Project schematics are produced in either xDxDesigner (part of PADS VX) or Altium Designer® using Vault based design. All components in a schematic are pulled in from an ODBC database that maps the graphical symbol, IPC7351 compliant footprint & 3D model.
All the design intelligence especially for high speed designs is stored in the project file. BOM generation is thus only a one click process.
Using disciplined schematic capture creates a smooth flowing process for product design.
