What is an OLB file

OLB files mostly belong to OrCAD PCB Designer by Cadence. An OLB file is an electronic component symbol library used by Cadence electronics design automation programs such as PSpice and OrCAD PCB Designer. It contains multiple symbols of components used in electronic schematic design/capture. OLB is also the filename extension of an object automation library used by Office productivity software suite. This OLB file contains data types, functions, and the properties/methods of objects available to process automation controllers such as Visual Basic and C++ tools used to create embedded applications for Office. Another type of OLB file is an object library used by Synergy/DE software development suite.

How to open OLB files

You need a suitable software like OrCAD PCB Designer to open an OLB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your OLB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a OLB file directly in the browser:. Just drag the file onto this browser window and drop it.

OLB format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. If there are problems opening a file, you must first determine the file format used. In the following you will find our evaluation of the OLB files:

The OLB file type is a very commonly used file extension and is used by a few programs, each with its own file format. The two most common formats are as follows:

60% of all OLB files utilize the Microsoft Compound File format, also known as Composite Document File format or OLE2 compound document format. This general-purpose file format provides a file-system-like structure within a file for the storage of arbitrary, application-specific streams of data. Header signature for the CFB format with 8-byte Hex value D0CF11E0A1B11AE1 (which looks like "DOCFILE"). The file contains several sections which are named like Cache, Cells, Graphics, Library, Packages, Parts, Symbols, Views, Cells Directory, ExportBlocks, ExportBlocks Directory, Graphics Directory, Packages Directory, Parts Directory, Symbols Directory, Views Directory and NetBundleMapData. OLB files can be up to 11 MB in size, but are often around 6 KB - 340 KB. The file type was created 20 years ago but is still used today. These files are often associated with symbol, library, orcad, core, zynq, fpga, latticeplds, analog and gowin.
30% of all OLB files belong to Object Library. The files are using the common file format EXE. EXE is the abbreviation for executable and is the standard executable file format on Windows. The format can be identified by the letters "MZ" at the beginning. Executable files can also be used to distribute viruses and other types of malicious software (malware). They consist of illegible, cryptic characters. The file size is in the range of 23 KB to 630 KB. The following keywords are characteristic: !This program cannot be run in DOS mode and Rich. Examples of file names are MSADDNDR.OLB or VBE6EXT.OLB. Files like these are about msword, excel, msacc, msoutl, msppt and esri.

All other OLB files (10%) have no consistent format, the following 4 formats exist: ROS. Often described as wolfspeed, pspice, fpgaxc, board, model or power. Drag & drop your file here to see the file format and a preview of your OLB file!

How to solve problems with OLB files

Associate the OLB file extension with the correct application.
Update your software that should actually open symbol models librarys. Because only the current version supports the latest OLB file format. Search, therefore, e.g. on the Cadence manufacturer website after an available OrCAD PCB Designer update.
To make sure that your OLB file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
