Use case · Existing design

Rebuild design understanding before changing legacy hardware.

Turn under-documented schematics, scattered files, and tribal knowledge into an inspectable design record for a respin, substitution, certification change, or new owner.

The problem

The person who knew why the design looks this way may be gone. Notes live in email, old repositories, issue trackers, test documents, and supplier conversations. A small change can disturb an implicit dependency no one remembered to document.

Connected workflow

Circuitly reads the available schematic and supporting record together, identifies major functional blocks and interfaces, and lets engineers interrogate the design in hardware terms. Unknowns remain visible instead of being turned into confident guesses.

01

Collect

Design files, BOMs, notes, test evidence, revisions, and available history.

02

Map

Functional blocks, interfaces, dependencies, and revision relationships.

03

Interrogate

Ask targeted questions and inspect cited design evidence.

04

Plan

Define the safe change boundary and unresolved investigation work.

Understanding package

  • Functional architecture and interface map
  • Component, rail, clock, reset, and protection context
  • Revision-sensitive dependencies and unknowns
  • Questions and risks to resolve before the change

Engineer decision

The output is a starting point for engineering investigation, not a replacement for measurement, simulation, or responsible review. Engineers decide what evidence is sufficient for the planned change.

Bring the design no one wants to touch.

We’ll map the evidence that exists and make the unknowns explicit.
