  • Effort Estimation for Embedded Software Development
  • Software cost estimation has been a subject of academic and practitioners research since the start of software engineering in the 1950s. Sixty years later, most companies in the domain of business applications continue to rely on expert judgment to estimate software development costs. This article provides an introduction to the subject of software estimation and how to apply some tips to the development of embedded applications.

  • Demystifying Software Coupling in Embedded Systems
  • This paper clarifies common misunderstandings about the concept of software coupling for embedded software development. It explains the concepts of software coupling, and the importance of taking software coupling into consideration during the software life cycle. It provides guidelines on how to improve the project’s standards and coding practices to reduce the impact that software coupling has on the project’s complexity and delivery time.

  • Introduction to DO-178B
  • This paper provides a brief introduction to DO-178B. It discusses software airworthiness and how DO-178B was created as a tool to comply with certification requirements, including an overview of the software criticality levels and the number of objectives to be satisfied for each of them. Finally, it provides an overview of the development and integral processes along with their objectives and respective software life-cycle data.

  • 7 Keys to Successful DO-178C Audits
  • The FAA has established a software audit process that ensures compliance to the DO-178C objectives and other applicable software policy, guidance, and issue papers. The intent of this article is to assist you in being successful when the FAA’s Designated Engineering Representative (DER) or delegate performs an audit of your software project.

  • Economic Recession – Short Term Pain, But Long Term Opportunity
  • This is the second recession of the decade and both of them have hit the avionics industry hard.  The good news is that the lessons learned last time can help the avionics industry and other industries avoid repeating the same mistakes.  But are we doomed to repeat them anyway?

  • Using Verification Metrics to estimate DO-178B/C Projects
  • How high is your confidence level in estimating DO-178C verification projects?  If the answer isn’t high, then maybe you need to take a close look at which metrics you are basing your estimates off of and how you are capturing them.  This article offers a number of tips that can help establish a methodology to get your confidence up.

  • Introduction to DO-254: Design Assurance Guidance for Airborne Electronic Hardware
  • Still haven’t made the time to read the RTCA/DO-254 hardware quality assurance guidelines that have been used for programmable logic in airborne systems for years now?  Well here’s a quick overview that might be a little more palatable.

  • Assuring Certifiability of Outsourced Software – a DER’s Perspective
  • Any company that has developed airborne software that must comply with RTCA/DO-178B, realizes that this is not an inexpensive or low risk endeavor. Many companies reduce their cost and risk by outsourcing, but what are the concerns your DER will have with this decision. Randall Fulton, a veteran DO-178B and DO-254 DER offers some insight.

  • DO-178B Tool Qualificaton
  • Using of tools in a DO-178B project not only has a direct impact on productivity and bottom line but also can reduce the probability of errors on manual activities. Structural Coverage Analysis and Code Review tools are often provided with an accompanying qualification package. But, what do you do when you find a tool you want to use and a tool qualification package is not available, or when you want to develop your own tools. Former Avionyx Engineering Manager gives us a down-to-earth white paper that guides us through the Tool Qualification process following the guidelines in DO-178B and Order 8110.49.

  • Costa Rica: The near-shore alternative for Embedded Software Engineering
  • India has nearly cornered the market on off-shore software development, but now there´s an alternative that´s in the central time zone and is a 3-5 hour flight from at least 10 US cities and offers highly trained software engineering talent that competes with any Indian provider, particularly for DO-178B or any embedded software development. To find out why Intel, HP, Avionyx and other US companies have banked on Costa Rica.
