The latest release of Cadence Allegro and OrCAD printed circuit board (PCB) software offers new features and functionality designed to boost productivity and performance for PCB engineers. The Allegro and OrCAD PCB Design Release 16.3 includes the ability to miniaturize the footprint of end products and reduce the number of physical prototype iterations, making the design cycle more predictable. This release addresses increased functional and interconnect density through improvements for rigid-flex routing, extended high-density interconnect (HDI) rules, 3D viewing of PCBs and asymmetrical clearance for RF circuits. Extended micro via stacking rules allow users to create the most difficult HDI designs, and multi-line curved bus routing that hugs the flex outline accelerates the creation of rigid-flex designs. An integrated 3D PCB viewer gives visibility into components and HDI micro via breakouts. The Allegro PCB RF Option also helps speed the time to create accurate RF circuits through the use of asymmetrical clearances for one or more RF elements. Also featured in the 16.3 release are a number of significant productivity and usability improvements to the OrCAD family of products. OrCAD Capture CIS, for instance, now offers autowire capability to quickly add connections, as well as new 3D footprint viewing. OrCAD PCB Editor provides 3D viewing and flip-board design/editing and jumper support for single-sided PCB designs. OrCAD Signal Explorer has a revamped user interface, with drag-and-drop and copy-and-paste functionality, context-sensitive RMB functions and native IBIS model support. Usability improvements are another focus of the latest Allegro PCB Signal and Power Integrity software, which offers a new user interface and adds stack-up-aware capabilities to the pre-route analysis environment. Buffer modeling standards are embraced through native IBIS and SPICE support, including Cadence Virtuoso Spectre Circuit Simulator models. Another improvement that boosts design cycle management is the ability to quickly scan a PCB with dozens of multi-gigabit signals and quickly determine where detailed analysis should be applied as signals are ranked according to their signal-to-noise ratio. Other key issues addressed are associated with part data management. Integrated ECAD, MCAD part creation, generation and distribution reduce unnecessary physical prototype iterations. The new part introduction capability extends management, notification of pre-release and temporary parts to shrink the design cycle. In addition, engineers can implement part updates automatically based on approved, recommended replacements, ensuring quality of results through obsolete part tracking. The Allegro and OrCAD PCB Design Release 16.3 will be available for download by customers in early December 2009. Cadence, www.cadence.com. Self-paced Training Program

The 5.1.2 version of CXInsight is an integrated, one-stop product for project and product design data management in the electronics design and manufacturing industry. This release delivers added e-collaboration functionality including improved server-to-server connectivity, advanced bill of materials (BOM) merge capabilities, user-friendly tools and updated communication technology for the Internet. CXInsight 5.1.2’s tool set provides effective internal and external collaboration between project members across OEM and manufacturing sites through dynamic, real-time and secure e-collaboration effective communication (128 bit encrypted, binary compressed). Feedback is enabled through the firewalls between the design and manufacturing teams as well as all the other partners in the supply chain over the net. A seven-layer safety structure guarantees an secure collaboration environment based on a project room methodology. This latest release brings further connectivity capabilities in addition to client/server, CXInsight now supports full server-to-server connectivity for distributed PLM in the supply chain. Distributed PLM allows partners in the supply chain to be linked online to projects that they have been invited to by the project owner, creating a dynamic data chain between the different CXInsight servers, whereby the data is only in one location. Most members have restricted access rights to the project where they will find information that is only relevant to them, and different members can work concurrently on a particular project. An updated ODB++ (tgz) offers easier interface; BOM import allows full traceability and reuse of all content. A dedicated product data and manufacturing information management system is configured to work across all disciplines from design, engineering and assembly. As a manufacturing information management system, CXInsight 5.1.2 works down to the factory floor, distributing production files, with full version control, to the processes involved. This offers full product data management capability from which stable product data sets can be uploaded in the enterprise-wide formal PDM systems when required.

S-Parameter Support for SI Analysis
Support of S-Parameter based circuit models is available in the latest version of high-speed design and verification environment CR-5000 Lightning, revision 12.0. This extends the capabilities of SI simulation to include new application areas, and simplifies the process for layout engineers unfamiliar with S-Parameter based modeling. To analyze high-speed signals in applications featuring DDR2/3 or USB technology, accurate models for components such as common-mode filters, baluns, and connectors are required, and simple RLC models are no longer appropriate. Accurate simulation at frequencies into the multi-gigahertz range is required, using models that reveal the minimum amount of information about the internal component structure. S-Parameters suit this purpose, representing the transmission and reflection behavior of waves at specific frequencies, using industry-standard formats such as Touchstone, which has also been adopted by IBIS (I/O Buffer Information Specification). The signal integrity (SI) analysis within CR-5000 Lightning is performed by time-domain simulation that works in conjunction with design capture and physical layout. The frequency domain S-Parameter models are first transformed into compatible macro-models then imported into the simulation library. The transformation is only done once and the resulting model can be used for SI verification without the need for any detailed knowledge of the original S-Parameter set. The transformation tool provided by IdemWorks generates Zuken-specific, robust time domain macro-models quickly, taking care of sophisticated requirements such as model passivity and causality. It also provides port reduction to ensure fast and easy to use models that focus on real designer needs. Zuken and IdemWorks s.r.l., Italy, www.zuken.com/cr-5000-lightning.
