How to Design PCBs with Cadence OrCAD Allegro 16.6
Cadence OrCAD Allegro 16.6 is a powerful software suite that enables you to design printed circuit boards (PCBs) from the simplest to the most complex. Whether you are a beginner or an expert, you can benefit from the many features and enhancements that Cadence OrCAD Allegro 16.6 offers.
In this article, we will show you how to use Cadence OrCAD Allegro 16.6 to create a PCB design from scratch, including schematic capture, layout, routing, simulation, and verification. We will also highlight some of the key advantages of using Cadence OrCAD Allegro 16.6 over other PCB design tools.
Schematic Capture with Cadence OrCAD Capture
The first step in any PCB design process is to create a schematic diagram that represents the circuit functionality and connectivity. Cadence OrCAD Capture is a user-friendly and intuitive tool that allows you to draw schematics quickly and easily. You can access a large library of symbols and footprints for common components, or create your own custom symbols and footprints using the Allegro PCB Librarian[^2^]. You can also import netlists from other tools or export your schematic to other formats.
Cadence OrCAD Capture also supports hierarchical design, which means you can organize your schematic into blocks and sub-blocks for better readability and modularity. You can also use the Allegro Design Workbench[^1^] to manage your design data and collaborate with other team members across different locations using Microsoft SharePoint 2010[^1^]. You can compare constraints, track changes, and synchronize data between different versions of your schematic.
Layout with Cadence Allegro PCB Editor
Once you have completed your schematic, you can transfer it to Cadence Allegro PCB Editor for layout. Cadence Allegro PCB Editor is a comprehensive tool that allows you to create high-quality PCB layouts with advanced features such as shape-based autorouting, interactive etch editing, differential pair routing, constraint-driven design, and 3D visualization. You can also use the Allegro FPGA System Planner[^1^] to optimize the pin assignment and placement of FPGA devices on your board.
Cadence Allegro PCB Editor supports both rigid and flexible PCB designs, as well as mixed-signal and RF designs. You can use the Allegro PCB RF Option[^1^] to perform RF-specific tasks such as impedance matching, transmission line modeling, and antenna design. You can also use the Interactive3D engine[^2^] to view your layout in 3D and check for mechanical interference with other components or enclosures.
Routing with Cadence Allegro Router
Cadence Allegro Router is a powerful tool that automates the routing process for your PCB layout. It uses shape-based algorithms to route traces according to your design constraints and rules. You can control various aspects of routing such as layer assignment, via patterns, trace width, spacing, length, delay, crosstalk, etc. You can also use interactive routing features such as push-and-shove, glossing, sliding, tuning, etc. to fine-tune your routes manually.
Cadence Allegro Router also supports high-speed routing for critical signals that require precise timing and impedance control. You can use the Allegro TimingVision Environment[^1^] to speed up timing closure of high-speed interfaces by up to 67%[^1^]. You can also use the auto-interactive route delay tuning feature[^1^] to adjust the trace length and delay of high-speed signals by 30-50%[^1^]. Additionally, you can use the Sigrity technology portfolio[^1^] to perform signal integrity analysis and power integrity analysis on your routed board.
Simulation with Cadence PSpice
Cadence PSpice is a powerful simulation tool that allows you to verify the functionality and performance of your circuit before fabrication. You can simulate analog, digital, mixed-signal, and RF circuits using PSpice models for various components such as transistors, d
