    摘要: Systems and methods for modeling test space for verifying system behavior, using one or more auxiliary variables, are provided. The method comprises implementing a functional coverage model including: one or more attributes, wherein respective values for the attributes are assigned according to a test plan, and one or more constraints defining restrictions on value combinations assigned to the attributes, wherein the restrictions are Boolean expressions defining whether said value combinations are valid; determining a set of valid value combinations for the attributes that satisfy the restrictions to define the test space for verifying the system behavior; and determining relevant auxiliary variables and a corresponding function for said auxiliary variables to reduce the complexity associated with modeling the test space.
