Format coverage depends on file version and dialect. Reader inspection complements but does not replace sign-off CAD tools.
ENGINEERED FOR INSPECTION
Trace signals instantly.
Understand the whole board.
From full-board copper topology down to individual BGA balls and test pins—always maintain clear visibility between physical layout and logical intent.
Dense Multi-Layer Navigation
Isolate copper layers, inspect pad geometry and net connections, and keep your bearings with the overview radar. Detach views into dedicated multi-monitor windows as needed.
Complete Design Context
Navigate continuous multi-page schematics on an unconstrained canvas alongside vector PDF datasheets. Search pinouts and component properties with everything in immediate reach.

From raw design files
to live net inspection.
Open Projects or Standalone Files
Open board files, multi-sheet schematics, or datasheets directly via drag-and-drop or Ctrl+O. Loading project containers automatically binds PCB and schematic drawings together.
Track Components and Signals
Toggle Linked Navigation to activate bidirectional cross-probing. Select components or nets to focus counterparts; ambiguous or multi-unit candidates are surfaced for inspection.
Tailor Your Workspace
Switch between calibrated dark and light themes, configure copper grids, engage X-ray layer perspective, or undock canvases across dual-head display rigs.
Are design files uploaded to external servers?
Never. All CAD parsing, netlist extraction, and rendering execute entirely inside your local process. Your proprietary hardware IP never leaves your workstation.
Does this tool support PCB editing or DRC sign-off?
Keltri Reader is purpose-built for fast inspection, cross-probing, and board bring-up. It is not an autorouter, layout editor, or manufacturing DRC engine.
Why might Windows show a publisher warning?
The reader and installer are not code-signed, so Windows may show an unknown-publisher warning. Download from keltri.app; the published SHA-256 digest lets you check file integrity and is not a code signature.
