Product intent to buildable machine

Specification to Microarchitecture

Follow one realistic DMA subsystem from an ambiguous product request to measurable requirements, executable interface contracts, a block architecture, and an evidence-ready handoff.

Learn to expose missing assumptions early, budget throughput and buffering with units, choose structures deliberately, and preserve bidirectional traceability through RTL and verification.

Part 1 · Requirements and scenarios

Write measurable requirements and executable scenarios

Replace ambiguous product language with observable contracts, operating envelopes, timelines, failure cases, and invariants that a verification plan can prove.

Start Part 1

Part 2 · Partition and contracts

Assign state ownership and boundary contracts

Partition decisions and mutable state into precise owners, then define acceptance, lifetime, ordering, backpressure, error, reset, and cancellation at every interface.

Open Part 2

Part 3 · Budgets and handoff

Close quantitative budgets and hand off the evidence

Connect bandwidth, latency, buffering, outstanding work, implementation cost, and PPA, then deliver the decisions and proof obligations downstream.

One requirement · six owned contracts

Turn a throughput promise into a block-level proof plan.

Select a blueprint node to inspect its role, contract, failure mode, and evidence.
