This volume contains the proceedings of the conference on Computer Aided V- i?cation (CAV 2002), held in Copenhagen, Denmark on July 27-31, 2002. CAV 2002 was the 14th in a series of conferences dedicated to the advancement of the theory and practice of computer-assisted formal analysis methods for software and hardware systems. The conference covers the spectrum from theoretical - sults to concrete applications, with an emphasis on practical veri?cation tools, including algorithms and techniques needed for their implementation. The c- ference has traditionally drawn contributions from researchers as well as prac- tioners in both academia and industry. This year we received 94 regular paper submissions out of which 35 were selected. Each submission received an average of 4 referee reviews. In addition, the CAV program contained 11 tool presentations selected from 16 submissions. For each tool presentation, a demo was given at the conference. The large number of tool submissions and presentations testi?es to the liveliness of the ?eld and its applied ?avor.
