Turn Requirements into Functions and an FFBD

Derive functions from a requirements document, arrange them into a flow, draw the FFBD and produce the tables and report.

Open Behavior → Functional Analysis, or in the document choose More ▾ → Functional Analysis (functions, FFBD, tables)…. Pick the document in the scope list.
On the Functions tab, click Rule-Based Extraction… (one function per functional requirement), or choose ✦ AI ▾ → Extract Functions with AI….
In the preview, rename, merge or split functions, reassign requirements by number, set parents and the top-level function, then Apply. Each function becomes a numbered Action and each requirement is linked satisfied by its function.
On the Flow & FFBD tab, select blocks and use Wrap in AND, Wrap in OR, Wrap in LOOP, Unwrap and + Branch, or Edit as Text…. ✦ AI ▾ → Suggest Flow with AI… proposes an order, branches and loops.
Click Open FFBD to see the diagram; set the orientation and start/end labels there.
On the Tables tab, copy or download the requirements table and the functions table (Copy, CSV, XLSX, DOCX). Run Quality Check fills the Score column.
Click Assignment Report (DOCX) for one Word file with the requirements table, the FFBD and the functions table, with captions.
Check the Coverage tab for requirements without a function and functions without a requirement.

Running the extraction again updates the existing functions instead of adding copies; they keep their names unless you choose Rename.
