Formal Pipeline Checks: Step-by-Step Walkthrough

Step-by-step walkthrough

Step-by-Step Walkthrough for Formal Pipeline Checks is anchored on Proof closure on pipeline safety/liveness properties with bounded-depth convergence and vacuity review.. 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 - Formal Pipeline Checks

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
