您几周或几个月前开发的电路以稍微修改或增强的形式可疑地出现在另一家公司的设备或系统中。或者，您是一家IP提供商，您已经通过葡萄藤听说您的客户正在构建更多的芯片或盒子，而不是他们与您签署的许可协议赋予他们的权利。所有这些情况，以及其他几分钟的“假设”思维将揭示的有害场景，不幸的是，您是设计盗窃的受害者。在一般概念的一种表现形式中，有人可能会对您的整个设计进行精确的复制，本文将这种技术称为“克隆”。另一种更难但可能更具破坏性的盗窃形式是“逆向工程”。在这种情况下，有人使用存储在可编程逻辑器件中的信息来重建原始电路的细节，然后修改这些细节，并将其部分或全部纳入其他设计中。设计盗窃历来是军事项目最受关注的问题。但是，随着可编程逻辑的集成能力和性能的提高，以及每门成本的下降，克隆和逆向工程的潜力成为越来越多和各种各样的更广泛的应用程序的关注。AS可编程逻辑在大容量领域的不断入侵仍然存在根本限制
circuit you developed just weeks or months ago has suspiciously appeared in another company’s device or system in a slightly modified or enhanced form. Or maybe you’re an IP provider, and you’ve heard through the grapevine that your customer is building more chips or boxes than the license agreement they signed with you gives them the right to do. All of these situations, as well as other detrimental scenarios that a few minutes of “what-if ” thinking will uncover, unfortunately suggest that you’re the victim of design theft. In one manifestation of the general concept, someone might make an exact duplicate of your entire design, a technique that this article refers to as “cloning.”The other harder but possibly even more damaging form of theft is “reverse-engineering.” In that scenario, someone uses the information stored in the programmable-logic device to reconstruct the original circuit details and then alters and incorporates those details in part or whole into other designs. Design theft has historically been of greatest concern with military projects. But, as programmable logic’s integration capability and performance rise and as cost per gate plummets, the potential for cloning and reverse-engineering becomes a concern for an increasing number and variety of broader-based applications. Fundamental limits still exist as to the AS PROGRAMMABLE LOGIC INCREASINGLY ENCROACHES ON HIGH-VOLUME TERRITORY
