JPS57153444A - Determining processing system for route - Google Patents

Abstract

PURPOSE:To accelerate processing by previously removing the route, which need not be check-processed, on the basis of the coordinates of the starting point and end point of the route and the mode of the existence of an obstacle pattern when the route is determined in order to automatically prepare a mask figure, a printed board pattern figure, etc. by an LSI. CONSTITUTION:The route determining processing system is formed by a starting point.end point coordinate input section 7, an obstacle pattern-memory 8 and a route determining arithmetical section 9. In such constitution, a processing mode selective processing section 10, a processing mode memory 11, a reading register 12, a direction lengthening-route determining processing section 13 and a display processing section 14 are mounted into the arithmetical section 9. When the starting point and the end point are given from the input section 7, the pattern is read by means of the memory 8 in response to the points, and a positional relationship with the obstacle pattern is inspected at first. A processing mode is selected by means of the processing section 10 on the basis of the information, the memory 11 is accessed, the information is read by means of the register 12, and forwarded to the processing section 13, and the processing mode is displayed to the processing section 14.
