    • An integrated circuit (IC) is provided. The IC includes a first region having an array of programmable logic cells. The IC also includes a second region incorporated into the IC and in communication with the first region. The second region includes standard logic cells and base cells. In one embodiment, the standard logic cells are assembled or interconnected to accommodate known protocols. The base cells include configurable logic to adapt to modifications to emerging communication protocols, which are supported by the base cells. The second region can be embedded in the first region in one embodiment. In another embodiment, the second region is defined around a perimeter of the first region. The configurable logic may be composed of hybrid logic elements that have metal mask programmable interconnections so that as emerging communication protocols evolve and are modified, the IC can be modified to accommodate to the changes in the protocol. In another embodiment, a generic device can be customized by replacing the original function with a completely new function targeting a specific application space, e.g., replacing the original function such as a PCI Express, used for computing based applications, with 4OG /10OG Ethernet and Interlaken, used in wireline applications. A method of designing an integrated circuit is also provided.
    • 提供集成电路(IC)。 IC包括具有可编程逻辑单元阵列的第一区域。 IC还包括结合到IC中并与第一区域通信的第二区域。 第二区包括标准逻辑单元和基本单元。 在一个实施例中,标准逻辑单元被组合或互连以适应已知协议。 基本单元包括可配置逻辑以适应由基本单元支持的新兴通信协议的修改。 在一个实施例中,第二区域可以嵌入第一区域。 在另一个实施例中,第二区域围绕第一区域的周边限定。 可配置逻辑可以由具有金属掩模可编程互连的混合逻辑元件组成,使得随着新兴通信协议的发展和修改,可以修改IC以适应协议的改变。 在另一个实施例中,可以通过用针对特定应用空间的全新功能替换原始功能来定制通用设备,例如用4OG / 10OG以太网替换用于基于计算的应用的诸如PCI Express的原始功能,例如PCI Express, 因特拉肯,用于有线应用。 还提供了一种设计集成电路的方法。
