Abstract

PURPOSE:To recognize a plurality of active elements based on one cell of the active elements of the artwork data of ICs and LSIs for bipolar operations, by combining the names of the cells and the names of texts at lower levels in a hierarchy, which are included in a common region in alignment with the diffused patterns of the artwork data, and expressing the texts. CONSTITUTION:As the artwork data of an integrated circuit, the name of the kind of each terminal and the names of the cells, which are the rectangular data of the artwork data, are referred, and the circuit is recovered. In this element recognition system, the names of the cells in the lower levels in a hierarchy, which are included in a common region, and the names of texts are combined in alignment with the diffused patterns of the artwork data, and the texts are expressed. A plurality of elements, which are included in one cell, can be recognized. For example, lower hierarchical level cells 7 are nested beneath upper hierarchical level cells 6. When the common region of transistors, which are formed at the hierarchical levels is a collector terminal having a text 8 of a collector 'C', the text is expressed as shown in the Figure.

Among the element recognition methods described above, when recognizing from text expression, all active elements in the artwork data are converted into cells, and cells dedicated to terminal text are further nested (hierarchical structure) in the cells. Text is provided for each terminal. However, when multiple active elements having a common area are configured with the same cell, the cell hierarchy is deepened by one layer, and the structure is such that a cell is provided and further text is provided. However, due to the difference in the hierarchy between the terminal text included in the common area and the other terminal texts, there is a drawback that all but one of the multiple elements are recognized as missing terminals.

To compensate for this drawback, as shown in Figure 5, it is necessary to add only texts 8 and 8' for the number of elements belonging to the common area of text C representing the collector terminal. However, it also had the disadvantage of requiring a large amount of man-hours to create the data.
