New capabilities for flex and rigid-flex designs
- Stack-Up by Zone for Flex and Rigid-Flex Designs: Multiple zones can be created using the new Cross-Section Editor to represent rigid-flex-rigid PCBs. The stack-up by zone feature provides faster, easier definition of stack ups for rigid-flex-rigid designs and improves MCAD-ECAD co-design.
- Inter-Layer Checks for Rigid-Flex Design: The Allegro PCB Editor 17.2-2016 release introduces new in-design inter-layer checks for flex and rigid-flex that save manual effort and ensure all rules for advance flex designs are adhered to, avoiding many design-check-redesign iterations.
- Enhanced Contour, Arc-Aware Routing: Enhanced Contour is a more efficient method to add routing during Add Connect by following an existing connect line or a route keep-in, which will save time for PCB designers working on flex designs.
The Cross-Section Editor has been redesigned, leveraging the underlying spreadsheet technology found in Constraint Manager. It offers one-stop shop for features that require the cross section for their setup, such as dynamic unused pad suppression and embedded component design.
Dynamic concurrent team design
The New Allegro dynamic concurrent-team-design capability focuses on shortening the largest portion of the PCB layout design cycle. It provides dynamic concurrent PCB team design for multiple PCB designers to work on the same design at the same time without any set-up requirements. In addition, new features—including interactive etch-editing capabilities, Allegro TimingVision™ technology, auto-interactive delay, and phase-tuning capabilities—provide proven time reductions to route advanced high-speed interfaces such as DDRx and PCI Express® (PCIe®) by up to 80 percent.
New Padstack Editor
A new Padstack Editor eases padstack creation through a new modern user interface. New features include the padstack designer, padstack usage types, pad geometries, and several new drill features.
Expanded in-design rules for backdrill vias
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 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
Return path management through custom via structures
The Allegro 17.2-2016 release enhances the six via structures for managing return paths for critical differential signals during Add Connect by allowing users to create using Allegro PCB Editor, validate using proven Sigrity technology, and instantiate a custom return path via structure during Add Connect.
Ease-of-use improvements in Allegro PCB Editor
- Visibility Pane—Access to Mask Layers and Zones: The Visibility Pane has been enhanced to allow designers access and control of layer content more quickly and more efficiently.
- Shape Edit Application Mode: The Shape Edit Application Mode is a tuned editing environment primarily designed to increase efficiency with shape boundary editing.
- Constraint Manager Improvements: Many ease-of-use and productivity improvements have been made to Allegro Constraint Manager.
