Requirement in. Verified decision out. Nothing assumed quietly.
Five steps, one model. Each step writes into the same dependency graph, which is what makes the last step — change tracking — possible at all.
Capture the requirement as structured engineering data
The requirement arrives as prose, a spreadsheet, or a conversation. Suyantra turns it into typed constraints — input range, rail currents, ambient limits, mechanical envelope — and records where each value came from. Anything it had to derive is marked as inferred; anything it had to assume is marked as assumed and surfaced immediately.
Build the design model, including what depends on what
Architecture, power tree and component positions become nodes in a graph. Crucially, the edges are recorded too: this capacitor exists because of that rail, which exists because of that input range. The dependency graph is not a visualisation added at the end — it is the data structure the rest of the product runs on.
Reason over evidence, not over vibes
When Suyantra proposes an architecture or a candidate part, it retrieves the datasheet parameters, constraints and design rules that bear on the decision, and cites them. The reasoning layer is allowed to propose and explain. It is not allowed to conclude on its own — that is the next step's job.
The operating point, from the model.
A part proposed for the position.
Datasheet parameters, cited.
Physics and derating policy.
Pass, fail or blocked.
Verify deterministically, and refuse to guess
Checks run as rules against the model: ratings, margins, budgets, derating. A rule either has its inputs or it does not. If it does not, the result is blocked, the missing input is named, and every check waiting behind it is queued rather than run on a substituted value. This is the difference between a copilot an engineer can sign off behind and one they have to double-check.
Track the change, and everything it invalidates
When a decision moves, Suyantra walks the graph and produces the impact set: what must be re-verified, what needs a margin review, and what the recorded dependencies show is untouched. Verification results that no longer hold are cleared rather than left to look current. The change, its reasoning and its impact stay with the design.
Suyantra does not sign off. You do.
The product is designed so that the engineer keeps every decision that matters — and gets the reasoning, the evidence and the open questions needed to make it well.
Selection stays with the engineer
Candidate architectures and parts are proposed with their trade-offs. The choice, and the reason for it, is recorded against your name.
Assumptions are yours to overturn
Every assumption is visible and editable. Overturning one re-runs the checks that depended on it.
Sign-off remains an engineering act
Suyantra can tell you the design is not yet defensible. It cannot tell you it is finished.
Look at what sits underneath.
