When DOB and DO are implemented efficiently, the initial increased avionics development cost is much less and will actually be cost-effective over the long-term. D and D avionics certification standards require certain tool qualification for avionics software, hardware, and testing tools.
There are two types of avionics tools which could require formal DOB or DO tool qualification: development tools and verification tools. Avionics development tool qualification is required if a tool has the potential to insert an error into the system for which other applied DOB or DO lifecycle steps would not detect. Avionics test tool qualification is required if a tool cannot insert an error but may fail to detect an error, and the other applied DO or DO lifecycle steps would not detect.
The U. Some reasons for Military DOB and DO adoption are similar to the commercial avionics certification sector: improved avionics consistency, avionics quality, measurable and verifiable avionics quality, increased avionics re-usability, and lower avionics development costs.
However, DOB and DO are more specific than A and for avionics project planning, avionics quality assurance, avionics design details, avionics robustness testing, avionics structural coverage testing, and avionics tool qualification. The military has adopted DOB and DO to obtain improvement in these areas and also produce consistency among its larger number of avionics suppliers and subcontractors.
The FAA is not actively involved in approval of military avionics. Embedded software development requires great discipline and experience. As technology advances and there is more emphasis placed on traditional PC applications, Engineers with embedded software development skills are becoming more difficult to find.
This adversely affects companies because the lack of embedded software development skills lead to cost overruns during testing, delayed time to market, and unplanned rework of products out in the field. All of this ultimately leads to low profit margins and lessens the quality of product. However, these adversities can be overcome if an embedded software developer is cognizant of the dynamics of the embedded environment and designs the embedded application to be small, efficient, and pays careful consideration to testability.
The purpose of this HighRely Reliable Whitepaper is to educate the reader in how a leading avionics services company uses DOB on a regular basis. What are the most common DB problems? With expert DOB training and set-up, this is unnecessary. The DOB integral processes are described, along with a project management timeline showing DOB software development phases and relationships. Like a chain which is only as strong as its weakest link, systems are comprised of both hardware and software and each needs its own certification guideline.
When D is implemented efficiently, the initial increased avionics development cost is much less and will actually be cost-effective over the long-term. This HighRely whitepaper describes the 13 most common DO mistakes and how you can avoid each of them. DO can easily double or triple your hardware development costs if any of these D mistakes are made. This HighRely whitepaper covers D mistakes associated with hardware requirements definition, hardware traceabilty, complex versus simple hardware certification, applying DO to components versus systems, independence, DO test coverage, DO tool qualification, and DO automated testing.
DO Verification is a key component of DO certification. However, there are two main challenges in D testing of HDL components: controllability and visibility. All DO test efforts are scoped toward getting the Device Under Test DUT to behave via a predefined set of stimulus in a predictably consistent and deterministic fashion. The purpose of this HighRely Reliable Whitepaper on DO Testing and Verification is to educate the reader in how a leading avionics services company considers DO approaches for hardware verification activities on a regular basis.
When developing real-time embedded software for safety-critical applications there must be a solid experience of the Safety Engineering processes, tools and techniques used to manage, develop, analyze and evaluate high-integrity systems across a wide spectrum of safety critical industries. The FAA and FDA have product avionics certification requirements and medical device certification requirements which are aimed at new product development. However, in many cases existing products are re-used or certified as-is.
Gap Analysis is an evaluation of your current engineering process , artifacts, and product to determine missing elements required for end-item certification. Typical missing items include low-level requirements, design documentation, independent reviews, and certain low-level tests. Gap Analysis is typically performed by trained avionics or medical device consultants including those from HighRely.
Is embedded software development such as Avionics or Medical Devices really different than developing any other quality IT product? Companies that adopt a more measured or standardized approach to establishing contingency plans and to avoid troubles will do a better job of meeting deadlines.
Details on HighRely project management methodologies are discussed in this Whitepaper. The good news for embedded software and hardware developers is that the variety and number of tools to assist their efforts are rapidly increasing.
The bad news is the qualify of these tools is often weak, integration and complexity issues are expanding, and cost-effectiveness is difficult to ascertain.
Tool integration, usability, interoperability, cost versus benefit analysis, and actual independent recommendations are provided in this HighRely Whitepaper. GPS is a worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations. GPS uses satellites as reference points to calculate positions accurate to a matter of meters. GPS receivers have been miniaturized to just a few integrated circuits.
To measure travel time, GPS needs very accurate timing. Along with distance, you need to know exactly where the satellites are in space.
You must also correct for any delays the signal experiences as it travels through the atmosphere. This paper describes how recent developments in static analysis techniques, so-called Static Verification, can be efficiently used in conjunction with functional testing techniques in order to substantially reduce debugging, code inspection, and robustness testing efforts. Static testing is a key verification technique for critical embedded systems, such as those which HighRely produces.
Included in this HighRely static analysis whitepaper are the key features static analyzers must have and analysis techniques for improving quality within embedded software.
This static-analysis whitepaper discusses how Static Verification streamlines the functional tests by simply showing errors before they cause disruptions later on while these tests are performed. Proper application of static verification, or static analysis, greatly improves quality and improves cost-effectiveness for embedded software by detecting and correcting defects at the earliest possible stage.
What are the salary and compensation levels for embedded software engineers? This whitepaper by HighRely Inc describes the pay ranges, salaries, and compensation for avionics engineers, medical device engineers, embedded software engineers, and aerospace software engineers, by experience level, skill level, job category, and geographic area. Compiled by HighRely in over one year of aerospace engineer compensation surveys and medical device software engineering consultations, this Whitepaper on embedded engineering pay rates and salaries will assist engineers and managers in determining what they should earn, or pay, embedded software engineers.
Also detailed are embedded software consulting company bill rates, compiled by a survey of consulting engineers and embedded consulting companies.
Not surprisingly, the highest engineering pay rates are found in areas which maximize coastal access, access to a cosmopolitan area, mild winters, and multiple potential employers. Also not surprisingly is the correlation of living expenses in these same areas: top-ranked engineers simply want the same amenities as everyone.
But this HighRely embedded software engineer salary and compensation survey describes the detailed pay data, along with recommendations on compensating, motivating, hiring, and retaining embedded software engineers. However, "Good" occasionally meant "Far From Great", and the revolution began. This whitepaper by HighRely Inc describes today's need to develop medical devices from finer-grained subcomponents, with open interfaces that can be composed in flexible ways, to achieve a broad range of functionalities.
In addition, these devices need to be network-centric so they can interoperate following a "plug-and-play" paradigm. And all of this advanced software must comply with the FDA's new k submission process. Given the evolving medical device landscape, what should manufacturers consider with respect to safety and the FDA?
However, if you want to achieve efficient certification of medical device software while achieving FDA k QSR compliance, you'll need to be smarter. This whitepaper provides an overview of D as well as industry best practices to avoid the common DO pitfalls. DO is relatively new and optional in most cases ; and addresses the proper incorporation of methodologies, practices, architectures, communication, partitioning, robustness, verification, and certification of modern pre-integrated avionics systems in commercial aircraft.
Increasingly considered on Military aircraft, DO has codified prior practices into an oblique but helpful treatise. A complement to DO, DO goes beyond mere software development guidelines and addresses the system and even aircraft level considerations for incorporating modularized avionics systems within an ideally seamlessly integrated holistic aircraft.
A goal rather than a reality, DO is still very helpful and a worthwhile approach and this DO whitepaper is a very useful guide. How many times has your customer demanded you meet with their top executives because one of your subcontractors did not provide what you expected? How much time and effort have you spent preparing specialized charts describing the status of your subcontractor efforts?
How often have you wished that you had received enough early warning about the status of a subcontract before a problem became critical? Despite that, however, subcontract management is frequently not done systematically. The author and other members of HighRely have worked with over one hundred companies who outsource or subcontract key engineering and manufacturing activities.
Executive management attempts to make the process more structured, but few standardized methods exist and even fewer regulations. The methods subcontract managers use to control, measure and motivate subcontractors are too often more an art than a controlled process. This whitepaper introduces key subcontracting processes to improve and control the subcontracting activity. At HighRely, we use the latest tools and techniques to perform high reliability software engineering.
We know that lives literally depend upon our safety-critical embedded software. Your life. Our life. Reliable products require reliable software engineering. And HighRely knows that high reliability requires expertly designed and developed embedded software. Program Management of complex systems, software and hardware projects? Simple or Complex Hardware? Homeland security and embedded software considerations.
