    • Various techniques are described to identify composite wires from segmented wires of a programmable logic device (PLD). In one example, a method includes identifying a plurality of interface templates corresponding to tiles of the PLD. The PLD comprises a plurality of segmented wires arranged in a plurality of tiles. Each interface template corresponds to at least two adjacent tiles of the PLD and identifies connections between segmented wires of the corresponding adjacent tiles. The method also includes associating the segmented wires of the PLD with a plurality of wire index values based on the connections identified by the interface templates. The method further includes identifying a plurality of composite wires according to the wire index values. Each composite wire comprises a set of the segmented wires associated with a corresponding one of the wire index values. The composite wires are adapted to interconnect programmable logic blocks of the PLD.
    • 描述了各种技术来识别来自可编程逻辑器件(PLD)的分段导线的复合线。 在一个示例中,一种方法包括识别与PLD的瓦片相对应的多个界面模板。 PLD包括布置在多个瓦片中的多个分段导线。 每个接口模板对应于PLD的至少两个相邻的瓦片,并且识别相应相邻瓦片的分段导线之间的连接。 该方法还包括基于由接口模板识别的连接,将PLD的分段线与多个线索引值相关联。 该方法还包括根据导线索引值识别多个复合导线。 每个复合线包括一组与线索引值相对应的分段线。 复合线适于互连PLD的可编程逻辑块。
