Patent ID: 7099812

Claim:
A grid that monitors a design simulation to support design verification coverage analysis, comprising: a monitor declaration that provides a unique name for the grid; n ordered axis declarations wherein n is at least 1, each said axis declaration names an axis comprising a first axis through a nth axis, wherein each said axis corresponds to a functional attribute of the design and has an axis size that comprises two or more functional states of said functional attribute and has a corresponding axis variable; one or more logic expressions that evaluate whether the design has achieved one or more of said functional states, said logic expressions set each one of said n axis variables to an integer value corresponding to said functional state when said logic expressions evaluate true; and a grid declaration that converts said n axis variables to an integer that is a unique linear index value that corresponds to the cross-product of said functional states achieved by the design, said grid declaration also records a hit at said unique linear index value.
