Method for generating test files from scanned test vector pattern drawings

摘要

A graphical bitmap image of a scanned test pattern drawing is transformed into a test file in a file format that is readily usable to provide stimuli for computer-aided design (CAD) tools or integrated circuit (IC) testing equipment. A bitmap image of each page of the test pattern drawing is produced as a graphical image of the rows and columns of test pattern data. Non-essential drawing symbols are then removed from the bitmap image, such as the lines used to draw the table. Essential test pattern information is recognized and is converted into a machine readable format by first storing the data in a tabular format having rows and columns which correspond to the rows and columns of the test pattern drawing. The stored test pattern data is then integrated with a machine readable file format which is adaptable to the CAD and IC tool in order to produce the machine readable test file.
