    • A method for identifying an area of a chip to be probed proceeds as follows. A callout list of failures is obtained from a tester, the list including cell name and pin for each failure. A Def file is interrogated to locate a Def entry matching the cell name, and a cell type, cell location, and cell orientation data is obtained for the cell from the Def file. A Lef file is then interrogated to locate a Lef entry matching the cell type, and the coordinates of the pin are obtaining from the Lef file. A GDS file is interrogated to locate a GDS entry matching the cell type, and the coordinates of polygons listed in the GDS entry are obtained. The coordinates of the pin are then crossed with the coordinates of the polygons to identify overlapping area. The overlapping area is defined as the location to be probed. A driving signal is applied to a stage to align a prober with the location to be rprobed.
    • 用于识别要探测的芯片的区域的方法如下进行。 从测试人员获得故障排除列表,该列表包括每个故障的单元名称和引脚。 询问Def文件以查找与单元名称匹配的Def条目,并从Def文件获取单元格的单元格类型,单元格位置和单元格方向数据。 然后询问Lef文件以找到与单元格类型匹配的Lef条目,并且从Lef文件获取引脚的坐标。 询问GDS文件以定位与单元格类型匹配的GDS条目,并获取GDS条目中列出的多边形的坐标。 然后将引脚的坐标与多边形的坐标交叉以识别重叠区域。 重叠区域被定义为要探测的位置。 驾驶信号被施加到舞台,以将探测器与要被翻转的位置对准。
