    • Some embodiments of the invention provide configurable integrated circuits (“IC's”) with configurable node arrays. In some embodiments, the configurable node array includes numerous (e.g., 50, 100, etc.) configurable nodes arranged in several rows and columns. This array also includes several direct offset connections, where each particular direct offset connection connects two nodes that are neither in the same column nor in the same row in the array. In some embodiments, at least some direct offset connections connect pairs of nodes that are separated in the array by more than one row and at least one column, or by more than one column and at least one row. Some embodiments establish a direct connection by (1) a set of wire segments that traverse through a set of the IC's wiring layers, and (2) a set of vias when two or more wiring layers are involved. In some embodiments, some of the direct connections have intervening circuits (e.g., buffer circuits), while other direct connections do not have any intervening circuits. Also, in some embodiments, the nodes in the configurable array are all similar (e.g., have the same set of circuit elements and same internal wiring between the circuit elements).
    • 本发明的一些实施例提供具有可配置节点阵列的可配置集成电路(“IC”)。 在一些实施例中,可配置节点阵列包括以多行和列排列的许多(例如,50,100等)可配置节点。 该阵列还包括几个直接偏移连接,其中每个特定的直接偏移连接都连接两个不同于列的节点,也不在阵列中的同一行中。 在一些实施例中,至少一些直接偏移连接将在阵列中分离的多对节点连接多于一行和至少一列,或多于一列和至少一行。 一些实施例通过(1)一组穿过一组IC布线层的线段建立直接连接,以及(2)当涉及两个或多个布线层时的一组通孔。 在一些实施例中,一些直接连接具有中间电路(例如,缓冲电路),而其它直接连接不具有任何中间电路。 此外,在一些实施例中,可配置阵列中的节点都是相似的(例如,具有相同的电路元件组和电路元件之间的相同的内部布线)。
