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.”

This article briefly introduces the 4-level pulse amplitude modulation (PAM-4) and its application in 400 Gigabit Ethernet (400GbE), to support the booming data traffic volume in conjunction with the deployment of 5G mobile communications. Furthermore, this article also highlights the essential pre-layout effort from signal integrity perspective for physical (PHY) link design on a PCB, including material selection, transmission line design and channel simulation to support 56Gbps data rate that paves the way for seamless communication in 400GbE.

Excerpt: The Printed Circuit Designer’s Guide to…Flex and Rigid-Flex Fundamentals

06/25/2018 | Dave Lackey and Anaya Vardya, American Standard Circuits
The design process is arguably the most important part of the flex circuit procurement process. The decisions made in the design process will have a lasting impact, for better or worse, throughout the manufacturing cycle. In advance of providing important details about the actual construction of the flex circuit, it is of value to provide some sort of understanding of the expected use environment for the finished product.
