Abstract
Apparatus for presentation of functional coverage, including one or more processors and a memory, wherein the memory stores software instructions including instructions for representing a set of attributes of a design under test as a multi-dimensional cross-product space, comprising events corresponding to combinations of values of the attributes to be tested, the events comprising legal and illegal events, instructions for running at least one test on the design, instructions for identifying, responsively to the at least one test, a first group of the legal events that were covered by the at least one test and a second group of the legal events that remain non-covered after the at least one test, instructions for grouping one or more of the illegal events with at least one of the first and second groups so as to generate a simplified model of the functional coverage of the events in the cross-product space and instructions for presenting the simplified model of the functional coverage on an output device. The apparatus further includes an output device coupled to the coverage processor to present the simplified model of the functional coverage to a user.
