High-Speed PCB Design

What is High-Speed PCB Design?

High-speed PCB design refers to electronic circuit design that contains signals operating at high-frequencies or fast edge rates. These designs require special considerations to ensure proper signal integrity, timing, and electromagnetic behavior. High-speed PCB designs typically include high-speed interfaces such as DDR, PCIe, USB, HDMI, SATA, SerDes, or Gigabit Ethernet.

Benefits

Fast Data Transmission
Improved Signal and Power Integrity
Increased System Reliability
Consistent, Predictable Performance

Try High-Speed PCB Design with OrCAD X

High-Speed PCB Design in OrCAD X

OrCAD X contains the features required to plan, execute, and verify your high-speed PCB designs. With the powerful constraint manager, configuring rules to ensure proper functionality of your high-speed nets is simple. Real-time feedback and advanced routing capabilities help to complete your PCB layout accurately and efficiently. Then verify performance with in-design signal integrity analysis to evaluate impedance and signal coupling directly in the PCB canvas.

Key Features of High-Speed PCB Design in OrCAD X

OrCAD X and Allegro X contain the functionality you need to accurately and efficiently complete your high-speed PCB designs.

Impedance Control

Built-in field solvers help you determine the required line width and spacing for your desired differential impedance taking the PCB stackup and materials into consideration. Then easily adhere to these impedance requirements by defining, tracking and managing the desired impedance and tolerance for critical high-speed nets and Xnets in your PCB designs within the constraint manager.

Differential Pair Definition and Routing

Easily define differential pair rules including primary gap, neck gap, gather control, line width, maximum uncoupled length, phase tolerance, and more. Differential pair traces are routed together, according to the defined rules to ensure proper functionality and noise immunity.

Pro

Delay and Phase Tuning

Quickly meet timing requirements by adding delay tuning or phase tuning to high-speed nets in your PCB designs. Easily configure the tuning, defining the pattern, gap, corners, and more and verify timing requirements are met with a color-coded heads-up display.

Pro

Signal Integrity Analysis

Analyze common signal integrity issues such as impedance discontinuities and signal coupling to ensure proper functionality of your high-speed nets. With direct access to in-design impedance and coupling analysis, you can evaluate performance, pinpoint issues, modify the design, and verify functionality during the PCB layout when change is easiest.

Pro

Length Matching

Define constraints for min/max propagation delays, total etch length, and relative propagation delays to meet the timing and phase requirements of your high-speed nets. Real-time design rule checking helps you achieve proper functionality efficiently.

Constraint Management

The expansive constraint manager in OrCAD X allows you to configure and assign the required rules for your critical, high-speed nets to ensure proper operation. Define rules or sets of rules for electrical, physical, spacing, and manufacturing requirements and quickly assign the rules to multiple nets. Easily reuse constraints between designs for to quickly configure your high-speed devices with quick import and export of rules.

Pro

Real-Time Routing Feedback

A color-coded heads-up display provides real-time feedback in the PCB canvas during routing, allowing designers to verify traces will adhere to length matching, timing requirements, and phase requirements during routing.

XNet Definition and Management

Automatically identify and create extended nets or XNets to manage high-speed signals between components, including all passive or discrete devices such as resistors, capacitors, or inductors. Easily define, assign, and manage rules for Xnets in constraint manager to ensure performance of your high-speed design.

Pro

Topology Extraction and Exploration

Extract critical topologies, such as Xnets, from the PCB design to analyze signal integrity and determine the optimal rules to meet functionality and performance requirements for your high-speed designs.
