  • CAD/CAM/PCB Software Providers

  • Cadence Upgrades OrCAD PCB CAD

    OrCAD PCB CAD software now includes five new products and three key features aimed at increasing productivity by reducing design cycle time and facilitating more advance designs via additional high-speed capabilities.

    OrCAD Component Information Portal provides users with CIS database management capabilities and integrated access to parametric component data through an interactive, web interface directly within the OrCAD Capture CIS product.

    OrCAD DFM Checker provides a comprehensive set of manufacturing/fabrication-centric checks for OrCAD PCB Editor. DfM fabrication checks can be run at any time during PCB place and route to help ensure that no fabrication-related issues are present, helping avoid fabrication-related delays, additional costs and re-work.

    OrCAD Panel Editor provides an intelligent panel documentation environment for OrCAD PCB Editor that significantly simplifies panel creation and documentation.

    OrCAD Sigrity ERC (Electrical Rules Check) provides a comprehensive set of electrical signal quality checks for OrCAD PCB Editor. ERCs are designed to be run by the PCB designer as a first-order electrical validation. This capability enables changes to be made within the design before more extensive and exhaustive analysis is performed.

    OrCAD Capture Constraint System enables a constraint-driven PCB design flow for OrCAD Capture and OrCAD PCB Editor. Compared to the existing methodology, the OrCAD Capture Constraint System substantially expands the constraint definition and management methodology in OrCAD Capture.

    New technologies include:

    OrCAD PCB Editor productivity improvements include Scribble Route, an auto/interactive routing feature, which allows the user to loosely sketch a path for a route as the system figures how to detail-route it, as well as group and contour routing updates and via arrays.

    OrCAD PCB Professional high-speed design features now offer enhanced differential pair constraints, propagation constraint support, delay tuning with heads-up display support, net scheduling and impedance constraint support.

    OrCAD Signal Explorer is being added to OrCAD Capture technology-based products, enabling front-end signal integrity/signal quality simulation as well as topology exploration and constraint definition. It can also be scaled for additional signal exploration and signal integrity capabilities through OrCAD PCB SI.

Users can apply multiple variable chamfers in a single operation and directly change fillets into chamfers. Can access previous hole definitions, apply pre-saved specifications, and construct stepped holes faster than in previous versions. Can create 3D geometry and surface characteristics using new surfacing features, including wrap, drag and drop, emboss, deboss, and 3D curve. A magnetic mates feature organizes assemblies by setting up connection points for drag-and-drop mating and repositioning. Suggests alternate designs. Analysis and automatic design alterations are communicated in the RealView bar. Integrates Altium electronic design software.

  • Data-Driven Manufacturing

    Scott Fillebrown

    The right data package will speed assembly and test programming.

  • Design Practices for Panelization and Depanelization

    Assemblers demand a complete CAD data package for more effective manufacturing.

    Panelization, also known as the processing of boards in an array format, keeps small boards attached to each other within a single, larger substrate. Panelization is used to process multiple small boards through assembly, and is becoming more prevalent as board sizes shrink.

  • DownStream Updates BluePrint-PCB 5.1 Documentation Software

    BluePrint-PCB 5.1 has a new graphic user interface that aligns with Microsoft Ribbons user interface scheme. Ribbons interface flattens menu hierarchy to make access to common functions faster. Has a new “world view” to give users quick reference to current screen location. An optional pan-and-zoom function aligns viewing functions with most printed circuit board CAD tools; uses middle mouse button to zoom in and out of sheet-sized documents. Panning function quickly pans across drawing sheet while viewing or executing other drawing commands. User interface enhancements borrow design cues from SoloPCB design tools. Modifications were made to assembly panel functions. When panel design is executed, document view is replaced by a design view that allows color-coding of different panel objects. Assembly panel toolkit now features smart callouts that automatically detect pinning holes and board chamfer; automatically calculates number of instances these features are used in the design to minimize PCB fabrication errors. New online mill checking features have been added. DFMStream has been updated to include new analysis checks to verify anti-pads to adjacent layers to validate 100% ground plane reference and same net minimal spacing. Negative planes were expanded to include minimal width and gap between copper elements and anti-pads. Analysis functions have been upgraded to provide more options to manage the user workspace.

  • Is ‘Free’ Worth It?

    Mike Buetow

    There’s only so much a company can give away without extracting payment of some kind. Perhaps the world’s biggest provider of free stuff, Google, “gives away” its search tools, but in exchange users are offered less than democratic responses whereby the highest ranked terms are paid for. And in fact, the cost of “free” search is underwritten by copious amounts of advertising.

  • Mentor Announces Extensions to Pads PCB CAD

    Pads PCB CAD platform features new analog/mixed-signal (AMS) and high-speed analysis tools for mixed-signal design, DDR implementation, and electrically correct design signoff. 

    Features: 

      • Pads AMS Cloud,a cloud-based circuit exploration/simulation environment and user community, addresses analog/mixed signal simulation. Users from all levels of expertise can create and share analog, mixed-signal, and mixed-technology designs in an online, collaborative environment where designs and models can be published or downloaded. Circuit designs created in AMS Cloud can be transferred to the AMS Design Suite desktop environment, eliminating the need to manually recreate circuits to perform advanced analysis and drive the PCB design flow.
      • Pads AMS Design Suite, which allows design and simulation of analog/mixed-signal and digital in one environment. Within one schematic session, both analog circuit simulation leveraging VHDL-AMS, and topology exploration with the HyperLynx tool can be performed. Beyond common core AMS simulation analysis (DC Bias, time-domain, and frequency-domain simulations) additional extended analysis capabilities are included as standard, such as multi-run parametric sweeps, sensitivity, Monte Carlo, and Worst Case analysis to address specific engineering needs.
      • Pads HyperLynx DDR option, for integrated DDR simulation, which identifies and solves signal integrity (SI) and timing issues specific to DDRx designs.
      • Pads HyperLynx DRC tool, which accelerates electrical sign-off process by allowing electrical rules checks and identifying violations that will affect the design integrity and performance of the board. With predefined rules, reportedly quickly identifies issues such as traces crossing voids and traces changing reference planes on large designs. Integrated electrical DRC technology demonstrates PCB designs are electrically correct before hand-off to manufacturing. Key capabilities: Fast and easy time to results with a rules-based approach to identify non-CAD constraints; out-of-the-box checks for EMI, signal integrity and power integrity; easy identification of violations integrated with the PADS PCB product.
