The Nexus Trace Task Group is responsible for analysis of Nexus IEEE-ISTO 5001™ standard and it's applicability for trace of RISC-V cores. The Nexus standard is well established, silicon proven and extensively documented. It's necessary to define parts of the standard that are applicable to RISC-V trace.

Github repo: https://github.com/riscv/tg-nexus-trace contains working documents and reference C code for encoder and decoder.

The following parts of Nexus specification will be addressed: * Nexus compatible trace encoding

• Trace control
• Trace configuration
• On-chip and off-chip trace routing
• Physical trace connector optionsThis group will not address the debug part of the Nexus standard.
   
  The group’s progress shall be evaluated after 4 months, at which time the charter may be revised if necessary to narrow the scope of effort.
