Title  Embedded Systems Development: Three Proven Practices for Speed and Agility
Summary  To address the growing demand for smarter products, many manufacturers are incorporating embedded systems into their products. While this approach offers exciting opportunities for innovation, it also adds a level of complexity to products that have zero tolerance for bus and must beat the competition to market. Companies successfully addressing these challenges are reaping the benefits with higher profitabity, an impressive achievement given the current economy.

Title  EMF’s Guide for Medical Device Company Executives
Summary  In order to assist companies to be compliant with the tenants of the new Drug and Medical Device Accountability Act, EMF has set out a series of guidelines and recommended best practices for medical device executives to consider. EMF has strived to create a strategic awareness of how currently available technology can be used to address issues pertaining to the law as well as to use the same technology to createvalue by reducing costs and enhancing design outcomes and time-to-market issues.

Title  “In my Defense let me State that the Bed was Already on Fire when I climbed into it”
Summary  The purpose of this paper is to present the medical device developer guidelines for complying with the “suggestions” of the CDRH. Technology exists today that allows a company’s current tools and processes to be retained, while presenting choices that developers can use to meet CDRH guidelines. EMF research has shown that these technologies are not only affordable, but that they can increase ROI and significantly reduce the chance of a product recall or a patient injury.

Title  UML for the C programming language.
Summary 

Unified Modeling Language (UML) has been highly successful in the modeling of software-intensive systems, including systems-oriented models and realtime and embedded designs. There are three strategies for using UML for developing C realtime and embedded applications:

  • Object-oriented modeling
  • Object-based modeling
  • Functional-based modeling

The last approach, functional-based modeling, is the focus of this paper. There are many reasons developers may want to avail themselves of the power of UML to represent the different aspects of their systems (e.g., functional, behavioral, interactive and structural) and yet eschew the use of object features completely, such as:

  • The developers may wish to represent legacy C code in models without requiring its re-architecture.
  • The developers may be more comfortable with more traditional C concepts of files, functions and variables than they are with classes, operations and attributes.
  • The system under development may be safety critical, and safety-critical designs are more difficult to certify under standards like DO-178B, Software Considerations in Airborne Systems and Equipment Certification.

Title  The Economics of Defective Software
Summary  Year-over-year, extensive EMF surveys of embedded developers clearly show that embedded designs are becoming more complex while time-to-market requirements are shrinking the time available to both complete designs on-time and meet pre-design expectations. Software testing has emerged as a critical component of the development process – particularly for complex designs when market windows of opportunity are crucial to the monetary success of the product or development.

Title  Automotive System Design and Mechatronics
Summary  Electronics and Software Engineering are quickly merging with traditional Mechanical Engineering to create a new paradigm in auto manufacturing: Mechatronics. Industry experts predict that this shift will bring about profound advances in automotive product development. Unfortunately, existing IT and process infrastructures do not provide sufficient capabilities to support the new paradigm: multiple data silos, a lack of standardized processes, and integration issues on a tool level (Mechanical, Electronic, Software) continue to pose serious obstacles to development efficiency, and remain a frequent source of delays, quality issues and cost increases. To capitalize on the many increase efficiencies that will emerge as a result of Mechatronics, OEMs and tier-one suppliers need to tightly integrate the domains of Mechanical, Electrical and Software Engineering, and collaborate more efficiently in early development phases.

Title  Smarter system development: a systems engineering trade study to support green initiatives with model-driven development.
Summary  Trade studies help us fully explore the design space to ensure that a proposed solution best meets conflicting performance and cost requirements. But many of us don't know that you can analytically and objectively conduct your trade studies well before you engineer anything. Using a model-driven approach with IBM® Rational® Rhapsody® software from IBM, you can determine which solution will best capture stakeholder requirements while also justifying your engineering decisions.

Title  A new approach to verifying and validating medical device development.
Summary 

The list of features in medical devices is rapidly rising: Even the simplest of medical devices—such as diagnostic and monitoring systems—house more and more system components, which add greater functionality to the device at a low cost. But by adding components, device software becomes complex and burdens compliance testing and premarket certification activities, such as 510(k) submissions mandated by the U.S. Food and Drug Administration (FDA).

However, you can address those issues by using a model-based verification and validation process in your medical device development. First, this process can help you better manage the complexity of the software by abstracting it as a model. Second, the process can help you verify and validate an evolving system by leveraging an executable model earlier in the development process. Lastly, the early validation and verification of a system can help you reduce the total development time and shorten the FDA submission process, a required step for bringing a device to the U.S. marketplace.

Title  The Economics of Embedded Development, Testing, Deployment and Support
Summary  In this report, EMF presents a methodology for calculating the ROI for a development based on the direct cost of development, associative costs, extrinsic costs and a process for estimating risk. This report includes a telecom infrastructure development example comparing the ROI for developments using Model Driven Development (MDD) and those not using MDD.
