OrCAD is a proprietary software tool suite used primarily for electronic design automation (EDA). The software is used mainly by electronic design engineers and electronic technicians to create electronic schematics and electronic prints for manufacturing printed circuit boards.
The name OrCAD is a portmanteau, reflecting the company and its software's origins: Oregon + CAD.
OrCAD is a suite of products for EDA, and includes a schematic editor (Capture), a circuit simulator (PSpice) and a PCB designer.
OrCAD Capture is a schematic capture application, and part of the OrCAD circuit design suite.
Unlike NI Multisim, Capture does not contain in-built simulation features, but exports netlist data to the simulator, OrCAD EE. Capture can also export a hardware description of the circuit schematic to Verilog or VHDL, and netlists to circuit board designers such as OrCAD Layout, Allegro, and others.
Capture includes a component information system (CIS), that links component package footprint data or simulation behavior data, with the circuit symbol in the schematic.
Capture includes a TCL/TK scripting functionality that allows users to write scripts, that allow customization and automation. Any task performed via the GUI may be automated by scripts.
The OrCAD Capture Marketplace enables customers to share and sell add-ons and design resources. Such add-ons can customize the design environment and add features and capabilities.
Capture can interface with any database which complies with Microsoft's ODBC standard etc. Data in an MRP, ERP, or PDM system can be directly accessed for use during component decision-making process.
