Trace and Debug Modules: Step-by-Step Walkthrough

Step-by-step walkthrough

Step-by-Step Walkthrough 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.

1. Define failing workload and acceptance threshold.

2. Capture reproducible metadata and evidence snapshot.

3. Classify dominant mechanism path.

4. Propose minimal reversible change.

5. Validate cross-workload and corner behavior.

6. Document owner and rollout decision.

RISC-V PIPELINE DIAGRAM - Trace and Debug Modules

PC -> IF -> ID -> EX -> MEM -> WB
      |     |      |      |      |
  i-cache decode  ALU/BR  LSU    regfile write
              \   |
               +-> branch resolve + redirect

Hot paths:
  - branch + load-use dependencies in ID/EX
  - memory latency stretching MEM stage
  - writeback arbitration for integer/vector units

Focus: keep control hazards predictable
