Routing DDR and high-speed bus interfaces can be one of the most daunting tasks in your design. Just getting all the various signal relationships and requirements defined and understood can feel like a PhD thesis on its own. With the new bus designer, all you need to do is simply describe the bus you are trying route and Constraint Manager for OrCAD will handle generating the appropriate constraints automatically.

Geometric Dimensioning and Tolerancing for the PCB Designer
As we continue to shrink the electronics in our lives, the need for concise documentation grows more important at each node. The dimensions we provide are the determinants of success.
What is the Importance of Tolerance in Manufacturing?
Achieving precise tolerances throughout your PCB design reduces errors and speeds the design to manufacturing process.
Constraint Driven Design - Overview
A constraint driven approach makes your PCB design process smoother. Eliminate the need for multiple design reviews as well as shorten the overall design process.
Easily reuse validated constraints and improve design quality and time to market.

Real-Time Dynamic Differential Pair Routing
Easily meet length and phase pin-to-pin constraints as traces bend without creating electrical issues.
Making the Little Things Count on Your PCB Design
Even as everything related to electronics shrinks in size, a few small areas that we have been able to ignore so far remain. Along with the physical reduction, we also encounter reductions in our...
Front End Constraints
Capture electrical constraints early in the design process and automatically communicate them to PCB layout designers directly from the circuit schematic environment.
How To: HDMI
High Definition Media Interface is a beautiful thing. Back when 1080P meant something, the HDMI spec entered the scene as an upgrade on the legacy trio or quintet of RCA cables. The number of...
How (and Why) to Embrace Design Constraints
Design rules are nothing new. Our ability to create specific and concrete rules to govern the results should not be overlooked. From the first placement study to the final result, capturing a...
Minimizing Routing Iterations on Complex, High-Density PCBs with OrCAD Tools
Quickly route complex, high-density boards for a variety of applications, including industrial- and military-grade designs
Working with OrCAD: Constraint Manager
This week’s Working with OrCAD video, Constraint Manager 2, discusses how the constraint manager within OrCAD products constitutes the central focus point. This allows the designer to control the...
5 Ways to Assess PCB Constraint Management Systems for High-Speed Designs
A sound constraint management design process helps to foster a correct-by-design approach, reduces time-to-market, and ultimately optimizes the design process—eliminating the undefined,...
Common Questions About Constraint-Driven Design with OrCAD Capture
Our most recent webinar, Constraint-driven design with OrCAD Capture, provided attendees with an overview of Constraint Manager for OrCAD. It is a new option available directly within the OrCAD...
Set it and NEVER Forget it with Constraint-Driven PCB Design
Setting up and implementing a constraint-driven design flow may seem like a daunting planning task, however spending the time upfront can save you hours (or even days) by preventing design...
Right-first-time design with the constraint-driven flow in OrCAD
OrCAD helps you design better by providing real-time visual feedback for electrical, physical and spacing constraints so you can easily avoid and fix violations.
