Orcad 16.6 — Tutorial _verified_

The installation process for Cadence SPB (OrCAD/Allegro) 16.6 involves several critical steps:

is a foundational electronic design automation (EDA) software suite from Cadence that combines several powerful modules: Capture for schematic entry, PSpice for circuit simulation, and PCB Editor for board layout and routing. While newer versions exist, 16.6 remains widely used in academic settings and industry due to its reliability and extensive support resources. This tutorial will guide you through the entire design flow from installation, schematic capture, simulation, to PCB layout in OrCAD 16.6.

Each schematic symbol needs a corresponding physical footprint (e.g., 0805 , TO220 , LQFP48 ). Select the design file in the project manager. orcad 16.6 tutorial

Even with a perfect tutorial, errors occur. Here’s how to fix the top three.

If your project requires functional testing before physical layout, use the integrated PSpice engine to analyze circuit behavior. Setting Up Simulation Profiles Go to . The installation process for Cadence SPB (OrCAD/Allegro) 16

. Ensure you select "PC Board Wizard" if you plan to move to a physical layout later. Adding Parts Place > Part menu. If a component is missing, you can create a in your own library by right-clicking your file and selecting External Libraries : For complex parts, use tools like Ultra Librarian (accessible via Accessories > Ultra Librarian in Capture) to download pre-built symbols and footprints. : Connect pins using the Place Wire Net Aliases

Place crucial structural connectors, switches, and mounting holes first. Here’s how to fix the top three

By following this workflow, you have successfully navigated the core functions of OrCAD 16.6 Capture. You have set up a project, built a logical circuit, and prepared the data for physical manufacturing.

🔧 Tip: For simulation, parts must have PSpice models (e.g., uA741 , 1N4148 , R from ANALOG lib).

By following this tutorial, you have navigated the entire PCB design flow using one of the most reliable and widely-used EDA platforms in the industry. From initial schematic to final manufacturing files, OrCAD 16.6 provides a complete and robust solution for bringing your electronic ideas to life.

Create your structural physical board boundary by going to . Importing the Components Go to File > Import > Netlist . Ensure the Design entry method is set to OrCAD Capture .
