Step-by-step analysis walkthrough

Use when you own Linear Algebra & Tensors in an AI-VLSI review room.

1. Capture failing metric window and workload context.

2. Map decision path: data -> model -> runtime -> hardware.

3. Check data leakage, split hygiene, and feature drift.

4. Inspect model outputs and calibration behavior.

5. Profile compute, memory traffic, and scheduling overhead.

6. Classify root cause and choose owner.

7. Patch minimally and stage rollout gates.

8. Run full regression and update signoff memo.

Artifacts to collect

• tensor shape sheet, operator graph, and FLOP/memory worksheet

• dataset/model version tags

• runtime profile

• deployment KPI dashboard

• rollback plan

Reference visuals

Tensor shape and compute mapping

TENSOR MAPPING

input  [B, M, K]
weight [K, N]
output [B, M, N]

GEMM dominates MAC count and memory traffic.
Shape mismatch breaks both math and hardware mapping.

AI-VLSI deep dive

ML math is an engineering contract: shapes, uncertainty, and objective alignment must be explicit.

shape correctness     ███████████
calibration quality   █████████
metric alignment      ████████

Reports and artifacts

• tensor shape report

• calibration summary

• convergence trend

• metric correlation table

Mini case study

A shape convention mismatch silently corrupted a feature pipeline and invalidated model comparisons.

Debug branches

• Verify tensor contracts

• Check label and split integrity

• Correlate loss with deployment KPI

Senior review question

Ask: what evidence connects this ML claim to a concrete VLSI workflow decision and owner signoff?

Key takeaways

• Every AI claim should map to a measurable engineering outcome.

• Validate both model quality and hardware/runtime feasibility before adoption.

Common pitfalls

• Optimizing benchmark metrics that do not correlate with signoff goals.

• Ignoring data drift and calibration after deployment.

• Shipping ML workflows without clear rollback ownership.
