OrCAD Layout incorporates a spreadsheet-based constraint management system thatgives designers easy access to board rules.Powerful floorplanning and advanced place-ment functionality provides greater controlover component placement. Auto-interactiverouting is ideal for hand-routed designs. Thedesign rule checking (DRC) route engine easi-ly pushes and shoves vias and traces, avoid-ing routing obstacles. Intelligent copper poursupports mixed-voltage power planes. Bothbatch DRC and online DRC are available.Online DRC checking can be toggled on or off and works in conjunction with the auto-interactive router. Additionally, you can choosefrom standard reports or create customizedreports to suite your individual needs. Intuitivepost-processing tools with an output previewprovide quick and error-free output. OrCADLayout is ideal for individuals and small tomedium design teams creating printed circuitboards from prototype to production.

INTEGRATION WITH ORCAD CAPTURE AND CAPTURE CIS SCHEMATIC TOOLS

Component properties, pin properties, and netproperties can be assigned in OrCAD Capture®

or OrCAD Capture CIS and then passed toOrCAD Layout. Inter-tool communication sup-ports cross-probing of components and netsbetween OrCAD Capture and OrCAD Layout.You can specify spacing rules, flag criticalnets, and specify other key design constraintson the schematic and pass that information toOrCAD Layout. AutoECO forward annotates allchanges made in the schematic to the boardwhile back annotation performs a full databasecomparison and creates a back annotation filecontaining changes made in the board data-base to the schematic. Bi-directional propertypassing allows board-level design rules to bepassed back and forth.

INTER-TOOL COMMUNICATION STREAMLINESTHE ENTIRE BOARD DESIGN PROCESS

Many problems in PCB design can be traced toincorrect component information or poor commu-nication between engineers and board designers.Specifying an obsolete component or one that hasan unexpectedly long lead time can result inexpensive rework. Even a simple communicationerror can trigger an extra board turn and delay aproject significantly. This can happen, for exam-ple, when a designer changes an IC package orthe wattage of a resistor without changing thecorresponding PCB footprint and company partnumber. Such errors are easy to miss, especiallywhen design teams communicate via email mes-sages and handwritten notes. If discovered earlyin the design process, these errors can be easilyavoided. If discovered after the board has beenfabricated, assembled, or shipped in a productthese problems are far more expensive to correct.Through the CIS Option for OrCAD Capture andits tight integration with OrCAD Layout, you caneliminate these types of errors. You start theboard design process with up-to-date and reliablecomponent information, enabling you more cor-rect first-pass designs that will streamline yourprocess to meet critical product release windows.

AUTOMATIC ECO AND BACK ANNOTATION

When you implement changes to connectivity,component information, or design constraints inthe schematic, the AutoECO feature detects thechange and processes it as an ECO. OrCADLayout also passes changes in reference designa-tors, pin, and gate swaps, along with physicalcomponent placement information, back to theschematic.

COMPONENT PLACEMENT

Components can be grouped into clusters basedon connectivity. These “super components” allowyou to work with fewer objects, providing a highlevel view of the overall placement strategy.Component grouping makes it easy to move components as a single object, simplifying thecreation of identical circuits. Group assignmentcan be done at the schematic or board level.Components can be dropped into a heavily popu-lated area of the board and the “auto-shove”functionality automatically shoves other compo-nents out of the way to make room. This is donewith full DRC control. Component locking/fixingtemporarily or permanently prohibits componentsfrom being moved. Component locations speci-fied from within OrCAD Capture or OrCADCapture CIS can be imported. Keep-in and keep-out areas can be defined by component group orby height for floorplanning. Complete mechanicalinformation, including all necessary floorplanningconstraints from systems such as Pro/ENGINEERand SDRC I-DEAS, can also be imported.

MANUAL ROUTING/EDITING

T-routing allows you start or stop routing on apad, via, or track segment. Track width can bequickly changed on-the-fly during the routingprocess. Segment editing allows you to slide seg-ments, under DRC control, quickly pushing seg-ments together to maximize available board realestate. Sliding segments will jump over obstaclesto valid locations. Segment splitting divides anexisting segment into two segments or easiermanipulation. Complete tracks can be moved toanother layer under DRC control.

AUTO-INTERACTIVE ROUTING

Interactive routing in OrCAD Layout offers power-ful functionality and user interactive features. Useauto-path mode to select individual connectionsand steer a route interactively, with automaticshoving and clearing of surrounding tracks. Useauto-completion mode to steer a partial route,then let the autorouter complete it for you.Activate push/shove routing to steer routes inter-actively through congested areas as the routerclears a routing path, while observing DRCrequirements.

GRID-BASED AUTOROUTER

The autorouter in OrCAD Layout is especially useful when boards consist of similar-pitch components. The built-in, 16-layer, grid-basedautorouter with push/shove capability, routes simple designs quickly with high-speed and highcompletion rates. Push/shove technology mini-mizes vias and allows higher routing density. It finds the optimal route for a track and then modifies existing routes and vias to clear spacewhile adhering to all design rules.

AUTOMATIC FANOUT

An increasing number of designs today call forBGA and micro-BGA packages. OrCAD Layoutautomatically creates the complex interconnectthese devices require. Fanouts can also be creat-ed for individual components or for an entireboard. Users have control over the fanout dis-tances, the ability to share/not share fanout vias,and control of fanout direction, either inside oroutside of a component.

SPECCTRA INTERFACE

The SPECCTRA® for OrCAD autorouter interface isembedded in the autorouting selections of OrCADLayout, providing a seamless interface to theautorouter. The interface allows users to easilymove PCB data and constraints to and from theSPECCTRA autorouter. SPECCTRA for OrCAD istightly coupled with OrCAD PCB Editor, providinga rapid and seamless path for design autorouting.Routing strategy and setup is performed directlyinside OrCAD PCB Editor using router setupdialogs. The interface then takes the defined rout-ing setup, strategy, and all the design rules, andexecutes the router in a batch mode. The router’sprogress can be tracked interactively from withinOrCAD PCB Editor. Once the routing strategy iscompleted, the routed interconnect is automatic-ally imported back into OrCAD PCB Editor.Routing functions can be performed on a singlenet, a group of nets, or the whole design, allow-ing for the maximum in routing flexibility.

COPPER POUR, POWER PLANES,AND COPPER AREAS

Intelligent copper pour fully supports split-powerand ground planes. Connections to the copperpour will only be created if the voltages of the pinand copper match. Copper pours can be overlaidand controlled with a Z-order rule which specifiesthe pouring order of the individual copper pours;the highest Z-order is poured last, leaving clear-ance between itself and the previous copper pour.Connectivity is automatically updated throughcopper pour, power planes, tracks, copper areas,and “free tracks.” Pads and vias can be designat-ed as flood fill for direct hit on planes in high-cur-rent designs.

ERROR CHECKING

Online DRC for routing and placement can be toggled on and off at any time. Double-clicking inthe error-marker spreadsheet zooms to the errorin the board window. Also, clicking on error coor-dinates in the query window automatically zoomsto that error in the board window.

Online DRC works in conjunction with the interac-tive routing commands. Routing with ‘Allow DRCError’ enabled can speedup manual routingthroughput. If a DRC error is detected, you getreal-time error notification.

REPORTS AND POST-PROCESSING

OrCAD Layout has an extensive report list andoutputs customized reports. Reports can be savedas files and/or viewed directly on screen. Designpost processing can be directed to a printer, or toGerber or DXF files. All output settings are storedin a spreadsheet that can be saved and revised.This allows you to preview and select the properoutput for each layer before creating the actualoutput files. OrCAD Layout also produces morethan 20 standard reports including fabricationdrawings, assembly drawings, and pick-and-placereports. Reports can also be created and cus-tomized for individual needs. A built-in output pre-view provides the user with the ability to examinethe output before the actual files are created.

INDUSTRY INTERFACES AND OUTPUT
