OrCAD PCB Designer Lite
OrCAD Lite is a free software that allows for evaluation and experimentation with OrCAD PCB software; introducing users to all the features and functionality available in OrCAD technology. OrCAD Lite is designed to give users a real life OrCAD experience, and is a great introductory PCB design tool for the less experienced designer. Demos in the Lite version include an OrCAD-level PCB Editor, OrCAD Capture, CIS, SPECCTRA for OrCAD, PSpice A/D, and advanced analysis.
OrCAD PCB Designer Standard
OrCAD Standard replaces older basic versions of OrCAD. Features include schematic entry, PCB editing, manufacturing outputs, 3D visualization, and the option to add component data management, FPGA PCB co-design, and full signal integrity analysis.
OrCAD PCB Designer Professional
OrCAD Professional includes more functionality for constraint management, advanced PCB editing, and upgraded placement. The Professional Suite brings advanced technology to the mainstream, allowing designers to define rules in the initial stages of the design process using a simple spreadsheet interface. This constraint-driven design flow accelerates the time to first-pass design success, while reducing the overall costs of end products. With constraint manager you can define rules for: Individual nets, differential pairs, regions, specific layers, specific rules for nets on layers, and more.
PCB Designer Professional allows for advanced PCB editing by providing full differential pair support. This support allows for automatic pair generation, interactive routing, and real time rule checking using Constraint manager. Users can receive instant feedback on whether they are meeting routing requirements with a real-time heads up display. Automated testpoint and fixture generation is also included in the Professional Suite.
