PROGRAMING TOOLs & DESIGN KITS Key trends for development systems in 2014 By Nick Flaherty Functional safety, some parts of the Internet of Things and increasing consolidation are all going to be key trends for development systems in 2014, according to Stefan Skarin, CEO of Swedish ARM specialist IAR Systems. However the rise of Intel into the Internet of Things and more x86-based embedded devices isn’t an issue. “It’s going to be a good year for the hardware side,” he said. “Trace functionality is increasing and more and more companies are moving to trace. With the Cortex A and R you need a trace solution and it comes for free so people assume its automatically in there for other devices. “ This is a key part of the increasing move to designs where safety is important, from automotive to pharmaceutical equipment. “Functional safety is a very interesting segment and I think we see more real projects where companies invest in functional safety,” he said. A key example of this is Wittenstein High Integrity Systems in Bristol, which extended its SafeRTOS Real Time Operating System to support IAR Systems’ safety certified development tool-chain IAR Embedded Workbench for ARM. SafeRTOS is an IEC61508 SIL 3 safety certified Real Time Operating System that delivers high performance and dependability to safety critical applications, whilst utilising minimal resources. Used throughout the Industrial, Medical, Nuclear and Transportation sectors, SafeRTOS is supplied with a Design Assurance Pack supporting certification to a wide range of international design standards. IAR Embedded Workbench for ARM includes pre-certified tools that simplify the certification process of the end product as they remove the need to generate a time consuming and problematic ‘proof of use’ claim against the tool. Instead the developer only needs to show compliance with the constraints defined within the all-important Safety Manual. The initial SafeRTOS port supporting IAR Embedded Workbench has been developed for use with the Hercules Safety Controller from Texas Instruments. “We see an increasing number of our customers replacing components they have traditionally used in their safety critical products in preference for modular, safety certified alternatives,” said Andrew Longhurst, Engineering Manager for Wittenstein. “Our customers are seeking the benefits of using pre-certified components including outstanding levels of determinism and robustness, but also a smoother and quicker route to achieving their own product certification.” “Companies developing safety-related applications can benefit greatly from the combined offerings of WHIS and IAR Systems,” said Anders Holmberg, Product Manager for Functional Safety, IAR Systems. “Using pre-certified, highly integrated tools will simplify their certification process, which will enable them to save time as well as money. Thanks to IAR Systems’ extensive functional safety support and update agreement, they can also be sure their development tools investment is protected throughout the product life cycle.” Wittenstein provides board support packages for use with SafeRTOS which include USB, data storage and networking components, as well as bespoke drivers. The Renesas functional software package for its 32-bit RX631 and RX63N microcontroller is also coming to the market through IAR this month (February 2014), providing a self-test diagnostic software library and a complete safety manual. The new solution provides diagnostic software for the RX CPU core and its internal memory, and a detailed safety manual to significantly reduce development time for designs that need to conform to stringent safety directives for industrial equipment, such as safety controllers, programmable logic controllers, industrial motor drives and safety sensors. “Compliance with safety directives such as IEC61508 is a necessary yet complex process for developers designing industrial or safety systems,” said Ritesh Tyagi, Senior Director, Marketing, Renesas Electronics America, Inc. “Renesas’ new RX Functional Safety solution simplifies this process by providing pre-certified diagnostic software and a comprehensive IAR Systems’ CEO Stefan Skarin: “There are a lot of x86 and MIPS legacy designs out there but if they move, they move into the ARM market” 40 Electronic Engineering Times Europe February 2014 www.electronics-eetimes.com
