SCRAMBLE COMPILER AND DETECTING METHOD FOR ERRONEOUS DESCRIPTION

PROBLEM TO BE SOLVED: To detect its erroneous description even when an erroneous description other than a language description level exists in a scramble logic equation. SOLUTION: A file selecting section 102 selects a desired source file from a source file storage device 20. A language analyzing section 104 analyzes whether an erroneous description of a language description level exists in the contents of the source file, or not. An operation processing part 106 operates conversion data of the source file having no error of a language description level based on its scramble logic expression. An operation check section 110 checks whether the same value is included in the conversion data from the operation processing section 106 or not, when conversion data including the same value is detected, the result is displayed on a display device. In consequence of operation check, when no error is detected, an object file indicated by conversion data through a file output section 108 is outputted.
