Embedded system complexity drives the need for advanced test and measurement tools

Aerospace and defense applications require greater functionality in the field, driving the need for more capable and complex embedded systems. This increased complexity, in turn, grows the need for efficient, accurate test and measurement tools and practices; yet, many are reducing or omitting test and measurement in favor of meeting tight deadlines.

"Believe it or not, the hottest new trend in embedded testing is trying NOT to test," admits Jason Schadewald, product manager for Language Products at Parasoft Corp. in Monrovia, Calif. "The pressure to deliver more capability on ever shorter timeframes generally leads to a search for shortcuts. The trend should be to move toward greater levels of automation of static analysis, flow analysis, and unit testing-increasing productivity to match growing demand.

"The importance of testing comes down to a very simple question: How urgently would you fix a related bug if it occurred in the field? The more urgently you view the potential bug, the more effort you should expend trying to test the code," Schadewald adds. "When I think about the aftermath of a misfired missile, a failed aircraft braking system, or a convoy's hacked GPS leading them into an ambush, I wonder how anyone could dare to question the value of test and measurement."

Schadewald recommends engineers and executives consider how well test and measurement systems will fit into the existing ecosystem now and in the future. "Take a forward-thinking approach to ensure your vendor's technology will stay up to date as you upgrade systems. Also communicate regularly with vendors to give them time to adapt to upcoming changes in your eco- system. We're all in this together."
