DESCRIPTION:Embedded tracing is essential for validating reliability\, opti
 mizing performance\, and debugging complex embedded software. Despite rapi
 d innovation in the RISC-V ecosystem\, open and interoperable trace soluti
 ons have remained limited. C-Trace\, developed in the context of the Europ
 ean TRISTAN project \, addresses this gap with an open-source trace encode
 r and an extensible ecosystem approach. C-Trace introduces a modular trace
 -encoder architecture designed for efficient\, continuous “live” obser
 vation. Beyond standard program-flow tracing\, it supports hardware-assist
 ed instrumentation that can automatically emit trace messages on access to
  selected control/status registers (CSRs) or on configurable watchpoints. 
 This enables trace streams that carry richer runtime context (e.g.\, progr
 am counter\, timestamps\, direct data\, and selected performance counters)
  and can support application use cases such as worst-case execution time (
 WCET) estimation\, timing optimization\, test-case prioritization\, and in
 tegration-level coverage measurement. In addition to off-chip export\, C-T
 race can forward trace-triggered events internally to an on-chip CPU\, ena
 bling watchdog\, runtime verification\, or control-flow integrity (CFI) ch
 ecking functionality. Finally\, C-Trace is provided under a dual-licensing
  model (CERN-OHL-S and a non-copyleft commercial option) to balance open c
 ollaboration with industrial IP needs.
