World’s Largest PCB CAD Library Offers Free Access


EDA solutions provider EMA Design Automation is providing free access for its more than 14 million component library, Ultra Librarian, allowing engineers to download from a large collection of verified symbols, footprints, and 3D STEP models through This will help save engineers’ time doing tedious work of creating library parts and maintain focus on their primary task of designing circuits, the company said.

Ultra Librarian contains symbols, footprints, and 3D models for over 14 million electronic components, making it the largest EDA model library in the world.

EMA also said that it has worked closely with component manufacturers and has doubled the size of the library from seven million to over 14 million parts in less than two years.


According to the firm, this rate of growth was achieved by using the Ultra Librarian Desktop software, which uses a sophisticated combination of templates, pdf extraction, and verification algorithms to quickly capture all important component information necessary to create the unique library components required for over 20 CAD model formats, including Altium, Eagle, KiCad, OrCAD, and PADS.

To ensure the highest accuracy, consistency, and adherence to IPC standards, models undergo more than 30 different verification checks.

Ultra Librarian also helps with the mechanical side of PCB design by offering 3D STEP models for the vast majority of the parts in the library.

“Many electrical engineers and PCB designers do not have the tools or the mechanical expertise to create 3D models,” said Marcano. “Their primary focus is the electrical side of the problem, so being able to download a 3D model together with the symbol and footprint saves a lot of time and eliminates many errors. Ultra Librarian 3D component models are available in STEP format providing superior compatibility with virtually all 3D CAD systems, including SOLIDWORKS and Autodesk Inventor.”

“By removing the barrier of cost, we’re making EDA library components far more accessible, allowing every designer to create designs faster and with fewer errors,” added Marcano. “This is just the next step in our quest for us to build the ‘Gold Standard’ of EDA libraries.”
