New Cadence Allegro Enhances Flex and Rigid-Flex Capabilities
May 4, 2016 | Cadence Design Systems, Inc.Estimated reading time: 3 minutes

Cadence Design Systems has unveiled the Allegro 17.2-2016 portfolio, which enables a more predictable and shorter design cycle. The portfolio features comprehensive in-design inter-layer checking technology that minimizes design-check-redesign iterations and a new dynamic concurrent team design capability that accelerates product creation time by up to 50 percent. Utilizing material inlay fabrication techniques, these new capabilities can reduce material costs by up to 25 percent. In addition, embedded Sigrity technology now ensures critical signals meet performance criteria and power integrity (PI) for PCB designers addressing power delivery and IR-drop issues efficiently, eliminating time-consuming iterations with PI experts.
The Allegro portfolio includes key advancements that minimize design iterations and lower overall cost for flex and rigid-flex designs commonly used in automotive, consumer electronics, computing, communications, mobile and wearable applications. These capabilities include:
- Rigid-Flex design enhancements that give designers the ability to specify multiple rigid and flex stack-ups in the same database. This stack-up-by-zone feature can also be used in rigid designs to create material inlay regions leveraging a mix of expensive and inexpensive materials, enabling reduction of material cost by up to 25 percent.
- Unique and comprehensive in-design inter-layer checks for flex and rigid-flex that saves manual effort and ensures all rules for advance flex designs are adhered to, avoiding many design-check-redesign iterations.
- PI for PCB designers that leverages Allegro and Sigrity technologies to provide faster, more reliable access to IR-drop analysis results, enabling PCB designers to efficiently meet power delivery network (PDN) design requirements.
- Interoperable Allegro and Sigrity technologies that provide an easy to use environment, which shortens design and verification time. This is achieved by avoiding unnecessary physical prototype iterations through improved route channel utilization using tabbed routing, new in-design backdrilling rules and efficient sharing of custom return path via structures optimized with Sigrity technology.
- New Native 3D engine that streamlines the system design process and provides improved visualization and collision detection to avoid unnecessary MCAD/ECAD iterations.
The Allegro portfolio now provides synchronous team design capability, which can shorten design time by up to 50 percent for dense designs and increase efficiency by enabling the team to design synchronously. This feature enables PCB designers to achieve maximum productivity by allowing up to five PCB designers to conduct real-time, concurrent PCB design work within the same design database, shortening time to route a dense design by up to 80 percent.
"Due to the nature of our business, flex designs are extremely critical to many of our products, specifically in the mobile and automotive space. The breadth and the depth of enhancements have the ability to significantly improve our PCB design productivity in designing for space-constrained applications," said Greg Bodi, director of System Engineering PCB Layout, Nvidia. "The new inter-layer check capability provides comprehensive in-design, real-time checks, which will save us significant time currently spent doing manual checks after layout is completed on advance flex and rigid-flex designs."
"The latest Allegro release provides many productivity and ease of use improvements," said Dave Elder, PCB Engineering manager at Tait Communications. "In-design inter-layer checks for flex and rigid-flex design is comprehensive and extensible, which can save us 20 to 25 percent time for rigid-flex designs. This will also allow us to retire some homegrown solutions we put in place."
"The new Allegro platform addresses many challenges faced by PCB designers on a daily basis," said Saugat Sen, vice president of R&D, PCB and IC Packaging Group at Cadence. "We continue to provide market-leading solutions with Allegro's extensive Rigid/Flex capabilities coupled with industry-leading power aware Sigrity SI/PI technology to reduce design cycle time for our customers' compact, high-performance products."

Elementary Mr. Watson: Retro Routers vs. Modern Boards—The Silent Struggle on Your Screen
06/26/2025 | John Watson -- Column: Elementary, Mr. WatsonThere's a story about a young woman preparing a holiday ham. Before putting it in the pan, she cuts off the ends. When asked why, she shrugs and says, "That's how my mom always did it." She asks her mother, who gives the same answer. Eventually, the question reaches Grandma, who laughs and says, "Oh, I only cut the ends off because my pan was too small." This story is a powerful analogy for how many PCB designers approach routing today.

Cadence AI Autorouter May Transform the Landscape
06/19/2025 | Andy Shaughnessy, Design007 MagazinePatrick Davis, product management director with Cadence Design Systems, discusses advancements in autorouting technology, including AI. He emphasizes a holistic approach that enhances placement and power distribution before routing. He points out that younger engineers seem more likely to embrace autorouting, while the veteran designers are still wary of giving up too much control. Will AI help autorouters finally gain industry-wide acceptance?
Beyond Design: The Metamorphosis of the PCB Router
06/18/2025 | Barry Olney -- Column: Beyond DesignThe traditional PCB design process is often time-consuming and labor-intensive. Routing a complex PCB layout can consume up to 30% of a designer’s time, and addressing this issue is not straightforward. We have all encountered this scenario: You spend hours setting the constraints and finally hit the Go button, only to be surprised by the lack of visual appeal and the obvious flaws in the result.
