OrCAD PCB Designer manufacturing guidelines. New Flex focus arc routing and Flex bend editor provide the designer with the necessary tools to manage the complex Rigid-Flex or pure Flex designs. 3D Display and Visualization The OrCAD 3D viewer environment gives you the ability to see a realistic, three-dimensional representation of your design. The environment supports several filtering options, camera views, graphic display options such as solid, transparency and wireframe, and controls for panning, zooming, and spinning the display. 3D viewing also supports the display of complex via structures or isolated sections of the board for viewing more details. With support for the STEP format and models, the OrCAD PCB design solution supports the import of model-accurate component and mechanical elements, such as an enclosure, to view in the context of your PCB project. This allows you to perform visual clearance checks to detect clashes early on and ensure you will have proper fit when you move to manufacture. PCB Manufacturing The OrCAD PCB design solution supports a full suite of phototooling and bare-board fabrication, and test outputs can be generated including Gerber 274x, NC drill, and bare-board test in a variety of formats. The OrCAD PCB design solution also supports the industry initiative toward Gerber-less manufacturing through the export (and import) of design data in the IPC-2581 format. The IPC-2581 data is passed in a single file that creates accurate and reliable manufacturing data for high-quality manufacturing. You have a choice to export a subset of the design data for protecting design IP. Design Solutions and Flows Topology exploration with signal integrity analysis Included with the OrCAD PCB Designer is the Allegro Sigrity™ SI SigXplorer, which provides a graphical view of I/O buffers, transmission lines, and vias such that complex topologies can be modified in a what-if fashion without having to change the actual design. SigXplorer also allows engineers to sweep various parameters within the topology to identify a topology solution space. With the OrCAD PCB Designer Professional product, routed or unrouted topologies can be extracted directly from the PCB design database, enabling you to simulate critical nets to validate that the layout work matches the pre-route requirements. Topology extraction can be performed at three key stages for signal-quality prediction and analysis: during part placement (pre-route), after routing critical nets, and after final routing of the design. Topologies are extracted back into the SigXplorer canvas that was used to analyze the net during pre-route, and the routed signal's analysis is compared to the expected results. The extraction includes a detailed electrical representation of how the net was physically implemented, including models for trace cross-sectional characteristics, routing layers, via models, and trace lengths. If the results do not match, the routed board can be modified and the net re-analyzed.
