Visualization of code execution through 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 visualizing and configuring controller function sequences, the operations comprising:

• analyzing at least one code segment associated with a controller associated with a system to determine at least one function and at least one functional relationship associated with the at least one code segment;
• analyzing hardware change impacts based on at least one functional line-of-code behavior and relation model by:
• identifying a new hardware component associated with the system;
• accessing a first software functionality line-of-code behavior and relation model representing execution of functions using the new hardware component;
• accessing a second software functionality line-of-code behavior and relation model representing execution of functions on a previous hardware component of the system, wherein:
• at least one of the first or second software functionality line-of-code behavior and relation models describes a plurality of symbols and symbol relationships between at least some of the symbols, at least one of the symbol relationships corresponding to the at least one functional relationship;
• and
• one of the symbols represents at least one of:
• a variable, a buffer, a function, a call, an object, a segment of code, the controller, or another controller distinct from the controller;
• performing a functional differential comparison of the first line-of-code behavior and relation model to the second line-of-code behavior and relation model;
• and
• determining, based on the functional differential comparison, a status of functional equivalence between the new hardware component and the previous hardware component;
• generating a report identifying the status of functional equivalence;
• performing a signature operation on at least one of the first and second software functionality line-of-code behavior and relation models to produce a unique signature value;
• linking the unique signature value to at least one of the first and second software functionality line-of-code behavior and relation models;
• displaying at least one of the first or second software functionality line-of-code behavior and relation models at a user interface;
• receiving an input at the user interface;
• and
• in response to the received input, animating the at least one displayed software functionality line-of-code behavior and relation model to visually depict execution of the at least one code segment on the controller, wherein visually depicting execution of the at least one code segment on the controller comprises visually depicting a change in the controller's operation over time.
