The Cadence® OrCAD® PCB Designer Basics suite contains everything needed for
schematic capture with a fully integrated design flow. A common database architecture,
use model and library offer fully scalable PCB solutions for both OrCAD and Cadence
Allegro® product lines, giving you the ability to grow and expand as designs and design
challenges increase in complexity. The results are increased productivity, shorter design
cycles, and faster ramp up to volume production.

-
Cadence OrCAD Capture, a comprehensive solution for entering, modifying, and verifying complex system designs quickly and cost-effectively
- Cadence OrCAD PCB Editor Basics, based on Allegro technology: an intuitive, easy-to-use, constraint-
driven environment for creating and editing PCBs
OrCAD PCB Designer with PSpice® includes all of the above plus:

OrCAD Capture offers a comprehensive solution for entering, modifying, and verifying complex system
designs quickly and cost-effectively. Whether used to design a new analog circuit, revise a schematic
diagram for an existing PCB, or design a digital block diagram with an HDL module, OrCAD Capture
allows designers to enter, modify, and verify the PCB design.
SCHEMATIC EDITING
The full-featured schematic editor enables users to place and connect parts from a comprehensive set of
functional libraries. It uniquely packages the parts, ensures design integrity, and creates design netlists for
any of the formats supported by Cadence.
PROJECT MANAGEMENT
The project manager enables users to collect and organize all the resources needed for the project
throughout the design flow. The expanding tree structure makes it easy to organize and navigate
design files, including those generated by PSpice and Cadence Allegro AMS Simulators, Cadence
OrCAD Capture CIS, Cadence Allegro Design Entry CIS, and other plugins.
HIERARCHICAL DESIGN AND REUSE
OrCAD Capture boosts schematic editing efficiency by enabling subcircuit reuse—without having to
make multiple copies. Using hierarchical blocks, designers simply reference the same subcircuit
multiple times. Automatic creation of hierarchical ports eliminates potential design connection errors.
LIBRARIES AND PART EDITING
The library editor is accessed directly from the user interface. Users can create and edit parts in the library
or directly from the schematic page without interrupting workflow. Intuitive graphical controls speed
schematic part creation and editing. New parts can be created quickly by modifying existing ones.
EASY DATA ENTRY
Designers can access all part, net, pin, and title block properties or any subset and make changes quickly
through the spreadsheet property editor.
NOTE: The OrCAD Capture product in the PCB Designer Basics suite has the following capability
limitations for creating a PCB Editor netlist:
- PCB Editor Basics netlists are limited to a design containing less than 500 components and/or 2000 nets.
- The PCB Editor netlister is the only netlister available with this suite.
- High-speed signal flow properties such as PROPAGATION_DELAY,
RELATIVE_PROPAGATION_DELAY, RATSNEST_SCHEDULE and DIFFERENTIAL_PAIR in your
design are not transferred to the PCB Editor board.

PCB EDITING ENVIRONMENT
At the heart of the OrCAD PCB Designer Suite is OrCAD PCB Editor—an intuitive, easy-to-use, constraint-
driven environment for creating and editing simple to complex PCBs. Its extensive feature set addresses a
wide range of today’s design and manufacturability challenges. The PCB editor provides a powerful and
flexible set of floorplanning tools. Powerful shape-based shove/hug interactive etch creation/editing provides
a highly productive interconnect environment. Dynamic shape capability offers real-time copper pour
plowing/healing functionality during placement and routing iterations. The PCB editor can also generate a
full suite of phototooling, bare-board fabrication and test outputs, including Gerber 274x, NC drill, and bare-
board test in a variety of formats.
CONSTRAINT MANAGEMENT
A constraint management system displays physical and spacing rules. Each worksheet provides a
spreadsheet interface that enables the user to define, manage, and validate the different rules in a
hierarchical fashion. This powerful application allows designers to graphically create, edit, and review
constraint sets as graphical topologies that act as electronic blueprints of an ideal implementation strategy.
Once the constraints are present in the database, they are used to drive the placement and routing processes
for constrained signals. The constraint management system is completely integrated with the PCB editor.
FLOORPLANNING AND PLACEMENT
The constraint and rules-driven methodology drives a powerful and flexible set of placement capabilities,
including interactive and automatic component placement. The engineer or designer can assign components
or subcircuits to specific “rooms” during design entry or floorplanning. Components can be filtered and
selected by reference designator, device package/footprint style, associated net name, part number, or the
schematic sheet/page number. With thousands of components on today’s boards needing precise
management, real-time assembly analysis and feedback increases the designer’s productivity and efficiency
by placing components to corporate or EMS guidelines.
INTERACTIVE ETCH EDITING
The interactive routing capability of the PCB editor provides powerful, interactive features that deliver controlled
automation to maintain user control, while maximizing routing productivity. Real-time, shape-based, any
angle, push/shove routing enables users to choose between “shove-preferred,” “hug-preferred,” or “hug-only”
modes. Shove-preferred mode allows users to construct the optimum interconnect path while the real-time,
shape-based router takes care of dynamically pushing obstacles. Routes will automatically jump over
obstacles such as pins or vias. The hug-preferred mode is the perfect solution when a databus needs to be
constructed. In hug-preferred mode, the router contour follows other interconnect as a priority and only pushes
aside or jumps obstacles when there is no other option. The hug-only option performs like the hug-preferred
mode, but without the push-and-shove aggression on other etch objects. The real-time, embedded, shape-
based routing engine optimizes the route by either pushing obstacles or contour-following obstacles while
dynamically jumping vias or component pins.
DYNAMIC SHAPES
Dynamic shape technology offers real-time copper pour plowing/healing functionality. Shape parameters can
be applied at three different levels. Parameters are structured into 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 will automatically fill back in. Dynamic shapes do not
require batch autovoiding or other post-processing steps after edits are made.
PCB MANUFACTURING
A full suite of photo-tooling, bare-board fabrication and test outputs, including Gerber 274x, NC drill, and
bare-board test in a variety of formats can be generated. More importantly, OrCAD PCB Editor supports the
industry initiative towards Gerber-less manufacturing through its Valor ODB++ interface that also includes
the Valor Universal Viewer. The ODB++ data format creates accurate and reliable manufacturing data for
high-quality, Gerber-less manufacturing.
