Described are reverse engineering data analysis systems, and integrated circuit component data processing tools and methods thereof. A system can comprise: a data storage device operable to store a data structure comprising extracted IC component data nodes representative of corresponding IC components of target IC and a connectivity therebetween; a graphical user interface (GUI); and a digital data processor operable on said data structure to: render, via said GUI, a dynamic graph of said data nodes; graphically migrate at least some of said data nodes on said dynamic graph as a function of a connectivity thereof with other nodes, wherein connected nodes are attractively displaced relative to one another such that said migrating nodes progressively cluster with related nodes to define distinct IC component clusters representative of distinct groups of related IC components of the target IC, whereas unconnected notes are repulsively displaced so to progressively distance said unconnected nodes.

Reverse engineering data analysis system, and integrated circuit component data processing tool and method thereof

A system is disclosed for displaying circuitry interconnections as flightlines between a component specified as the local component and the foreign components connecting to the local component. Upon obtaining data of the circuit components and interconnections, a user can designate the local component from among all of the circuit components. The system determines the foreign components connected to that local component, retrieves the flightline appearance display settings for the computer display, and renders a view of the specified local component and its foreign components with flightlines representing each interconnection connection. The flightlines can be color coded to indicate inputs, outputs or other characteristics of interest to the user.

Circuit visualization using flightlines

Methods and systems are provided to reduce the complexity of sequential digital circuitry including cells of unknown function by grouping and defining like instance of combinational circuitry cells. The system groups together cells that feed into the same combination of one or more state cells. The groups of cells are then replaced by clouds which are defined in the netlist for the sequential digital circuitry to produce a simpler representation of the circuitry for analysis purposes and to aid in determining the function of those cells for which the function is unknown.
