How can I get the free Allegro viewer?
If you have the software release installed on your machine then the Allegro Free Viewer is installed into the following directory path: C:\Cadence\SPB_17.2\tools\bin\allegro_free_viewer.exe
The path for version 17.4 is: C:\Cadence\SPB_17.4\tools\bin\allegro_free_viewer.exe
After you have the viewer successfully installed, you can access read-only files created in OrCAD Capture and OrCAD/Allegro PCB Editor. The free viewer provides the following capabilities:
- Open and View schematics (.DSN .OPJ .OLB) and PCB Editor (.BRD) files
- Measure and dimension tools
- Cross-probe from schematic to PCB Editor
To use the Intercommunication tool to cross probe between Capture and PCB Editor using the Viewer, you need to select the Capture menu items: Options > Preferences and then check the Enable Intertool Communication selection box available from Miscellaneous tab.
