SIMULATION / SA-MEM-HBM-002

HBM/base-die partition map
HBM Base Die

A browser CSV lab for memory-system partitioning: compare workload traffic, HBM stack class, base-die controller/PHY/RAS placement, interposer budget, thermal class, capacity, bandwidth, energy, and yield risk before calling an HBM plan feasible.

EXPLORE

Start with the observable.

Use this page when the simulation is the primary artifact. The linked lesson explains the concept; the linked lab keeps the visual replay surface available.

guided exploration
  • Compare host-controller baseline, controller-in-base-die, controller/PHY/RAS-in-base, and custom die-to-die wrapper partitions.
  • Filter workload, stack height class, thermal class, interposer budget, and yield posture before reading the decision gate.
  • Watch bandwidth, capacity, thermal headroom, yield risk, integration risk, and base-die area proxy move together.
  • Use operator, engineer, integration, and yield views to keep one score from becoming an overclaim.

BROWSER INTERACTIVE LAB

Filter the saved CSV. Inspect matching replay rows.

No server solver is running here. The browser filters a precomputed table and redraws the plot locally.

Each metric is normalized independently for shape inspection. Vertical positions do not compare magnitude across metrics.

RUN CARD

Conditions before conclusions.

The browser filters saved CSV rows. It does not run a live memory-system simulator, package solver, controller verification flow, SPICE deck, or vendor stack model.

METHODS

How the number was made.

Methods are written for citation discipline: the extraction rule matters as much as the plotted value.

method

Generate a Cartesian synthetic sweep over workload, partition, stack, thermal, interposer, and yield factors.

Keep this method attached when reusing the figure or metric.

method

Normalize public HBM/base-die vocabulary into proxy scores for bandwidth, capacity, energy, thermal, yield, and integration review.

Keep this method attached when reusing the figure or metric.

method

Apply decision gates that prioritize thermal, yield, and integration review before any partition candidate label.

Keep this method attached when reusing the figure or metric.

method

Store the CSV, typed JSON, model card, and source boundary under the public data folder and experiment folder.

Keep this method attached when reusing the figure or metric.

LIMITS

What this page does not claim.

The MVP is useful because the limits are visible. These statements prevent a teaching simulation from being cited as silicon evidence.

non-claim

No vendor HBM stack, base-die floorplan, TSV map, interposer database, PHY macro, controller IP, JEDEC timing table, package CFD result, or measured product data is included.

Carry this boundary into any derivative note, paper draft, or slide.

non-claim

No live server solver, architecture simulator, controller test, package thermal solver, upload, account, payment, comment, newsletter signup, job/event submission, or qualification workflow is active.

Carry this boundary into any derivative note, paper draft, or slide.

non-claim

No product release readiness, timing signoff, bandwidth certification, capacity guarantee, thermal qualification, yield prediction, procurement recommendation, or fab/APC control claim is made.

Carry this boundary into any derivative note, paper draft, or slide.

non-claim

Rows are normalized synthetic teaching proxies and require rights-cleared replacement evidence before stronger engineering reuse.

Carry this boundary into any derivative note, paper draft, or slide.

EVIDENCE

Trace the claim back to artifacts.

The evidence route remains the catalog-level browser; this page is the simulation-level reading card.
