谁会在不幸去世的情况下管理您的遗产？
如果您的办公室和设备被自然灾害摧毁，您的企业会怎么做？
当供应商停止关键组件时，您的企业将如何继续运送产品？
一个好的应急计划可以减轻毁灭性挫折的打击，并帮助组织管理不可预测的事件。
许多电子制造商都需要应急计划。
如果停止使用存储设备，我们会切换到竞争设备。
如果我们的电路板供应商破产，我们在快速拨号上有一个备用供应商。
但是系统的某些部分比其他部分更容易替换。
诸如FPGA和专用集成电路（ASIC）的定制逻辑器件可能特别难以替代。
产品过时或寿命终止（EOL）通知很少在方便的时候出现，并且更换系统设计中的基本元素的成本可能很高。
董事会是否需要重新调整？
您的设备是否有自定义包装？
新芯片是否具有不同的核心电压，焊盘布局和封装尺寸，因此它是否不兼容？
所有这些差异意味着您将不得不重新设计您的电路板以适应您的新设备并考虑路由，电压和时序差异。
根据您的质量程序，这些更改可能需要昂贵的产品重新认证。
至少，系统设计人员需要花费大量时间和精力将替换微芯片集成到系统中，根据旧设计文件重新进行特征描述，并彻底测试修改后的系统以确保生产就绪。
好消息是，在您的系统设计完成之前，您可以开始保护自己免受EOL和其他主要组件中断。
做你的研究
产品EOL通常是纯粹的商业决策。
随着时间的推移，晶圆生产线的使用率最终会下降，而您购买的设备对制造商的利润也会降低。
所有半导体公司都有有限的财务和工程资源;
当他们试图推出新技术或加强主线产品时，支持传统产品变得非常困难。
在某些时候，关闭线路比保持线路运行更具商业意义。
在产品开发之初花点时间了解供应商的长期战略。
询问潜在的定制逻辑供应商他们的商业模式。
向您的行业联系人询问其过程寿命。
搜索每个潜在供应商的EOL通知，并尝试了解其流程生命周期。
在项目开始时进行一些研究可以在产品生命周期中避免重大问题。
避免使用专有IP
FPGA和ASIC供应商有时会提供免费或大幅折扣的知识产权（IP），这在设计过程的早期阶段非常有用。
这有助于您（开发人员）项目的启动成本非常低，这在您审查新产品概念或受限于R＆amp; D资金的情况下非常理想。
但如果IP是专有的，那么您就是在为供应商提供平台。
在创建自定义逻辑器件时，最好选择符合通用规范的行业标准IP。
如果您以后需要更改流程或供应商，此IP基本上是可移植的 - 您通常可以直接从IP提供商处购买许可证，或者至少购买兼容的产品。
保持井井有条
设计文件复杂，庞大，有时在各个贡献者之间分散。
它们通常存储在修订和开发分支的各种状态中。
如果您需要迁移自定义逻辑设备，则需要原始设计数据，并且需要完成。
需要保存RTL或网表，以及时序约束文件，合成脚本，引脚列表，框图，IP信息，存储器配置和时钟结构。
模拟测试台和板级信息还可以帮助您快速准确地将设计转换为另一个半导体工艺。
清楚地标记和存储您的数据的方法将是可访问的，并且可以在未来几年内定位。
检查您的数据存储过程，以考虑将来可能的保留需求。
如果您已收到EOL通知该怎么办
如果您已收到停产通知，请仔细考虑您的选择。
重新评估您的产品预测并确定您的组件差距可能有多大。
尽快与新供应商交谈是个好主意。
替换设备的供应商选择与原始设计一样重要，如果不是更重要的话。
努力了解您的选择并找到符合您的计划和要求的选项。

Who would manage your estate in the event of an untimely death? What would your business do if your office and equipment was destroyed by a natural disaster? How will your business keep shipping products when a supplier discontinues a key component? A good contingency plan can soften the blow of a devastating setback and help an organization manage unpredictable events.
Many electronics manufacturers require contingency plans. If a memory device is discontinued, we switch to a competing device. If our circuit board supplier goes bankrupt, we have an alternate vendor on speed dial. But some portions of a system are more easily replaced than others. Custom logic devices such as FPGAs and application-specific integrated circuits (ASICs) can be particularly difficult to substitute.
Product Obsolescence or End-of-life (EOL) notices rarely come at convenient times and the cost of replacing an essential element in your system design can be high. Will a board re-spin be required? Did your device have custom packaging? Will the new chip have a different core voltage, pad layout and package footprint, and will it therefore not be drop-in compatible? All these differences mean you will have to re-design your board to fit your new device and account for routing, voltage and timing differences.
Depending on your quality procedures, these changes may require a costly product requalification. At the very least, system designers will need to spend significant time and energy integrating the replacement microchip into the system, re-characterizing based on old design files, and testing the modified system thoroughly to ensure it is production-ready.
The good news is that you can begin protecting yourself against EOLs and other major component disruptions long before your system is even designed.
Do your research
Product EOLs are often a pure business decision. Utilization of a fab line eventually drops over time, and the device you’re purchasing becomes less profitable to the manufacturer. All semiconductor companies have finite financial and engineering resources; when they’re trying to launch a new technology or strengthen their mainline offering, it can become very difficult to support legacy products. At some point it just makes more business sense to close down a line than to keep it running.
Take the time to understand your vendor’s long-term strategy at the beginning of product development. Ask potential custom logic suppliers about their business model. Ask your industry contacts about their process longevity. Search for EOL notices from each potential supplier and try to get an understanding of their process lifecycles. A little research at the beginning of a project can save you from major headaches during the product lifecycle.
Avoid proprietary IP
FPGA and ASIC providers sometimes offer free or heavily discounted intellectual property (IP), which can be very helpful in the early stages of the design process. This helps you, the developer, have a very low start up cost for a project, which is ideal when you are vetting a new product concept or strapped with limited R&D funding. But if the IP is proprietary, you are committing yourself to the vendor’s platform.
It’s best to select industry-standard IP, which is built to conform to a universal specification, when creating a custom logic device. Should you later need to change processes or vendors, this IP is largely portable – you can often purchase a license directly from an IP provider, or at the very least buy a compatible offering.
Stay organized
Design files are complex, large, and sometimes scattered between individual contributors. They are often stored in various states of revision and development branches.
If you ever need to migrate a custom logic device, you will need your original design data, and it will need to be complete. RTL or netlists need to be saved, as well as timing constraints files, synthesis scripts, pin lists, block diagrams, IP information, memory configurations, and clocking structure. Simulation test benches and board-level information can also aid in quickly and accurately converting your design to another semiconductor process.
Clearly label and store your data in a method that will be accessible and locatable years down the road. Review your data storage procedures to account for possible retention needs far into the future.
What to do if you’ve already received an EOL notification
If you have already received a discontinuation notice, carefully consider your options. Reevaluate your product forecasts and determine how large your component gap may be. It’s a good idea to talk to new suppliers as soon as possible. Vendor selection for a replacement device will be just as critical as it was for your original design, if not more so. Make an effort to understand your options and find one that aligns with your plans and requirements.
