Formal languages are increasingly used to describe the functional requirements of circuits. Although formal requirements can be hard to understand and subtle, they are seldom the object of verification. In this paper we present our requirement analysis tool,
RAT
. Our tool supports quality assurance of formal specifications. A designer can interactively explore the requirements’ semantics and automatically check the specification against
assertions
(which must be satisfied) and
possibilities
(which describe allowed corner-case behavior). Using
RAT
, a designer can also investigate the realizability of a specification.
RAT
was successfully examined in several industrial projects.
