    • In an embodiment, a design methodology and tools to implement the methodology are used to perform scan insertion in an integrated circuit design. The physical location of the scan chains within the boundaries of the integrated circuit may be determined, and the methodology may use the physical information to perform the scan insertion. For example, the physical information may include the location of the inputs and outputs of the scan chains, as well as routability data indicating the ability to insert interconnect in the integrated circuit to make the desired scan connections. The location and routability information may be used to group scan chain inputs and outputs for, e.g., compression/decompression logic. Using physical data to insert scan compression/decompression logic may reduce the amount of area occupied by the scan logic and connectivity, in some embodiments.
    • 在一个实施例中,用于实现该方法的设计方法和工具用于在集成电路设计中执行扫描插入。 可以确定扫描链在集成电路的边界内的物理位置,并且该方法可以使用物理信息来执行扫描插入。 例如,物理信息可以包括扫描链的输入和输出的位置,以及指示在集成电路中插入互连以进行期望的扫描连接的能力的可路由数据。 位置和可路由性信息可用于对例如压缩/解压缩逻辑的扫描链输入和输出进行分组。 在一些实施例中,使用物理数据插入扫描压缩/解压缩逻辑可以减少扫描逻辑和连接所占用的面积的量。
