Abstract
The disclosed invention is a grid that monitors a design simulation to support design verification coverage analysis. The disclosed invention includes n ordered axis declarationsthat each correspond to a functional attribute and list at least two valid functional states, logic expressionsthat test for the functional states and set axis variables, and a grid declarationthat converts the axis variables to a unique linear index value corresponding to the cross-product of the achieved functional states and records hits. The linear index is calculated by multiplying the integer value of each axis variable (except the nth axis variable) by the product of the sizes of each higher-order axis than the axis to which said axis variable corresponds, summing the results, and adding the integer value of the nth said axis variable.
