Embedded software: White paper shows how to use testing to improve software quality

A white paper entitled Why Use Software Verification? is available for download from the Control Engineering Resource Center. The paper discusses the rigorous standards employed for mission-critical software in the aerospace and automotive industries and shows how the standards can be employed in general embedded-system software development.

Oak Brook, IL — “Software development often proves far more expensive than expected,” says Paul Humphreys, a software engineer with LDRA Ltd. in his paper entitled Why Use Software Verification? “Bugs discovered late in the development cycle send costs soaring and risk the integrity and safety of a system,” he says. The paper, available for download from the Control Engineering Resource Center, goes on to discuss the rigorous standards employed for mission-critical software in the aerospace and automotive industries, and shows how these can be employed in general embedded-system software development.
Developers of non-safety-critical systems can benefit from the type of rigorous standards employed within the aerospace and automotive industries. In addition to producing reliable software, costs can be contained and requirements met more easily by adhering to a software quality process. The earlier a defect is discovered, the less impact it has on development time and cost. There is much to gain by ensuring requirements are captured in full, are well understood, and are specified completely and unambiguously. Bugs discovered late in the development cycle send costs soaring and risk the integrity and safety of a system, especially if the software has been deployed.
“Obviously, careful planning, organization, and a team with the correct skills all help. However, it is verification and validation that identify when and how the development process drifted from what was intended or required by the user,” says Humphreys. “Validation focuses on producing the right software system while verification ensures the software is built the right way. Both should be evident at each stage of development.”

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
