Press Release: Nexus Announces New 2012 “Nexus 5001 Standard Addressing Multi-core and SOC Debug Challenges” https://nexus5001.org/press-release-nexus-announces-new-2012-nexus-5001-standard-addressing-multi-core-and-soc-debug-challenges/ Mon, 25 Jun 2012 11:29:53 +0000 https://istonexus5001.wpengine.com/?p=212
2012 Nexus 5001™ Forum standard delivers superior debug solutions for faster time-to-market, higher quality to high-value markets including automotive, aerospace, telecommunications, and medical devices

PISCATAWAY, N.J., USA 25 June 2012 – The Nexus 5001™ Forum today announced the ratification of IEEE-ISTO 5001™-2012 Standard (Nexus 5001) for a Global Embedded Processor Debug Interface. Developed by the Nexus Forum, an industry group of IC companies, systems manufacturers and design automation companies, the revised standard adds support for two new interfaces – IEEE Std. 1149.7™ (JTAG) and the Nexus trace over a high-speed Xilinx® Aurora SerDes (Serializers/Deserializers) interface, delivering an array of benefits such as shortened time-to-market, for designers.

“We are very pleased to see the completion of this new standard release, which extends Nexus 5001’s value in system-on-chip (SoC) design. It provides the security and support of a proven standards-based debug framework with the flexibility to address a wide range of instrumentation solutions,” said Neal Stollon, chairman, Nexus 5001 Forum. ”The new Nexus 5001-2012 standard release adds a range of powerful features including new transactions and interfaces that address the major challenges in the debug world, better support for more complex multi-core debug environments and higher performance trace interfaces to allow higher off-chip data throughput for more comprehensive in-silicon analysis.”

Many challenges in on-chip debug are directly related to pin I/O resources. For pin-limited designs, reduced debug I/O is often important. For multi-core, SoC designs, increasing the amount of debug throughput, without increasing I/O pins is important for effective and successful analysis and calibration.

“As embedded electronic systems have become more demanding, chip designers are turning to multi-core, SoC solutions that significantly raise gate count and chip complexity. This also requires more complex verification and validation of both the microcontroller and the software running on the MCU. The high-speed Nexus trace port over Aurora allows more data to be transmitted to handle the large amounts of trace data that can be generated by multi-core SoCs,” said Randy Dees, 32-bit automotive MCU applications engineer, Freescale Semiconductor, and chairman, Hardware Technical Committee, Nexus 5001 Forum. “Nexus 5001-2012 offers a robust solution for the highly demanding data requirements for instrumentation and measurement of the customer system.

Understanding component and subsystems operations in a variety of environments over time is critically important for system qualification, calibration, upgrading, and safety-critical design in design domains such as automotive, military-aerospace, communications, and medical applications that demand high-quality debug solutions.

“GM Powertrain has utilized a Nexus-based debug interface for the past three generations of development controllers, which spans more than a decade of engine, transmission, and hybrid ECUs. Adhering to the Nexus 5001 standard is important to GM because it has provided a powerful, common interface across multiple generations of development controllers, which has enabled the ability to reuse software development tools,” said Norm D’Amico, staff engineer, Controls Engineering Tools Group, GM Powertrain, and GM representative, Nexus 5001 Forum. “Reuse of course, is a big factor in keeping costs down, and this would not be possible without following a robust standard like Nexus 5001.”

Addressing the increasing needs in trace and calibration throughput for multi-core, SoC designs, the Nexus Specification also adds support for the Nexus Protocol over Aurora. Aurora is a high-performance, serial data link layer protocol proven over a decade of successful use by industry leading companies. It is a low-latency, resource-efficient, open protocol developed by Xilinx that provides a transparent lower-level interface to the physical serial links transferring Nexus packets. Aurora enables access to the device’s transceiver capabilities and also lowers BOM cost through pin- and trace-count reduction.

“Xilinx developed Aurora to save developers the time and resources that they would otherwise need to spend if they were to develop and test their own multi-gigabit transceiver protocols. Since Aurora is a scalable, open standard that can be used in any silicon device, it has become a de-facto point-to-point, high-speed serial interconnect standard serving multiple market segments,” said Tim Vanevenhoven, director of marketing, IP Design Methodology, Xilinx. “Its use for high-performance trace operations as part of the IEEE-ISTO 5001-2012 release is yet another domain where Aurora provides best-in-class features and capabilities in performance-critical applications.”

Nexus interfaces also continue to support parallel auxiliary (AUX) buses that are widely used for trace in existing Nexus designs.

To support more effective JTAG-based operations, the Nexus standard has integrated IEEE Std. 1149.7, a next-generation extension of JTAG that defines parallel JTAG TAPS and 2-pin JTAG interfaces, as well as 1149.1 JTAG. IEEE Std. 1149.7 was added because it offers features and options to support complex digital debug issues, including power management, and multiple-core CPUs.

The Nexus 5001-2012 standard is fully available to all Nexus 5001 Forum members and their affiliates; for additional information, please visit www.nexus5001.org. For more information on Xilinx Aurora and available licensing options, please visit www.xilinx.com/aurora.

Consortium driving real-time development tool interface that is engineered for multi-core debug for reduced development cycle time

Piscataway, NJ – 6 September 2006 – Semiconductor leaders Analog Devices Inc., NEC Electronics Corporation, Tensilica, and Texas Instruments have joined the growing industry effort to address multi-processor debugging of embedded systems. To accomplish this improvement, the 22 member companies of the Nexus 5001™ Forum are driving adoption of the Nexus Standard.

The Nexus Standard (IEEE-ISTO Nexus 5001) is an embedded processor development tool interface that helps design engineers rapidly identify software- and hardware-level problems in real time. The Nexus 5001 standard is the only open debugging standard in the world and addresses the emerging multi-processor debugging problems of embedded systems with a common interface. By using a standard debug protocol available from multiple chip makers, companies can reduce time and expense when migrating between architectures. Adoption of the standard also helps reduce risk and improve overall quality and time to market.

“The ability to have real-time visibility and control of multiple embedded processor cores is only one area that the Nexus Forum has been striving for since its beginning,” said Ron Stence, long-time leader and proponent of the Nexus 5001 Forum and senior systems engineer for Freescale Semiconductor. “We are pleased to see the Forum continuing to gain momentum. Each of these new members has begun to make significant contributions to the Nexus Forum and Standard.”

“Analog Devices continuously improves the development and debug capability of it’s CrossCore Development Tools – including VisualDSP++, EZ-KIT Lite and EZ-Extenders — to support future members of its Blackfin family of processors. The Nexus 5001 Standard offers a performance and advanced feature set that enables the delivery of Trace and Real-Time data to and from a target system at a useable and sustainable rate,” said Derek Leadbetter, Director, DSP Development Tools.

Jim Trent, associate vice president and general manager of NEC Electronics America’s automotive strategic business unit stated, “NEC Electronics is pleased to become a Nexus 5001 Forum member. Our 32-bit V850™ CPU core will require more powerful and comprehensive development tools in the future. Having automotive standards helps enable more efficient support for the growing global automotive electronics market. The Nexus standardization of the tool interface will continue this momentum and accelerate the evolution and introduction of these features. We see an opportunity to expand the capability of the NEC Electronics tools for non-intrusive real-time trace and data-logging, and also enable similar enhancements for our third-party partners. The end result is better tools in the hands of our customers, which will lead to faster time to market and a reduction in their overall development investment.”

“Tensilica’s configurable processor cores are increasingly being used in larger and larger numbers per chip instead of logic blocks in complex SOC (system on chip) designs because they are faster to design, provide equivalent performance, and allow functions to be changed in firmware after the chip is made,” stated Steve Roddy, Tensilica’s vice president of marketing. “We joined the Nexus Forum standardization effort because it will enable the availability of an even broader array of world-class debugging tools needed by the growing number of multi-core SOC designers worldwide.”

Benefits of the Nexus 5001 Standard

Nexus allows for re-use of development tools and directly supports multi-core embedded processors to significantly reduce development time and resource investment for embedded systems. Establishing the Nexus Standard enables engineers and programmers to find and fix problems with their systems using emulators, debuggers, logic analyzers, hardware-in-the-loop and workstations to control embedded processors in real time.

Standardization also ensures that microprocessor systems can re-use diagnostic equipment across multiple architectures and design cycles. For example, the flexibility of a standard Nexus port allows an engineer to use the same toolset on each Nexus-enabled processor. Another major advantage is the multi-client interface capabilities of Nexus to conduct real-time multi-processor debug over a single Nexus interface.

SAN FRANCISCO, March 8, 2005 — First Silicon Solutions (FS2®) announced today at the Embedded Systems Conference that it has taken a major step forward in joining the NEXUS 5001™ FORUM to promote standardized debug interfaces for use in debugging microprocessors.

This is a growing industry effort to cut the time to market of new embedded systems. The Nexus Standard (IEEE-ISTO Nexus 5001) is a standard debug protocol available from multiple chipmakers, that allow companies to reduce development time and expense when migrating between architectures. This initiative develops a standard for embedded processor development tool interfaces designed to improve quality, mitigate risk and speed time-to-market.
Nexus 5001 Forum Standard

IEEE-ISTO 5001 is an open industry standard that provides a general-purpose interface for the software development and debug of embedded processors. As advances in semiconductor and system design continue, embedded applications are using higher-performance embedded processors. Efficient use of these embedded processors requires software and hardware development tools that can easily access critical processor functionality. Standardization on this interface benefits customers’ reuse of their Nexus 5001™ compliant development tools on compliant processor architectures.

FS2 joins Freescale Semiconductor, dSpace, Ford Motor, GM, IAR Systems, Motorola, Green Hills Software, ST Microelectronics, Metrowerks, Windriver Systems and Visteon among others, building this worldwide consortium.
