Abstract

In automatically generating a source code from a block diagram, it is essential to efficiently confirm the validity of the source code that is converted from the block diagram, and also in cases of starting usage of a new code generating tool, it is important to efficiently confirm the validity of that code generating tool. In order to perform this task, the design assistance device for software of the present invention automatically generates source code based on a block diagram describing the processing procedure for controlling a device for control by utilizing plural block elements and the connective relation between those plural block elements. The design assistance device for software generates a first data flow expressing the block diagrams and their connective relation by using nodes and links; generates a second data flow expressing the dependent relation among functions or variables in the source code by utilizing nodes and links; and finds and outputs the coincidence between the first data flow and second data flow.
