Allegro 如何保证设计一次成功

Late-stage design changes are incredibly costly. The later the change, the more rework is required, and the more expensive the project becomes. So naturally, you want to find those errors as soon as possible. But here’s the thing, no matter how early you find that error, you’ve still made an error.

Finding mistakes, fixing mistakes; you’re missing the point.

Don’t make mistakes.

Make It Work: Allegro Vision and Analysis Technology

It takes creativity to solve the complex design challenges of cramming more components and more traces in a smaller space. Even if everything fits, the biggest question is “will it work?” The unique Cadence^® Allegro^® vision and analysis technology, driven by our proven constraint-driven design flow, makes it easy for designers of all skill levels and experience to improve design quality in your high-speed, high-density designs.

Visual indicators and automatic channel optimizations help designers place traces and components perfectly for optimal performance, without needing any off-sheet calculations.

Performance insights are more complex than manufacturing constraints. The Allegro vision and analysis technology shows designers how placement impacts propagation, timing, and delay constraints, something a simple distance-based manufacturing check can’t do.

Ultimately, the biggest challenges designers face are signal integrity issues. The integrated analysis technology helps designers avoid return path and impedance issues, coupling and crosstalk issues, and more, visually, by highlighting problematic traces in real time while designing; without sending the board off to an SI expert, and without having to wait for results.

Make It Fit: Interactive 3D

The thing you’re designing is not 2D. A final PCB exists in the real world in all three dimensions, and you need to think three-dimensionally when you’re designing.

View the enclosure and other mechanical elements of the final product in your PCB design environment and verify fit in the interactive 3D canvas, without going back and forth with the mechanical designer. Mechanical engineers and PCB designers can push and pull changes between Allegro PCB Editor and the mechanical design environment.

Get placement of all your components just right by moving things around in the interactive 3D canvas or move them in 2D and see the update in 3D, side by side in real time. Automated collision checks can even show issues that you can’t see from any angle.

Make It: Allegro PCB DesignTrue DFM Technology

Manufacturing is the last step of the design process. But manufacturability problems in the design can only be fixed by going back and re-designing. Leave manufacturability checks to the end, and you’ll have to start your design all over when you find a problem.

Allegro PCB DesignTrue DFM Technology applies your manufacturing, fabrication, test, and assembly rules before you start designing so that every route and every component placement is verified against your unique rules.

Visual error markers flag copper and non-copper feature-related fabrication, assembly, and test issues so designers can correct them in real time without cascading consequences to the design later.

后期设计更改成本极高。变化越晚，需要返工越多，项目就越贵。因此，您自然希望尽快发现这些错误。但事情是这样的，无论你发现那个错误有多早，你仍然犯了一个错误。

发现错误，纠正错误；你没有抓住重点。

不要犯错。

让它发挥作用：快板视觉和分析技术

解决在较小空间中填塞更多组件和更多痕迹的复杂设计挑战需要创造力。即使一切都合适，最大的问题是“有用吗？”独特的Cadence^® Allegro^®视觉和分析技术，由我们经过验证的约束驱动的设计流程驱动，使所有技能水平和经验的设计师都能轻松提高高速、高密度设计的设计质量。

视觉指示器和自动通道优化有助于设计师完美放置跟踪和组件，以获得最佳性能，而无需任何表外计算。

性能洞察力比制造约束更复杂。Allegro视觉和分析技术向设计师展示了放置如何影响传播、定时和延迟约束，而简单的基于距离的制造检查是无法做到的。

归根结底，设计师面临的最大挑战是信号完整性问题。集成分析技术通过在设计时实时突出显示有问题的痕迹，而不是将板发送给SI专家，也不必等待结果，帮助设计师在视觉上避免返回路径和阻抗问题、耦合和串扰问题。

让它合身：交互式3D

您正在设计的东西不是2D。最终的PCB存在于现实世界中的所有三维空间，您在设计时需要进行三维思考。

在PCB设计环境中查看最终产品的外壳和其他机械元素，并验证交互式3D画布的贴合度，而无需与机械设计师来回走动。机械工程师和PCB设计师可以在Allegro PCB编辑器和机械设计环境之间推动和拉动变化。

通过在交互式3D画布中移动东西或以2D移动它们来正确放置所有组件，并实时以3D并排查看更新。自动碰撞检查甚至可以显示您从任何角度都看不到的问题。

成功：快板PCB设计真正的DFM技术

制造是设计过程的最后一步。但设计中的可制造性问题只能通过回去重新设计来解决。将可制造性检查留到最后，当您发现问题时，您必须从头开始设计。

Allegro PCB DesignTrue DFM Technology在开始设计之前应用您的制造、制造、测试和组装规则，以便根据您独特的规则验证每条路线和每个组件的位置。

视觉错误标记标记铜和非铜功能相关制造、组装和测试问题，以便设计师可以实时纠正它们，而不会对以后的设计产生级联后果。
