Nexus message

This documentation page references Altium NEXUS/NEXUS Client (part of the deployed NEXUS solution), which has been discontinued. All your PCB design, data management and collaboration needs can now be delivered by Altium Designer and a connected Altium 365 Workspace. Check out the FAQs page for more information.

Altium NEXUS结合了多项特性和功能，其中包括：

先进的布线技术
支持前沿刚柔结合板设计
强大的数据管理工具
强大的设计复用工具
实时的成本估算和跟踪
动态智能供应链
原生3D可视化和间距检查
灵活的发布管理工具

在统一的设计环境中提供上述所有功能并执行整个设计过程——其设计旨在提供最佳生产率，这在同类产品中尚属首创。

Altium NEXUS的统一性让设计数据可以在不同设计领域之间无缝移动。起初，陡峭的学习曲线似乎阻碍了用户对这个能提高生产率并包含丰富功能的软件的使用。但是，Altium NEXUS特有的核心文档空间提供了快速启动和运行软件的所有信息。从高级概述和分步演练，到通过软件直观界面提供所有具体细节资源，Altium NEXUS文档打造了一棵触手可及的知识树。

Altium NEXUS文档采用版本控制方式。您可以直接通过网页浏览器手动切换至特定版本的文档集，或者在Altium NEXUS中自动访问正确版本。您可以使用内置的F1映射功能和其他文档链接访问您目前正在设计的软件版本所对应的目标文档。

您使用的是不同的设计工具？这不是问题。快速转到可查看其他设计工具界面的文档区域。无论您使用的是PADS®、EAGLE™、Expedition®、xDX Designer®、Allegro®或者其他支持界面，Altium NEXUS均提供导入器和/或导出器，使加入Altium NEXUS成为一种顺畅而安心的体验。

进入PCB设计（以及Altium NEXUS）

您是否是电路板设计和/或Altium NEXUS的新手，不知从何入手？本教程将带您从空白的原理图入手，一直到生成为包含九个元件的简单电路构造裸板所需的文件。

从原理图输入到设计印刷电路板（PCB）的这个设计是一个简单的非稳态多谐振荡器。该电路（左图）使用两个通用的NPN晶体管配置成自运行非稳态多谐振荡器。

本教程涉及您在日常设计工作中会接触到的诸多领域。有哪些更好的方式能够帮助您熟悉并了解这一强大的设计“伙伴”？

Designing with a Connected Workspace

Altium NEXUS includes a Workspace for all your design content which is an integral part of the overall deployed solution. The Workspace works in harmony with your Altium NEXUS design client to provide an elegant answer to the question of handling design data with secured integrity. The Workspace not only provides rock-solid, secure storage of data but also enables re-release of data as distinctly separate revisions – essentially tracking design changes over time, without overwriting any previously released data. It also caters to the lifecycle of the design data, allowing people that need to use the data to see, at-a-glance, what stage the data has reached in its 'life' and therefore what it can be safely used for.

The Workspace is used to manage all design data, including components, domain models, schematic sheets of circuitry, and design templates. Indeed, you can even create and manage your entire design projects directly within the Workspace.

By furnishing a set of reusable design 'building blocks' within the Workspace, you can embark on fresh projects safe in the knowledge that each model, component, and higher-order design element has been ratified and approved for use, with no having to reinvent the wheel as it were. The Workspace becomes both the source and destination of design elements, with each new design utilizing elements released to, and managed through, the Workspace. And by designing only with elements from the Workspace, the integrity of those designs is inherently assured.

The Altium NEXUS design client can connect to the following Workspaces:

Altium 365 NEXUS Workspace – a Workspace hosted on the Altium 365 cloud-based infrastructure platform.
Altium NEXUS Server Workspace – a Workspace provided through the Altium NEXUS Server, a solution installed and managed by your own IT department.

With an Altium 365 NEXUS Workspace, you'll benefit from a richer set of collaborative features, including Global Sharing. And because it is cloud-based, you get the latest version of the Workspace without having to worry about manual upgrades.

Key Benefits of an Altium 365 Workspace

Some of the key benefits that Altium 365 brings to the design table:

Securely share PCB designs with internal and external stakeholders with a web link with which they can view and comment on the design via a web browser on any platform (Mac, Windows, Android, or iOS) and any device (desktop or mobile).
Communicate true design intent early and collaboratively through commenting, co-creation, and visualization of PCB designs. Work from anywhere and connect with anyone with ease. Built-in storage and version control (tightly integrated with the NEXUS design client) ensures that the latest data is available at any time from any device.
Conduct more effective design reviews by allowing users to highlight and mark up a specific component or area on a schematic or layout. Internal/external stakeholders (e.g., managers, other designers, part suppliers, etc.,) can comment and mark up designs simultaneously (much like a collaboration on a Google^® document).
Collaborate with multiple designers. The web browser platform simplifies how designs are visualized and marked up while allowing other designers to connect to the same PCB design with their NEXUS design client to author changes.
Co-design with mechanical designers. Electrical and mechanical engineers can push and pull design data backward and forward in real-time with each being notified when changes have been made by the other. Altium 365 provides native integration between electronic and mechanical domains through a built-in co-designer capability that provides native integration with a variety of MCAD software tools.
Reduce miscommunication and redesign iterations with manufacturing. Compress design cycles with the capability to create formal atomic design releases ensuring a coherent set of manufacturing data. Create a manufacturing package that can be bundled up according to the needs of your specific manufacturing partner.

将设计理念输入原理图

原理图输入是创建电子电路的逻辑表示的过程。当您输入原理图时，以独特的方式将一系列符号（元件）连接在一起，从而创建独一无二的电子产品。当您以电子方式输入原理图时，您不但可以创建高质量的设计印刷图表示，还可以执行相关的设计任务（例如，电路仿真），并可将设计传输至PCB布局工具。

使用电路仿真分析设计

电路仿真允许设计人员在投入制造之前对设计进行验证。可以验证原理，从而快速准确地调整电路。电路仿真也允许设计人员在系统内进行工作台上无法实现的测量。

该仿真器是一个真正的混合信号仿真器，它可以分析包含模拟和数字器件的电路。该仿真器使用事件驱动的XSpice的增强版本。它与SPICE3f5完全兼容，并为一系列PSpice®和LTSpice®器件模型提供支持。

对PCB进行布局

每个电子产品内部均含有印刷电路板（PCB）。如今，电路板上的元件尺寸已经缩小到以毫米为单位而非厘米，线宽也从10密耳间距较宽的线条缩小到紧密排列在一起的2或3密耳的极细线条。不断提高的信号速度也使得PCB互联从利用简单的传输电能的铜导线转变为高速传输线，而这一点需要设计技术来实现。此外，机械方面的要求也变得更加复杂。微型、形状不规则的现代电子产品需要微型、形状不规则的印刷电路板，这就需要刚柔结构的电路板来实现——这种电路板可能有弧形边缘和切口，可以更好的契合元件。

这些挑战可以通过Altium PCB设计技术来解决。
