Trace and Debug Modules: Design Space

Design Space for Trace and Debug Modules.

Design space

Design Space for Trace and Debug Modules is anchored on Average time-to-root-cause for failing regressions using trace capture and debug trigger workflows.. Convert observations into mechanism-backed decisions with explicit ownership.

  • Trade latency and throughput against power and area.

  • Prefer architecture options with clear software contract impact.

  • Quantify extension-profile cost before enabling by default.

  • Keep bring-up and validation ownership explicit.
