Platform and method for automatically generating design schematic diagram of automatic test system

The invention discloses a platform and method for automatically generating a design schematic diagram of an automatic test system, wherein the platform comprises an input module for instrument device resource and connection constraint relationship, a database module, a database management module, a parameter selection and pre-processing module, an automatic layout module, an automatic routing module, as well as a drawing result display and storage module. A user inputs data via the input module for instrument device resource and connection constraint relationship; the parameter selection and pre-processing module is used for grouping and grading instruments according to the parameters selected by the user; the automatic layout module is used for performing an automatic layout operation; and the automatic routing module is used for finishing a routing operation. The method disclosed by the invention is mainly provided for finishing an automatic layout based on a method of intersecting the fewest lines, and fin
