OrCAD PCB Designer Standard is a software package, which offers a very favorable entry into professional printed circuit board design with a price of 2.500 € (including 1 year maintenance). The PCB software already has the schematic entry module OrCAD Capture and OrCAD PCB Editor with integrated Constraint Manager. The scalable OrCAD / Allegro PCB platform provides investment protection for the user, as increasing technical requirements based on the same data base can be used to upgrade to more powerful Allegro licenses.OrCAD PCB Designer Standard includes the following functionality:
OrCAD Capture schematic entry tool for circuit diagrams is one of the world's most widely used software for entering and documenting electrical circuits. OrCAD Capture uses flat or hierarchical schematics. Via the navigation window the different pages of the schematic can be selected and thematically managed according to functional blocks. By using the integrated interface, it is also possible to use parts from Ultra Librarian and SamacSys, which offer millions of components. The electrical connections between the component pins can be established quickly and rules can already be defined on schematic level.
PCB Editor is the canvas to perform PCB layout. With many automated functions the designer can efficiently implement the physical design with traces, planes, component footprints, drill holes, etc. While working with automated assistance, design rule checks in real time help to follow design rules and implement the design intent ready for PCB production quickly. Interactively working in 2D and 3D offers advantages depending on the task.
The SPECCTRA auto router can help to complete the routing of a PCB with up to 6 signal layers. Selecting a net or a group of nets gives the user control, which nets are routed automatically. To influence the layout several parameters can be adjusted, such as fanout and routing direction. A router might not do the complete board, but when used wisely it supports the PCB designer to finish digital elements with constraints faster. Feasibility studies are done in minutes and give an indication, if the board is routable with this number of layers. Auto-interactive routing commands support the user in manipulation the automatically done routing.
OrCAD PCB Designer is based on Allegro PCB design technology and both (OrCAD and Allegro) use the same design database. The difference in the licenses is the feature set how to automatically edit and verify the design. The number of design rule checks varies by the type of license. The big advantage is, that you only pay for the functionality you need. When working in a team with multiple licenses, you can check out and use the license you need to perform a certain task or check. All information is stored in the same database.
During routing, the tool checks whether design rules are violated in real-time. When errors are caused, e.g. by placing a component in an unauthorized location, the tool will highlight a design rule violation. All rules defined in Constraint Manager can be checked. Unique for PCB layout tools are the more than 250 integrated DFM checks, which check against specifications of the PCB fabricator, assembly service provider or test facility, by automatically reading in their rules sets.
OrCAD PCB Designer Standard has already a fully integrated Constraint Manager in OrCAD Capture and OrCAD PCB Editor. It makes it easy to define design rules and assign topologies in a central place. The rules are hierarchically defined and can be assigned to a number of nets at the same time. With design rule sets as constraint sets (CSet), several rules can be summarized and reapplied in subsequent designs. OrCAD PCB Designer Standard can manage a variety of physical, spacing and DFM rules. During engineering review all the rules are visible in one view next to each other and wrong rules stand out.
Clicking on a net in the schematic can open the simulation for signal integrity. By changing the length or impedance, the signal quality can be analysed. IBIS models can be used for driver and receiver components when available, otherwise Cadence default models can be used with parameters from the datasheet.
Basic functionality of PSpice is integrated in the OrCAD PCB design flow. Design intend is entered in schematic entry tool OrCAD Capture and can be used to drive a PSpice simulation and develop functionality of the circuit. Same schematic can be used for documentation and simulation. The netlist can be created and the PCB Editor uses the schematic to cross probe during placement and routing. A comprehensive integration provides broad information and avoids errors in the design process.
