New Cadence Allegro DesignTrue DFM Technology Accelerates New Product Development and Introduction Process

Cadence Design Systems, Inc. today announced Cadence Allegro DesignTrue DFM technology, the industry’s first solution to perform real-time, in-design design-for-manufacturing (DFM) checks integrated with electrical, physical and spacing design rule checks (DRCs). The innovative new technology, integrated into the Allegro PCB Editor, enables PCB designers to identify and correct errors immediately, long before manufacturing signoff. By finding errors earlier, design teams reduce rework, shorten design cycles and accelerate the new product development and introduction process, potentially saving at least one day per iteration and days to weeks overall.
Unlike manufacturing signoff tools that are run in batch mode when performing DFM checks, Allegro DesignTrue DFM technology provides continuous in-design feedback while designing, eliminating the frustrating and time-consuming design-verify-fix iterations between PCB designers and DFM checking teams. By the time PCB designers reach final DFM signoff, they already know their design meets manufacturing rules, resulting in a smoother signoff and handoff to the manufacturing partner and a shorter, more predictable design cycle.
Allegro DesignTrue DFM technology is consistent with the proven Allegro constraint-driven design flow and online checking solution currently used for electrical, physical and spacing rules. Allegro DesignTrue technology provides a wide set of checks to ensure design manufacturability. Spacing between copper features such as traces, pins, vias relative to the board outline and other copper features can be verified in real time, independent of electrical and net-based rules.
The new technology makes it easy to configure, apply contextually and reuse manufacturing rules. Allegro DesignTrue DFM technology supports the import and export of DFM rules and addresses more than 2,000 advanced checks. In addition, it employs a new and more user-friendly DRC browser capable of addressing one class of errors at a time. Constraints are highly configurable with the ability to enable and disable groups and whole categories of rules, or individual rules. Rules can be applied in etch mode, non-etch mode, and in stack-up mode, giving designers the ability to isolate layers, geometries and cutouts. The new browser also features an integrated DRC description with graphics, characterizes DRCs by type and provides a DRC count chart. Users can quickly sort, browse and review, as well as waive and unwaive DRCs.
“Increasing PCB complexity is extending our design cycles and making them unpredictable,” said Greg Bodi, director of System Engineering PCB Layout at NVIDIA. “With Allegro DesignTrue DFM technology, our PCB design teams can be sure that they are designing the board correctly the first time, taking into account electrical, physical and manufacturing constraints. This eliminates unnecessary iterations with manufacturing signoff processes and saves us days to weeks of time.”
“Accelerating new product development and introduction is a key priority for our customers,” said Tom Beckley, senior vice president and general manager, Custom IC & PCB Group. “For more than 15 years, our customers have relied on the Allegro constraint-driven flow and online checking solution for the electrical and physical domains. As part of our System Design Enablement strategy, we’re now applying this same approach to DFM checks. Extending our solution to the manufacturing domain enables electronics OEMs to bring their products to market more quickly and with greater confidence.”

Global PCB Connections: Following DFM Rules Leads to Better Boards
12/18/2024 | Jerome Larez -- Column: Global PCB ConnectionsAs a PCB field applications engineer, ensuring smooth communication between PCB designers and fabricators is one of my frequent challenges. A critical part of that dialogue is design for manufacturing (DFM). Many designers, even experienced ones, often misunderstand or overlook important DFM considerations. They may confuse design rules with manufacturing minimums, leading to technically feasible designs that are difficult or costly to produce. In this column, I will clarify some common DFM guidelines and help designers understand the difference between “design rules” and “minimums” while sharing best practices that will simplify the production process and ensure the highest quality PCB.
Sayonara to the Last Standing Copper Foil Plant in North America
12/17/2024 | Marcy LaRont, I-Connect007In July 2021, PCB007 Magazine published an interview with Michael Coll and Chris Stevens of Nippon Denkai about the new acquisition by Nippon Denkai of the last-standing ED foil manufacturer in North America. The plant in Augusta, Georgia, was formerly owned by Oak Mitsui, Inc. and had been purchased by Nippon Denkai the previous March, after which significant investment was made with the expectation of providing more jobs.

Fresh PCB Concepts: PCB Plating Process Overview
12/12/2024 | Team NCAB -- Column: Fresh PCB ConceptsIn this installment of Fresh PCB Concepts, Mike Marshall takes the helm stating: PCBs have been the platform for the interconnection of electronic components for decades. Because of process costs and other constraints, such as mechanical properties or size limitations of the alternatives, PCBs will remain the standard low-cost interconnection technology. Rapidly increasing performance and functionality requirements of wireless and high-speed devices have challenged the development and implementation of new manufacturing solutions.
