CoreSight SoC-400 

The Arm CoreSight SoC-400 is a comprehensive library of components for the creation of debug and trace functionality within a system.

About CoreSight SoC-400

The SoC-400 library offers configurable components to meet the exact requirements of your system, from small to multiprocessor Cortex-A class designs. With over 20 years of development behind it, CoreSight SoC-400 is the standard for Arm-based SoC designs and enjoys broad support from the tooling ecosystem.

  • Safeguard against costly delays.

  • The industry standard for debug and trace IP.

  • Comprehensive library of configurable on-chip debug and trace components.

Highlights

CoreSight SoC-400 provides configurable components for the creation of all four main aspects of debug and trace functionality:

  • Debug access.
  • Trace generation, manipulation, and output.
  • Cross triggering.
  • Time stamping.

Key features

Configurable components that are offered in CoreSight SoC-400 can broadly be classified into:

  • Debug access, to build the interface between an external debugger (using, for example, JTAG or SWD) and processors, memory systems, and other CoreSight components.
  • Trace, to generate and end trace buses, and provide the links between source and sink.
  • Cross-triggering, to allow components to control actions from and to other components.
  • Clocks, resets, and power management.
  • Time stamp, to generate and distribute time stamps across components.

Also, Arm provides separate trace components for the generation of system trace, the System Trace Macrocell (STM), and the management of intermediate and termination of trace buses, Trace Memory Controller (TMC).

  • Better trace for better software with Arm CoreSight

    This white paper explores the limitations of existing software debug and trace technologies, and explains how the Arm CoreSight System Trace Macrocell (STM) and Trace Memory Controller (TMC) enable system level visibility to more developers. This reduces latency and increases throughput, at the same time as applying existing open source trace infrastructures.

  • Low pin-count debug interfaces for multi-device systems

    This white paper examines some alternatives to JTAG as a debug interface, and concludes that a Serial Wire Debug interface can be delivered with lower pin-count and higher performance, and at the same time, maintain support for multiprocessor systems and interoperability with test.
