The OrCAD® 17.2-2016 release introduced new capabilities for OrCAD Capture, PSpice® Designer, and PCB Designer 17.2-2016 that address challenges with flex and rigid-flex design as well as mixed-signal simulation complexities in IoT, wearables, and wireless mobile devices. This latest release reduces PCB development time by addressing the need to design reliable circuits for smaller, more compact devices.
Please note all "in Maintenance" customer will receive their new 17.2 2016 license on Tuesday 10th May 2016
To enable a faster and more efficient flex and rigid-flex design creation critical to IoT, wearables and wireless devices, the OrCAD 17.2-2016 portfolio enables several new capabilities for flex and rigid flex design to minimize design iterations. Key flex and rigid flex features include:
- Stack-up by zone for flex and rigid-flex designs
- Inter-layer checks for rigid-flex designs
- Contour and arc-aware routing

In the OrCAD PCB Designer 17.2-2016 release, the Cross-Section Editor has been redesigned to leverage the underlying spreadsheet technology found in the Constraint Manager. It offers a one-stop shop for features that require the cross section for their setup, such as dynamic unused pad suppression and embedded component design. The Cross-Section Editor has been enhanced to support multiple stackups for rigid-flex design, each capable of supporting conductor and non-conductor layers such as Soldermask and Coverlay.

A new Padstack Editor has been introduced in OrCAD PCB Editor 17.2-2016 to ease padstack creation through a new modern user interface. In addition to supporting new pad geometries, drill types, additional attributes, and additional mask layers ability to define keep-outs within the padstack with complex geometries for all objects, the new capabilities allow PCB librarians to help PCB designers streamline the design process for complex padstacks, and also the commonly used padstacks.

The OrCAD PCB Designer 17.2-2016 release also include new features or enhancements targeted towards improving PCB editors’ productivity and ease-of-use. Other new features include: Via2via Line Fattening (HDI), Display Segments Over Voids, Layer Set Based Routing, Diff Pair Routing and DRC, Full Xnet Support, Gloss Commands, Contour Routing, and many more!

The Graphical Design Difference Viewer is a powerful, real-time, design difference, visual review utility in OrCAD Capture with the ability to perform logical as well as graphical comparisons on a page-by-page basis. The Graphical Design Difference Viewer generates an interactive single-report HTML file that is platform and tool independent, a unique viewing feature to identify the differences leading to changes in circuit behavior as well as differences based on individual object level, thereby helping address the specialized needs of the users.

With the newly introduced Advanced Annotation feature supported by OrCAD Capture, users can assign reference ranges hierarchically by automatically assigning values and perform annotation on the whole design, on hierarchy block at any level, page and property block, giving them complete control over their component annotation process in the design cycle.

The new virtual prototyping functionality introduced in PSpice helps electrical engineers overcome design challenges by automating the code generation for multi-level abstraction models written in C/C++ and SystemC. This functionality assists them in generating code requiring limited coding capabilities by design engineers and thereby making the process of virtual prototyping extremely convenient and easy.

Many improvements have been made to the backdrill process to assist PCB designers in managing the backdrill vias/padstacks, route around the backdrill vias/padstacks with accurate DRCs, and real-time feedback.
Tabbed routing
Tabbed routing is a new routing strategy in which trapezoidal shapes called tabs are added to parallel traces to control impedance in the pin-field/breakout region and crosstalk in open-field region. This method enables longer trace lengths and use of smaller trace spacing. Tabbed routing is used for impedance control and to manage crosstalk in critical signals, enhancing signal quality and improving route channel utilization.
