Identifying software interdependencies using line-of-code behavior and relation models

A non-transitory computer readable medium including instructions that, when executed by at least one processor, cause the at least one processor to perform operations for identifying software interdependencies, comprising:

• generating a functional line-of-code behavior and relation model representing functionality of a first portion of code associated with a first controller and functionality of a second portion of code associated with a second controller by applying static or dynamic analysis to the first and second portions of code, the functional line-of-code behavior and relation model modeling symbols and symbol relationships based on the first and second portions of code;
• determining, based on the functional line-of-code behavior and relation model, an interdependency between the second portion of code and the first portion of code and a strength of the interdependency;
• and
• generating at least one of a report or a visual depiction identifying the interdependency and the strength of the interdependency.
