LDRA In The NewsView All
Just after the creation of the MISRA C/C++ standard by the automotive industry as a guideline for writing C code for safety-critical applications, Embedded.com in 2002 ran one of the first tutorials on the guidelines, titled “Introduction to MISRA C.”
Since then we have regularly published information on the standard and how to use it as it evolved and matured. Some of the more recent design articles, webinars, tech papers, product and news stories are included in this week’s Embedded Tech Focus newsletter on “MISRA C and safety-critical design.” The reason we have continued to focus so much on this standard over the years is that the need for such a disciplined approach is growing more necessary as embedded devices move into areas beyond automotive, military/aerospace and medical equipment to automate more and more aspects of our lives.

The LDRA Compliance Management System (LCMS), a resource for developing infrastructure that supports DO-178B/C, DO-278A, and DO-254 compliancy, has been released by LDRA. LCMS ensures certification readiness through a process that includes LDRA Certification Services (LCS) professionals support from development and production through the maintenance lifecycle.
Certification of avionics projects is a requirement. It is not an easy one to meet and the enumerable artifacts and procedures are necessary. LDRA’s Compliance Management System (LCMS) is designed to provide part of the infrastructure necessary for companies to deliver projects that are compliant with standards like:
- Aircraft & Systems Development (ARP-4754A)
- Safety Assessment (ARP-4761)
- Integrated Modular Avionics (DO-297)
- Flight Electronic Hardware (DO-254)
- Flight Software (DO-178B/C)
- Ground Systems (DO-278/A)

With recent advances in automation, software is no longer a small part of electro-mechanical systems, but instead forms the underlying technology providing functional safety for many products. By Shrikant Satyanarayan, Technical Consultant with LDRA, in India, specialising in the development, integration and certification of mission- and safety-critical systems in avionics, nuclear, industrial safety and automotive domains.
LDRA to Give Away Copies of the New MISRA C:2012 Coding Standard at UK Device Developers’ Conference
Software analysis tool company, LDRA have announced that they will be giving away a copy of the MISRA C:2012 guidelines at each of their ½ day technical workshops during the UK Device Developers’ Conference.
The Device Developers' Conference is a one-day event for developers of intelligent systems and devices, taking place in Bristol, Cambridge and Manchester during 14th – 22nd May.
Coding standards for secure embedded systems
The security of networked embedded devices is becoming a major concern. The adoption of networking in embedded systems is widespread and includes everything from domestic audio/video systems to supervisory control and data acquisition (SCADA) systems. Users are generally aware that viruses, worms and malware are attempting to infiltrate their personal computers, but many are oblivious to the fact that the devices and infrastructure they have come to rely on in their everyday lives are also coming under similar attack. Systems need to be hardened so that they are impervious to attack without relying on the user “doing the right thing” to protect them.
Sidebar: The MISRA Index
C is a very malleable language that allows developers a high degree of flexibility. The downside is that many allowed practices can result in unstructured, hard- to-maintain or faulty code that permits memory overwrites, mismatched types and so forth.
MISRA C consists of a list of rules that help developers adhere only to safe coding practices for the C language. For example, it prevents practices that are easy to get wrong or for which the resulting behaviour is undefined. In theory, checking for MISRA compliance can be done manually, but it is more practical to automate the process using a software tool.
When it comes to medical applications, high-quality software is a must. For C programmers working on safety-critical applications, however, restrictions and guidelines to ensure safe coding practices can be painful. Features of the language that are designed to make work easier or more efficient, or that provide work-arounds for obstacles, often are the very features that the guidelines disallow.
