ZIP archive of 3.86 MB holding Allegro Physical Viewer version 15.7, the free Cadence viewer for Allegro PCB database files. Repair technicians use it to open native .brd layouts from Allegro, where they can search components, highlight nets, inspect copper layers and find test points that simpler boardview tools may not show. Note that Allegro .brd files differ from other formats sharing the same extension, so a file that fails here may need OpenBoardView or FlexBV instead. Scan the installer before use.
