New EMA Constraint Manager for OrCAD Brings True Collaboration to the Design Process


Reading time ( words)

EMA Design Automation today announced the release of EMA Constraint Manager for OrCAD to ensure design intent is communicated and adhered to during PCB implementation. "Today's electronics pack an enormous amount of technology and features into smaller packages," said Manny Marcano, president and CEO of EMA. "At every step of the design process, design issues are compounded because of the interrelated constraints and poor communication of constraints between different functional groups. Constraint Manager for OrCAD allows OrCAD Capture to be an integral part of the Cadence Allegro constraint driven flow paradigm, providing a structured way to manage constraints across all tools in the Cadence PCB design flow. This reduces design iterations, improving design quality and time-to-market.”

With Constraint Manager for OrCAD, designers can easily embed design constraints directly into the OrCAD schematic. Using a smart spreadsheet interface, users can constrain nets by adding electrical, physical, and spacing rules for routing those nets. This not only ensures nets are routed properly, but it also reduces the time required for a PCB designer to route the nets. Constraints can be set on individual nets or groups of nets. Commonly used sets of constraints can be organized into CSets and applied to CM objects by CSet name. Constraint Manager for OrCAD has full support for PinPair, Net, XNet, Differential Pair, Bus, NetGroup, NetClass, and MatchGroup objects. Constraint Manager for OrCAD includes a Differential Pair viewer to help users visualize how rules will be applied during physical implementation. These capabilities make the process of constraining a design fast and efficient.

Constraint Manager for OrCAD stores constraints in the OrCAD Capture design file, so there is no need to manage constraints and designs. Since some constraints are dependent on layout specifics, Constraint Manager for OrCAD integrates with the Allegro Constraint Manager to share constraint information. This allows stackup information to be back-annotated and also allows for the bidirectional transfer of physical, spacing, and electrical constraints. Constraints can also be saved separately from a design so that they can form a constraint library to be shared between designs.

“Adding constraints early in the design process ensures that the design intent is communicated and adhered to throughout PCB implementation,” added Marcano. “Constraint Manager for OrCAD brings structure and discipline to the PCB design process making it much easier to create the best designs possible.”

Susy Webb: Training the New Generation of Designers

08/02/2018 | Andy Shaughnessy, Design007 Magazine
For years, I’ve been running into Susy Webb at PCB West, where one of the classes she teaches is PCB design basics. I always ask Susy about the class, especially the attendees’ backgrounds. Over the years, her class has begun drawing more and more degreed engineers, with fewer “traditional” PCB designers attending. I asked Susy to discuss the next generation of PCB designers, some of the trends she’s seeing among new PCB designers, and the need for designers to take charge of their own design training, whether their management agrees or not.

Multi-board Design with Altium’s Ben Jordan

07/25/2018 | I-Connect007 Editorial Team
Not too long ago, historically speaking, most electronic products contained only one PCB. But multi-board designs have become almost ubiquitous over the past decade, and EDA software companies are working to improve and simplify the multi-board design process. Editors Andy Shaughnessy and Stephen Las Marias spoke with Ben Jordan, director of product and persona marketing for Altium, about the company’s multi-board design tools, the challenges that customers face, and the numerous trade-offs that designers must contend with while performing multi-board design.

3D Convergence of Multiboard PCB and IC Packaging Design

07/18/2018 | Bob Potock, Zuken
A new generation of 3D multiboard product-level design tools offer major improvements by managing multiboard placement in both 2D and 3D, and enabling co-design of the chip, package and board in a single environment. Multiboard design makes it possible to create and validate a design with any combination of system-on-chips (SOCs), packages, and PCBs as a complete system.
