System and method for analyzing lengths of branches of signal paths

A system for analyzing lengths of branches of signal paths, the system comprising:

• a signal path naming module programmed for naming all signal paths of a printed circuit board (PCB), and storing the naming information into a database;
• a signal path group selecting module programmed for selecting a group of signal paths to be analyzed from the database according to the naming information;
• a signal path selecting module programmed for selecting signal paths to be analyzed from the group of signal paths;
• a branch searching module programmed for analyzing the selected signal paths, to search passive circuit components and external circuits connected to the selected signal paths for corresponding branches of the selected signal paths;
• a branch length calculating module programmed for calculating a length of each branch;
• and
• a branch length comparing module programmed for comparing each calculated branch length with a corresponding predefined maximal branch length that is stored in the database, and determining whether the calculated branch length is more than the predefined maximal branch length.
