The availability of the 17.4 Physical Viewer has tangible impacts on the speed and quality of hardware development. Consider a scenario where a layout engineer finishes a design in Allegro 17.4. They package the .brd file and send it to a fabricator in Shenzhen. The fabricator’s CAM engineer, using the free viewer, can immediately inspect the stack-up and impedance control layers. If the viewer were not free or easily accessible, the engineer would have to export the design into a neutral format like ODB++. This conversion process takes time and introduces the risk of data corruption. The viewer preserves the "single source of truth"—the native design file—throughout the review process.
