Optimized DO-178C Strategies for gathering, analyzing and testing of Data Coupling and Control Coupling Analysis in Critical DO-178C projects.

Exactly what to do to satisfy the Data Coupling and Control Coupling objective in DO-178 has often been misunderstood. Part of this comes from the definition documented in the DO-178B which did not truly reflect the concern that the objective addressed and the objective to be satisfied purely by analysis without any testing. Changes in DO-178C to reflect the concern more accurately has sometimes confused the issue for many developers. As a result, the topic has been the focus of a CAST paper and several DO-178 FAQ’s. This whitepaper aims to explain exactly what Data Coupling and Control Coupling are and identify what the Certification concern is that is behind the objective. In clarifying what real issue is, this whitepaper will identify where in the development lifecycle the issue should be considered, what activities should be performed in order to mitigate the concern and therefore achieve the objective. This whitepaper will also give clear recommendations for activities and approaches that can optimise your approach to satisfy the objective that will give you a pass results independent of Certification Authorities.

Top DO-178C Optimization Tactics for Planning Aspects

This DO-178C white paper, is based on ConsuNova’s recurrent Avionics Gap Analyses performed worldwide over the years. Some experts say that plans should detail every aspect of software process. However, based on ConsuNova involvements in many projects, there is a fine line between “detailed planning” and “good planning”. The discussions in this 16-page white paper focuses on important Challenges, Recommendations and “takeaways” related to the Planning aspects. DO-178C Optimization Tactics shows the reader the specific examples on how to improve DO-178C planning with adequate content and strategy to achieve successful compliance in optimized manner while governing a practical process for the DO-178C life-cycle during the project.

Practical Rules for DO-178C Requirements Capture

This whitepaper discusses why ARP 4754A, DO-178C and DO-254 place emphasis on writing correct, complete and testable requirements. ConsuNova provides this paper to introduce a framework of rules for capturing functional requirements which should minimize program risk and maintain schedules.

DO-178C and its Impact 

This paper identifies the major differences between DO-178B and DO-178C, along with a description of the impact of DO-178C on the industry. This paper also examines the relationship between DO-178C and the supplements, DO-330, DO-331, DO-332, and DO-333.

Understanding DO-330 and Overview of Software Tool Qualification

For the construction and safety certification of airborne systems software, the software tools used to build this software generally needs to be qualified. This qualification provides evidence that the software too is suitable for use, when building such safety-related airborne software. This paper identifies the major activities outlined in DO-330, along with a description of the impact it has on the industry at large. It also examines the relationship between DO-178C and DO-330.

DO-178B Description & Case Study

The purpose of this ConsuNova white paper is to educate the reader in how ConsuNova implements DO-178B on a regular basis. Note that DO-178B was also applied to the development of avionics hardware until the FAA officially recognized the DO-254 standard for developing hardware. Please refer to the ConsuNova’s DO-254 white papers for more information.

Military Avionics Certification via DO-178B & DO-254

For decades, Military organizations have developed hardware and software using a variety of specialized, defense-oriented standards including 2167A, 498, and 882. As Military organizations, they were highly motivated to use hardware and software standards which differed from the commercial sector since it was perceived that military applications were “different”. Militaries utmost concern was primarily “Mission”. Today, however, there is an accelerating momentum toward Military/Commercial avionics convergence: adopting DO-178B and DO-254 worldwide. Today, fighter jets (Joint Strike Fighter, T-50, etc.), Cargo planes (C-130, C-17, A400M, etc.) and UAV/UAS’s are requiring compliance to DO-178 and increasingly, DO-254.

DO-178B Tool Qualification

Tool qualification is required whenever the design assurance process(es) described in RTCA/DO-178B or RTCA/DO-254 are eliminated, reduced, or automated by the use of the tool unless the output of the tool is verified. Verification of the tool’s output must be accomplished through the verification process as defined by RTCA/DO-178B section 6.

Traceability per DO-178 & DO-254

Safety-critical systems including DO-178C and DO-254 require traceability. But what is DO-178 and DO-254 Traceability? This whitepaper describes all aspects of DO178 and DO254 traceability including top-to-bottom and bottom-to-top closed loop traceability for DO-178C and DO-254. Popular traceability tools for DO-178C & DO-254 are discussed as well as traceability trade-offs for D0-178B and D0-254. Requirements traceability, design traceability, and test traceability within DO-254 and DO-178 are all described along with means to maximize effectiveness for DO-178C & DO254 traceability.

DO-178B Overview & Process Flow

The DO-178B guidelines describe objectives for software life-cycle processes, activities and design considerations for achieving those objectives, and proving that the objectives have been satisfied. The majority of DO-178B is dedicated to describing a sequential waterfall development methodology for new, custom-built avionics software. This approach is a requirements-based development and verification methodology that includes a number of alternative methods for satisfying the objectives.

DO-178B Costs versus Benefits

DO-178B is the benefactor, or bane, of avionics projects the world over. But is DO-178B really expensive? Does it add value? Will it improve safety and reliability? Does it have benefits? What are the true costs versus benefits? These important questions are answered in this ConsuNova White Paper.
