About EDA Viewer
Preview electronic design files including Cadence symbol libraries (OLB), GDSII/OASIS layout data. Inspect layers and geometry of IC/PCB designs in the browser.
How to Use
Upload or drag in an .olb, .gds/.gdsii, .oas, .dra, or .brd file. The viewer parses the binary format locally and renders the relevant layers.
Privacy
Designs are parsed and rendered entirely in your browser. The file is never uploaded to a server.
▶Which formats are supported?
Cadence OLB libraries, GDSII (GDS), OASIS (OAS), and Allegro DRA/BRD. Vendor-locked or proprietary encryptions are not supported.
▶Why are some layers missing?
EDA viewers typically render a default visible layer set. If expected geometry is absent, the file may reference external technology or symbol files that aren't bundled.
