In an increasingly connected world characterised by faster product-development cycles, companies continuously seek new ways to get to market sooner and to improve products throughout their life span - from production and manufacture to remote access in the field.To address this requirement, ARM has introduced ARM CoreSight SoC-600, a next-gen debug and trace solution. This new technology offers debug and trace over functional interfaces such as USB, PCIe or wireless, reducing the need for hardware debug probes while increasing data throughput.

Designers can now get to the root of the problem faster, reducing iterations, risk and TTM. Furthermore, it also offers OEMs and developers system visibility across a device’s lifetime, in a world where development and optimisation never stops.

ARM CoreSight SoC-600
Historically, SoC debug and trace has depended on dedicated and standardised external interfaces to provide device access to external debuggers, most notably via JTAG (IEEE-1149.1) and Serial Wire Debug. But relying on these interfaces limits the availability and accessibility of debug features to the early stages of the product lifecycle, as these connections are rarely accessible in finished products.

To remove dependencies on such standards, CoreSight SoC-600 implements the latest ARM debug and trace architecture, which provides developers with high-throughput trace and infield debug accessibility, via existing functional interfaces.

CoreSight SoC-600 offers a complete end-to-end solution for:

SoC designers - with co-developed IP and tooling for maximum productivity in the design phase.
Developers – ease of debug access thanks to readily available, validated SW drivers and debug tools.

CoreSight SoC-600 has been designed in close collaboration with the ARM IP portfolio, DS-5 Development Studio and the ARM tools ecosystem.

STMicroelectronics is among the first licensees of CoreSight SoC-600. Fabio Marchiò, Automotive & Discrete Group Vice President and Automotive Digital Division General Manager, STMicroelectronics, said: “ARM CoreSight SoC-600 enables ST to significantly increase debug and trace output bandwidth in next-gen automotive microcontrollers - especially for powertrain, advanced stability control, and ADAS, where performance needs are skyrocketing. This new trace and debug capability aims to enable our OEM partners to accelerate fault identification, reduce risk and manage costs as they develop new connected products that can be monitored throughout their lifecycle.”

Stephan Lauterbach, General Manager of Lauterbach, shared his thoughts on CoreSight SoC-600: “The combined effects of increasingly complex SoC design and rising demand for better system visibility have increased the market need for debug and trace over multi-gigabit links. With the addition of ARM CoreSight SoC-600, our debug and trace tools can now support developers in remotely debugging and analysing their firmware in the field, significantly reducing TCO and enabling new remote based services.”
