A Coverage Analysis for Safety Property Lists
Paper i proceeding, 2007

We present a coverage analysis that can be used in property-based verification. The analysis helps identifying ”forgotten cases”; scenarios where the property list under analysis does not constrain a certain output at a certain point in time. These scenarios can then be manually investigated, possibly leading to new, previously forgotten properties being added. As there often exist cases in which outputs are not supposed to be specified, we also provide means for the specificier to annotate properties in order to control what cases are supposed to be underconstrained. Two main differences with earlier proposed similar analyses exist: The presented analysis is design-independent, and it makes an explicit distinction between intentionally and unintentionally underspecified behavior.
