CoreSight Debug and Trace

Gives System Visibility to All Developers

With the increasing complexity of modern SoCs, access to the most comprehensive suite of debug and trace solutions is critical to reduce time-to-market and validation effort.

The ARM® CoreSight™ family of IP products offer solutions to address the needs of silicon partners and developers alike, from SoC bring up to software debug and system optimization and finally post-mortem debug.

Original Equipment Manufacturers (OEMs) are expecting silicon providers to provide a reliable and complete hardware and software system ready for applications development, and this is a key differentiator. A well thought-out debug and trace solution helps partners address these challenges.

CoreSight offerings include components for the implementation solutions for debug access, instruction tracing, cross-triggering and time-stamping.
