LDRArules incorporates next-generation reporting capabilities to show code quality, fault detection and avoidance measures. Users have the ability to quickly and easily view results in call graphs, flow graphs and code review reports in an easy-to-read, intuitive format. LDRArules enhances collaboration and communication across all members of the development team through an easy-to-use graphical user interface and sophisticated reporting mechanisms.

These measures combine to quickly analyse and report valuable information on the project code base to testers, developers, and project managers. With this information development teams can quickly identify and repair any coding flaws, speed up the development cycle, and reduce overall development cost.
