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.
Collect
Design files, BOMs, notes, test evidence, revisions, and available history.
Map
Functional blocks, interfaces, dependencies, and revision relationships.
Interrogate
Ask targeted questions and inspect cited design evidence.
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.
