MOTOR CONTROLFigure 4. Design with safety stepsFigure 5. Design with prequalified safety stepsand provide the right level of safe functionality.Finally, the assessor certifies the product forfunctional safety and it can be released intothe market. There are certain steps where semiconductorvendors like Altera can help withthe process and reduce the effort for the developmentof safe applications. For example, havingimmediate access to semiconductor data,IP, development flows, and design tools thatare already qualified for functional safety canprovide a significant acceleration of the overallproduct development process.Altera invested almost two years to achievequalification for their products. The requiredtest and usage data for IP and design tools anddevice reliability data are summarized and formattedin such a way that they can be presentedfor certification for functional safety. A TÜVapproveddesign methodology (V-Flow) wasdeveloped to address the specific needs ofFPGA designs. Essential diagnostic functionswere designed as FPGA IP and are provided aspart of the functional safety package. This exampleof a drive with a safe I/O uses qualifiedFPGA design tools, Quartus II software version9.0 SP2, from Altera and a suggested designmethodology for the implementation of theapplication. In addition, a dual-FPGA implementationfor the application, was used insteadof external processors and DSP. The applicationis partitioned onto several Nios II soft processorcores. The first Nios II soft processor providessupport for the communication stacks, thesecond handles the control of the system andthe third Nios II processor is integrated intothe motor control block. The motor controlalgorithm is partitioned so that its softwareportion runs on a Nios II processor and is acceleratedby hardware blocks specifically developedfor this applicator to accelerate themotor control loop. An external safety controllerprovides the redundancy required for aSIL3 application. This solution enables combiningthe safe controller with the field buscontroller in a single FPGA, and uses theAltera SOPC Builder system integration toolto integrate the Nios II soft processors withthe other IP blocks for communication, theencoder interfaces, and memory interfaces.For low-level monitoring of critical but commondiagnostic tasks in the FPGA, this exampleuses safety-qualified diagnostic IP blocks providedby Altera. These diagnostic IPs, designedto the IEC 61508 specification, perform commondiagnostic functions such as the following.1) Cyclic redundancy check (CRC) calculation- this calculation is useful in many systemsand is particularly useful for fieldbus applications.2) Derived clock checking - this corelooks at the presence and frequency of clocksin the system. 3) SEU check controller - thisblock works with the built-in soft error checkinghardware in the device to monitor changesbrought about by so-called soft errors. Sincethe implementation of these hardware IP coresis in the FPGA logic area, the system processoris relieved of these tasks.The design implementation follows the providedrecommendations. In the area of qualifiedmethods, Altera took the IEC spec and analyzedthe FPGA design methods and related clauses.From this analysis, a tool flow document wasproduced. The V-Flow and the documentationthat comes along with it maps all steps in thedesign of a safe application for Altera FPGAsto the IEC specification and its requirements.In addition, it explains which tools are usedfor the specified design steps. Specific chaptersin the IEC specification are discussed and anexplanation is provided to guide the user tofollow the right development steps for the developmentof a safe application.Altera provides a TÜV-qualified FunctionalSafety Data Package that covers qualified developmenttools, qualified IP, and qualified silicondata for devices under a specific toolflow. The documentation and data that the assessorneeds for certification are included andprovided in a format that matches preciselythe IEC 61508 specification format so theycan easily be processed by the assessor. Havingthis documentation available in the rightformat saves a significant amount of work forthe documentation of the safety project. Inthe reliability report included in the FunctionalSafety Data Package, an extensive analysis ofthe statistical information about the reliabilityof Altera FPGAs is provided. All the necessaryinformation to calculate failure-in-time (FIT)rates is part of the provided documentation,including a guideline that explains how to performthis calculation so that it can easily bepresented to the assessor for certification.

MOTOR CONTROLProduct News TI introduces InstaSPIN-FOC motor control solution<strong>Motor</strong> control system designers can now concentrate on differentiating designs rather than spendingweeks and months tuning their motor control systems. With the new InstaSPIN-FOC solution fromTexas Instruments, designers can now identify, tune and fully control (through variable speeds andloads) any type of three-phase, synchronous or asynchronous motor in five minutes or less.News ID 16923 Toshiba: ARM Cortex development board for motor controlToshiba Electronics Europe has announced a pre-configured development board for rapid implementationof motor control applications using its ARM Cortex-M3 family of microcontrollers. Developers canuse the low-cost ‘SigmaBoard’ as a starter kit, as a reference design, or as a stand-alone solution forfield-orientated control/vector control of brushless DC motors with ratings to 36V and 2A.News ID 16972 Digi-Key opens European customer support centerDigi-Key is expanding its global footprint with new sales and customer support resources coveringthe EMEA region. The company today announced its regional sales leadership team and theopening of a new European sales and support office in Munich. Offering regional support to itsEMEA customer base, Digi-Key appointed a team of experienced sales leaders, charged withsupporting an existing roster of over 41,000 EMEA customers while expanding awareness of Digi-Key to both the design engineer and the higher volume Production Business buyer. Additionalresources covering the Nordics, the Baltics, and Eastern and Southern Europe will be announcedwithin the next 90 days.News ID 17010 Telit expands Qualcomm portfolio with new LTE concept productTelit Wireless Solutions announced the expansion of its long-standing relationship with QualcommTechnologies. The complete portfolio allows Telit to offer form-factor compatible QualcommTechnologies-based solutions for CDMA, UMTS and LTE radio technologies to address the communicationsneeds of M2M and Internet of Everything application developers.News ID 16888 TI: SoftwarePac features production ready PHY and transport softwareTexas Instruments announced two new software packages for its KeyStone-based multicore Systemon-Chips.The first software offering is a new production ready small cell Physical software package,enabling developers to quickly, easily and cost effectively design highly differentiated small cell basestations. The second software offering is a transport software package for wireless and othernetwork-oriented applications.News ID 16976 Microchip: BodyCom technology uses human body as low-power communication channelMicrochip announces its BodyCom technology, which provides designers with a framework forusing the human body as a secure communication channel. Compared to existing wireless methods,BodyCom technology provides lower energy consumption, whilst further increasing security viabidirectional authentication. BodyCom technology is activated by capacitively coupling to thehuman body. The system then begins communicating bidirectionally between a centralisedcontroller and one or more wireless units. There are many applications where secure wirelesscommunication is essential, and there is no more secure channel than the human body.News ID 16930 Toshiba: new line-up of image recognition processors for automotiveToshiba Electronics Europe is offering an expanded line-up of Visconti image recognition processors withthe launch of the Visconti3 series. The first device in this new series, the TMPV7528XBG, is enhanced bythe integration of additional processor cores. Toshiba developed the Visconti series of image recognitionprocessors to advance the creation of camera-based vision systems for automotive applications.News ID 16959ore information about each news is available Mwww.Embedded-<strong>Control</strong>-Europe.com/ece_magazineYou just have to type in the “News ID”. —11 April 2013
