Abstract

Symbolic model checking is a successful technique for checking properties of large finite-state systems. This method has been used to verify a number of real-world hardware designs; however it is not able to determine timing or performance properties directly. Since these properties are extremely important in the design of high-performance systems and in time-critical applications, we have extended model checking techniques to produce timing information. Our results allow a more detailed analysis of a model than is possible with tools that simply determine whether a property is satisfied or not. We present algorithms that determine the exact bounds on the time interval between two specified events and the number of occurrences of another event in such an interval. To demonstrate how our method works, we have modelled the PCI local bus and analyzed its temporal behavior. The results demonstrate the usefulness of our technique in analyzing complex modem designs.
