Can I create a schematic from a .brd file? I guess the schematic went missing.
Cadence 16.3 PCB and Cadence 16.3 Design entry HDL.
Elgris Technollogies (www.elgris.com) has the software to generate schematics from a netlist you can extract from Allegro PCB.
The generated schematic can be saved to Concept (Design Entry ) HDL or to OrCAD Capture.
The generated schematic will look different from your original schematic, because all the graphics is generated.
