Your tape-out is in three weeks. The third-party RTL hasn't been properly reviewed.
Ark Axiom helps engineering teams reduce review scope before formal verification, signoff, DRC/ERC, and manufacturing workflows begin. We deliver fixed-scope RTL and PCB review-compression engagements with replayable evidence packets, ranked review targets, and deterministic provenance.
Used for: third-party RTL intake · AI-generated RTL review · late-stage PCB revisions · vendor IP evaluation
Runs alongside existing review workflows. No EDA replacement. No signoff changes. No workflow disruption.
Reduce review effort before verification begins.

Review Compression Packet · SHA Manifest · Review HandoffHardware teams need review compression before signoff work begins.
Third-party IP intake, open-source RTL reuse, AI-generated hardware, PCB revision churn, and supply-chain pressure are increasing the amount of hardware evidence teams must inspect before expensive verification, inspection, or manufacturing workflows.
Evidence expectations are increasing.
Security, functional-safety, customer, and regulatory review processes are asking for better hardware evidence, including EU Cyber Resilience Act reporting obligations beginning in September 2026.
Third-party hardware intake is accelerating.
Teams need a practical way to triage unfamiliar RTL or changed board artifacts before full formal campaigns, DFM/DRC/ERC, inspection, STA, or integration work.
A diff is not a review answer.
Reviewers need affected cones, changed nets, physical regions, signal impact, and replayable artifacts, not only changed lines or BOM rows.
Evidence must survive handoff.
Review artifacts need hashes, manifests, commands, and bounded claims so external evaluators can reproduce the result.
Service first: send artifacts, receive a bounded Review Compression Packet.
RTL Review Witness and PCB Revision Witness turn changed or unfamiliar hardware artifacts into bounded review targets: affected cones, suspicious signals, changed nets, board regions, warning classifications, provenance manifests, and replayable evidence packets.
This is a localized review-compression engagement, not a software deployment and not signoff. The output helps your engineers decide what deserves deeper review.
Example evidence artifact
RTL review surface
Service deliverables
RTL Review Packet
Suspicious signal ranking, cone summaries, localized SAT escalation where available, warning classifications, and replayable MD/JSON/HTML/SHA artifacts.
PCB Revision Packet
Ranked visual diff, affected nets and board regions, BOM/component deltas, SVG/HTML overlay, evidence reasons, and provenance hashes.
Command Center View
Optional evidence navigation layer for manifests, warning registers, evidence summaries, artifact hashes, review queues, and claim boundaries.
No Actionable Triage, No Fee
If the workflow does not produce at least one replayable review artifact — such as a localized suspicious cone, ranked review-priority target, affected board region, vacuity-risk classification, formal escalation candidate, or equivalence/no-material-drift evidence packet — the evaluation fee is waived.
5 Business Days
Bounded engagements are scoped up front by file count, artifact type, and review questions before the timer starts.
Not Signoff
Ark does not replace formal verification, LEC, DRC/ERC, electrical validation, inspection, certification, or production board/chip signoff.
Send a bounded RTL or PCB/BOM artifact set under NDA. Receive review targets, replayable evidence, warning status, and artifact hashes.
Request Evaluation →What you receive after a bounded review-compression engagement.
The deliverable is not an installed platform. It is a review-compression packet your engineering team can inspect, share internally, and compare against the scoped evidence.
RTL Review Witness supports RTL semantic drift detection, Yosys-assisted netlist comparison, suspicious cone isolation, localized SAT escalation where available, mutation validation, PCB/BOM revision review, visual board-region overlays, and SHA-256 manifests. Command Center organizes the Review Compression Packet when a dashboard view is useful.
NDA required. Sanitized artifacts accepted. Fixed-scope bounded evaluation engagements. Pricing depends on artifact scope, turnaround constraints, and workflow depth. Standard turnaround is 5 business days after intake. If the workflow does not produce at least one replayable review artifact, the evaluation fee is waived.
Request Evaluation →Sample artifacts show the service output before you send files.
The public packets demonstrate the shape of the deliverable: controlled mutations, public historical repair replay, localized divergence cases, PCB visual drift, manifests, and replayable artifacts. Customer-owned artifacts are evaluated only under NDA.
PicoRV32 Mutation Validation
Controlled CPU-core mutations used to test whether the workflow localizes behavior-changing RTL edits and produces bounded review evidence.
AXI Ready-Gate Bypass
Handshake and ready/valid mutation cases used to validate cone isolation, evidence summaries, and human-readable divergence notes.
Historical Repair Replay
Fifteen public Ibex, CVA6, and OpenTitan repair cases used to test whether ranked review targets overlap eventual repair regions, with random baseline and blind-structural checks.
Replayable evidence for hardware review.
Behavioral divergence needs evidence.
A changed line or BOM row is only the start. Reviewers need to know which signal, net, cone, or board region deserves deeper inspection.
Verification triage must be reconstructable.
Evidence outputs are designed for replay: the same scoped artifacts, command, constraints, and hashes should reconstruct the same triage result.
Review compression is the product.
The goal is not to replace formal verification, DRC/ERC, or inspection. It is to compress the review problem into bounded, named targets that engineers can inspect.
Every review-compression engagement produces artifacts designed to survive handoff: reviewable by another engineer, auditable by a compliance team, and reproducible against the original scoped inputs.
Cone summaries and source hashes.
Replayable. Reviewer-grade.
Localized cone scope.
Versioned. Deterministic.
Divergence reconstruction.

Engineering notes & validation briefs.
Technical notes on RTL divergence review, historical repair replay, PCB structural-drift triage, localized formal escalation, mutation validation, hardware provenance, and reproducible evidence workflows.
A Diff Is Not a Behavioral Review

These public packets are examples of what a bounded review-compression engagement returns: reviewable evidence artifacts, manifests, limitations, replay summaries, and visual review outputs. They are sample evaluation packets, not production signoff evidence.
