OrCAD PCB Designer STEP models provide a realistic three dimensional representation of your design Real-Time Coupling Real time Route Dynamic copper shapes Dynamic copper shape technology offers real-time copper pour plowing and healing functionality. Shape parameters can be applied at three different levels: global, shape instance, and object-level hierarchies. Traces, vias, and components added to a dynamic shape will automatically plow and void through the shape. When items are removed, the shape automatically fills back in. Dynamic shapes do not require batch autovoiding or other post-processing steps after edits are made. Placement replication and reuse Intelligent placement replication technology enables you to automatically place and route replicated circuits using a seed circuit that is applied to other circuit instances within the design. Changes made to the seed circuit are automatically propagated to the duplicated circuits. Circuit templates with "known-good" placement and routing can be reused in other designs with similar circuits. Constraint Manager Design rules and electrical and physical constraints are more critical to your projects' success than ever before. Dealing with all the complexities of the rules and constraints of a modern design requires a powerful constraint management system capable of covering all the aspects of creation, management, and validation. The OrCAD PCB constraint management system displays physical/spacing, samenet, region, and differential pair and length rules along with their status (based on the current state of the design) in real time and is available at all stages of the layout process. Each worksheet provides a spreadsheet interface that enables you to easily define, manage, and validate the different rules in a hierarchical fashion. The constraint management system is completely integrated within the OrCAD PCB design solution, and constraints can be validated in real time as the design process proceeds. The result of the validation process is a graphical representation of whether constraints pass (highlighted in green) or fail (highlighted in red). This approach allows you to immediately see the progress of the design in the spreadsheets, as well as the impact of any design changes. High Speed Constraints-Driven Autorouting in PCB Designer Professional Increasing use of standards-based advanced interfaces such as DDR3, DDR4, PCIe, USB 3.0 are bringing a set of constraints that must be adhered to while implementing a PCB. The OrCAD PCB Designer Professional now makes adhering to high speed constraints on advanced interfaces quick and easy. High-speed routing constraints and algorithms handle differential pairs, pin delay, nested net groups, Z-axis delay requirements demanded by today's high-speed circuits. The autorouting algorithms intelligently handle routing around or through vias, and automatically conform to defined length criteria. Separate design rules may be applied to different regions of the design; for example, you can specify tight clearance rules in the connector area of a design and less stringent rules elsewhere. Real Time PCB Design will shorten time to identity and fix High Speed signals in Real-time with visual feedback using Real-Time Impedance, Real-Time Coupling and Real-Time Route. This is an innovative and unique environment that allows users to graphically see real time delay and phase information directly on the routing canvas. Traditionally, evaluating current status of length of a routed interface required numerous trips to Constraint Manager and/or use of the Show Element command. Using an embedded route engine to evaluate complex timing constraints and interdependencies amongst signals shows current status of a set of routed signals—a DDRx byte lane or a complete DDRx interface— via custom trace/connect line coloring; stipple patterns and customized data tip information to define the delay problem in the simplest terms possible. This functionality is now available in the OrCAD PCB Designer Professional. Designing Rigid-Flex Rigid-Flex substrates are becoming common in IoT, wearables, and mobile smart devices as well as in medical devices and even automotive. In the OrCAD PCB Layout editors, a designer can define multiple substrate material cross-sections as well as area- dependent rules to meet Rigid-Flex design and 3
