Ortec, developed by Cadence, is the most widely used tool for schematic design and has become an industry standard. In this tutorial, Xiaobian will guide you through the process of setting up the OrCAD environment.
OrCAD is a comprehensive suite of electronic design automation (EDA) software designed for personal computers. It enables electronics engineers to create schematics, related diagrams, printed circuit board (PCB) layouts, and even simulate circuit behavior. The name "OrCAD" is a combination of "Oregon" and "Computer-Aided Design," reflecting its origins.
**1. Setting Up the Working Environment**
Before starting with OrCAD, it's essential to configure your working environment to suit your preferences and improve productivity.
Go to **Options > Preferences**, which opens a settings window as shown below:
Here are some key settings:
- **Colors/Prints**: This section allows you to define the colors for various elements such as graphics, components, and network aliases. You can also set the color for the background, buses, and DRC markers. While default settings work well, you can customize them based on your preference.
- **Grid Display**: This option controls how the grid appears on the screen. You can choose to display or hide the grid, use dots or lines, adjust the spacing between grid points (default is 1), and decide whether the cursor should snap to the grid.
- **Pan and Zoom**: This tab lets you adjust the zoom level of the schematic and component editor windows, as well as enable auto-scrolling for easier navigation.
- **Select**: This setting defines how selected objects are highlighted. You can adjust the color and style of the selection to make it more visible.
- **Text Editor**: Customize text editing features such as font size, color, and syntax highlighting for better readability.
- **Board Simulation**: Configure simulation settings for PCB layout and circuit analysis.
By properly configuring these settings, you can significantly enhance your experience while using OrCAD, making it more efficient and tailored to your workflow.
