MANHASSET, NY -- The Nexus 5001 Forum has added two new interfaces and ratified IEEE-ISTO 5001-2012 Standard as a global embedded processor debug interface.
Nexus 5001 added support for IEEE Std. 1149.7 (JTAG) and the Nexus trace over a high-speed Xilinx Aurora SerDes (Serializers/Deserializers) interface.
The Nexus Forum is an industry group of IC companies, systems manufacturers and design automation companies.
”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,” said Neal Stollon, chairman, Nexus 5001 Forum, in a statement.
“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.
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, according to the 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," said Norm D'Amico, staff engineer, Controls Engineering Tools Group, GM Powertrain, and GM representative, Nexus 5001 Forum.
The Nexus Protocol over Aurora is a serial data link layer protocol developed by Xilinx that provides a transparent lower-level interface to the physical serial links transferring Nexus packets.
“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 at Xilinx.
The Nexus 5001-2012 standard is available to all Nexus 5001 Forum members.
