Task Management & Jira Integration
Yes. Context-aware tasks link comments and to-dos directly to design objects, and bi-directional Jira integration keeps engineering and project-management tools in sync.
No. There is no native task-management layer tied to design objects and no first-party Jira synchronization. Task tracking happens in external tools without design-data context.
Secure Team Scaling (SSO, SCIM & Event Logs)
Yes. Allows SSO and SCIM integration with existing identity systems, user grouping, granular access permissions, and exportable event logs for audit readiness.
Partial. OnCloud offers MFA, regional data hosting, and cloud workspace access management. SSO/SCIM enterprise identity integration and exportable per-user event logs are not documented at parity.

Cloud PLM Synchronization (Duro & Arena)
Yes. Comes with the PLM Module with turnkey connectors for Duro and Arena, keeping engineering data in sync with cloud PLM in one click.
No. Does not include any native Duro integration. Cloud PLM connectivity goes through third-party gateway products targeting Teamcenter, SAP PLM, and similar systems.

Unified Component Management in a Shared Library
Yes. Comes with cloud libraries with a unified component model (symbol, footprint, 3D, SPICE, supplier links), where-used tracking, managed lifecycle states, and extensible component templates.
Partial. Capture, footprint, and padstack libraries remain separate. Unified, parameter-rich component management with where-used reports requires OrCAD CIS plus the optional CIP add-on.
Reusable, Certified Circuit Design Blocks
Yes. Managed schematics and reuse blocks are linked to their source, plus formal certified-circuit reuse so teams share validated IP safely across projects.
No. Paste Special allows manual copy across projects, but there is no managed reuse library for validated circuit blocks or templates.
云服务
Engineering Management
Engineering Visibility & Managed Design Reviews
Yes. Managers get browser viewing, live sharing, commenting, and tasks plus the structured Managed Design Review workflow. Managers can see real-time project status without chasing updates across multiple tools.
Partial. Presto Canvas markup and OnCloud web viewers enable browser review, but there is no checklist-driven, audit-ready managed-review workflow.
Configurable Workflows & Process Control
Yes. Diagram-based workflows automate approvals, ECOs, and lifecycle handoffs, with prebuilt templates that standardize processes and sync with PLM and Jira.
No. There is no native configurable workflow engine for design or release approvals. Equivalent process control requires an external PLM.
Multidisciplinary Engineering Collaboration
Yes. The shared workspace invites unlimited collaborators and external guests. The control layer manages reviews, approval flows, workflows, and ECOs. Collaboration puts ECAD, MCAD, supply chain, and manufacturing on one platform.
Partial. Symphony allows two concurrent PCB designers and OnCloud supports co-design and sharing. However, cross-discipline collaboration is spread across separate apps rather than one governed platform.
Requirements Traceability & Audit-Ready Documentation
Yes. The Requirements Portal, Configurable Lifecycle Management, and audit export combine for end-to-end requirements-to-design traceability with automated documentation.
No. Offers no native requirements-to-design traceability or automated compliance documentation.
Manufacturing Handoff
Version-Controlled Release Packages in Browser
Yes. Release packages (Gerber, ODB++, IPC-2581, BOM, drawings) are stored with version control; manufacturers view and comment via a browser link. Structured release flows tie feedback to the project.
Partial. LiveDoc produces manufacturing packages and OnCloud versions those releases. Does not include a similar structured one-click release-package flow with feedback tied back to the design.
Web-Based Assembly Interface
Yes. The Assembly Assistant provides a paperless, sequential, web-based assembly interface for prototype and short-run production.
No. Offers no equivalent paperless assembly assistant or web-based assembly instruction tool.
Manufacturing Services from Trusted Partners
Yes. Altimade (in Beta) provides in-platform quoting, manufacturability checks, and direct ordering through Altium's vetted CM network.
No. Offers no equivalent in-platform contract-manufacturer marketplace. CM engagement is handled outside OrCAD X.

关于 Altium
自1985年以来，我们持续致力于开发、创建和销售屡获殊荣的电子设计工具（软件和硬件），帮助电子设计人员利用前沿设备和技术，在各类设计“生态系统”中管理项目，并创建互联智能设计。
探索最佳选择：Altium Designer 还是 PADS ？
对于 Altium Designer 用户来说，最大的优势在于其强大的电子开发功能，以及能够在单一程序中访问所有关键的 PCB 设计功能。相比之下，PADS 用户需要花高价购买多个程序的许可证，才能获得相同的功能。Altium Designer 的直观界面和全套设计工具能够为大型团队和资深专业人士提供可靠的项目保障：
- 全面的多通道、层次式原理图输入
- Altium Designer 的集成模拟混合信号仿真引擎包括 SPICE 功能和 IBIS 模型支持
- 原理图输入工具使您能够访问本地或云端托管综合元件库
- 多项功能使项目、文件和设计复用变得快速而简单
- Altium Designer 的层堆栈计算器包含一个用于精确阻抗计算的内置场求解器
- Altium Designer 的 PCB 布线工具相较于 PADS 更易于使用，并能保持您的工作效率
- 通过 Altium Designer 内的 PCB 库数据访问汇总的实时采购数据
- 通过 Altium 365™平台与您的团队协作并共享设计数据
您的 PCB 设计软件应该帮助您保持竞争力和生产力，因此，您需要一款能够一站式满足您从设计到制造的所有需求的程序。PADS 仍在使用过时的应用程序结构，并将重要功能拆分到需要单独购买的不同程序中。与之不同的是，Altium Designer 在单一应用程序中提供与 PADS 相同的高级工具，并提供了专业界面和简化的学习路径。与其在 PADS 上为少数工具花更多的钱，不如开始使用行业领导者和专业 PCB 设计师都在用的软件吧。
从 PADS 切换到 Altium Designer ？
如果您是现有的 PADS 用户，您可以轻松切换到 Altium Designer 并立即着手设计。Altium Designer 提供了转换工具，让您能够轻松地将旧库和项目导入到 Altium 的文件格式中。所有 Altium Designer 用户都可以访问免费的在线资源，以了解更多有关 Altium 前沿设计工具、基本原理、先进技术、创新功能等方面的信息。Altium 是唯一一款为 PCB 设计师打造的专属解决方案。
