    • The exemplary embodiments provide a resilient integrated circuit. An exemplary IC comprises a plurality of composite circuit elements, a state machine element (SME), and a plurality of communication elements. Each composite circuit element comprises an element interface and a selected circuit element which may vary by element type, and which may be configurable. The state machine element assigns various functions based on element type, such as assigning a first configuration to a first element type, assigning a second configuration to a second element type, and providing a first data link for the corresponding assignments. In response to detection of a fault or failure, the state machine element re-assigns the first configuration to another composite circuit element and creates a second data link for performance of the same function. The assignment, routing, fault detection, and re-assignment and data re-routing can occur in real time for a wide variety of programs and algorithms, providing for the IC to continue the same functioning despite defects which may arise during operation.
    • 示例性实施例提供了一种弹性集成电路。 示例性IC包括多个复合电路元件,状态机元件(SME)和多个通信元件。 每个复合电路元件包括可以由元件类型变化的元件接口和所选择的电路元件,并且其可以是可配置的。 状态机元件基于元素类型分配各种功能,例如将第一配置分配给第一元素类型,将第二配置分配给第二元素类型,以及为相应的分配提供第一数据链接。 响应于故障或故障的检测,状态机元件将第一配置重新分配给另一个复合电路元件,并创建用于执行相同功能的第二数据链路。 分配,路由,故障检测和重新分配以及数据重新路由可以实现多种程序和算法的实时性,从而尽可能在运行过程中出现缺陷,使IC能够继续相同的功能。

    • Integrated circuit chip design in which a technology-independent description of an integrated circuit design is obtained. A first component is selected from a pre-defined first library based on the technology-independent description, and an interconnection is specified between the first component and a second component based on the technology-independent description. The first component and the second component are laid out on a surface of the integrated circuit chip so as to obtain an initial layout, and a routing characteristic for the interconnection is estimated based on the initial layout. The first component is then replaced with a new component selected from a pre-defined second library based on the routing characteristic. According to this aspect of the invention, the pre-defined first library is smaller than the pre-defined second library.
    • 集成电路芯片设计,其中获得了与技术无关的集成电路设计描述。 基于与技术无关的描述,从预定义的第一库中选择第一组件,并且基于与技术无关的描述,在第一组件和第二组件之间指定互连。 第一部件和第二部件布置在集成电路芯片的表面上以获得初始布局,并且基于初始布局来估计用于互连的布线特性。 然后,基于路由特性,将第一个组件替换为从预定义的第二个库中选择的新组件。 根据本发明的该方面,预定义的第一库小于预定义的第二库。
