What to upload
Upload an Allegro `.brd` for board import, or a Cadence `(NETLIST)` text extract for packages and pins. Write `allegro-netlist` for Cadence text; Specctra DSN is a separate Cadence router exchange, not ODB++.
Board CAD
Cadence Allegro file conversion
Recognized board files can supply layout data; text extracts provide limited component information.
In development — results may be incomplete or inaccurate.
What to review
Native `.brd` records still need the CAD reader. The Allegro text netlist is Cadence’s own package/net grammar.
Conversion outputs
These routes depend on supported source contents. Each upload receives its own result and notes. Shared editor engine for supported board and authored schematic profiles. Coverage and independent qualification are reported separately.

Practical file guides
- PCB file extensions: identify BRD, PCB, Gerber and netlist files
Identify ambiguous .brd, .pcb and .dsn files before conversion. Learn which PCB files contain layout, manufacturing layers or electrical connections.
