Abstract
An analysis tool that generates properties for a circuit design. The debugging tool receives a circuit design encoded in a hardware description language. The tool identifies portions of the circuit design that correspond to features of interest (e.g., counters, finite state machines, one hot vectors, etc) in the circuit design. Each portion of the circuit design has a cone of influence, and the tool identifies control signals from within the cones of influence. By identifying control signals in this manner, the tool can then generate the properties based on values for the control signals and the identified portions of the circuit design that are obtained from data describing the operation of the circuit design over a number of clock cycles (e.g., simulation data). The result is one or more properties that are likely to represent a relevant behavior of the circuit design.
