Model comparison device and model comparison tool

摘要

PROBLEM TO BE SOLVED: To provide a device for presenting substantial difference in two models.SOLUTION: A development support device compares an original model with an alteration model obtained by altering the original model. Unique identifiers are set in respective components (blocks, connection) of the models, and the development support device detects components deleted from the original model and newly added components on the basis of the identifiers (S325, S335, S345). In addition, parameters of the components in which the same identifier is set with one another (S365), and when the components are connection, substantial connection destinations of the connection are compared with one another by referring to a block to be indirectly connected via an import block or an export block in a subsystem in consideration of the case when the connection is made into a subsystem or the subsystem is dissolved.
