Cadence® SPECCTRA® for OrCAD® solves the challenges of complex interconnect
routing with powerful, automated technology. This robust, production-proven autorouter
includes a batch routing mode with extensive user-defined routing strategy control as
well as built-in automatic strategy capability. SPECCTRA for OrCAD achieves faster,
more efficient routing using algorithms that look at the design and draw from a library of
proven strategies based on the design’s content. It then configures and executes the
router as required.
An interactive routing environment, SPECCTRA for OrCAD features realtime interactive
trace pushing and shoving aids to make quick manual edits to traces. An interactive
placement environment with extensive floorplanning functionality and complete component
placement features eliminates the need to switch applications to make placement changes
to optimize routing. By using the auto-interactive floorplanning and placement capability
designers can improve routing quality and productivity, which are directly related to
component placement. The autorouter’s extensive rule set can control a wide range of
constraints from default board-level rules to rules by net /net class and regions.

SPECCTRA for OrCAD provides powerful, shape-based autorouting with fast, high completion rates. Its
routing algorithms are designed to handle a wide range of PCB interconnect challenges—from simple to
complex, low density to high density—as well as the demands of high-speed constraints.
The SPECCTRA for OrCAD route editor simplifies and streamlines the etch editing process. As new
conductors are routed, the plowing feature automatically pushes aside existing conductors and routes
around pins.
The placement editor allows designers to quickly place components while simultaneously evaluating space,
logic flow, and congestion before beginning the route or as needed during the routing process.
The PCB routing technologies are tightly integrated with the PCB editor. Through the PCB editor interface,
all design information and constraints are automatically passed to the router. Once the route is completed,
all route information is automatically passed back to the PCB editor.
