Matching trace lengths for large-bit buses and differential pairs in your design is vital. However, this can be a tedious process and mismatched lengths can result in signal quality and integrity issues. Signals may need to be synchronized with clocks and unmatched differential pairs create additional noise. Any of these issues can be detrimental to your design. However, by automating the process you can improve signal quality and reduce time and errors, allowing you to focus on more important aspects of the design. OrCAD helps you do this with constraints for Net Groups. Create Constraints for minimum and maximum propagation delay in mils, nanoseconds or percentage. Or set constraints for total etch length. Create Net Groups and assign the constraints to all the nets in a group. Analyze the constraints without ever leaving the Constraint Manager. DRC Markers flag any incorrect lengths in real-time. Eliminate the need to check each individual net with OrCAD PCB Designer.

Maintaining the rules for tight pin areas can be timing consuming. Manually making changes to tight-pin areas takes up time you could be using to concentrate on more important tasks. OrCAD helps you eliminate the need for manual checks and changes through constraint regions. You define constraints physical and spacing constraints for specific regions and OrCAD automatically follows these constraints when routing.

Getting arcs equally spaced when routing a bus around a curved, flex circuit is not easy. With routing software offering a grid-based approach, this often leads to sloppy spacing and inadequate contour routing. However, with OrCAD contour etch routing, the software understands you are routing a bus with a unique contour and gives you the ability to specify the spacing between each one. This allows it routes to be completed uniformly and correctly spaced, all while performing DRC checks along the way to ensure you are adhering to set rules.

Flex PCB design has many advantages. In fact, the global market for flex/rigid-flex boards more than doubled in the past 4 years alone. Along with those benefits come new design challenges that weren’t present in “standard” 2D PCBs. Learn about common flex design issues and how to design to help you catch them before they become a problem. Become a flex PCB design master with tips from the experts at EMA in this webinar.

Prevent time-to-market delays by identifying manufacturing issues before they become a costly mistake. It’s not uncommon for designs to be submitted to manufacturing only to have problems identified that require design reworking and re-submission. This results in lost production time, schedule delays, and recurring tooling costs. What if you could identify DFM problems as you design and fix them when they happen? This webinar will help show you how to spot and fix troublesome DFM issues in-design before they ever become a problem.

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 Capture interface and can help define and embed constraints at the beginning of the design process—ensuring they will be communicated clearly. In addition to the overview on constraint-driven design, Janine Flagg, one of our senior field applications engineers, provided an in-depth demo on the product and answered any questions attendees may have had.

The inclusion differential pairs within a design introduces a wide variety of concerns engineers need to be mindful of if they want them to be reliable. Differential pairs are prone to problems if routing requirements and other guidelines are not followed, therefore it is imperative they are done correctly and design rules are always defined and adhered to. To help you as you navigate these rules and help provide some clarity on the topic, we have created an infographic: The Anatomy of a Differential Pair.

In such an innovative and technology-driven industry, why are you still defining and communicating constraints outside of your CAD environment? With Constraint Manager for OrCAD you can define and embed constraints initially and know that they will be communicated clearly throughout the design cycle.
