Abstract [eng] |
As sizes of circuits are shrinking and the clock speed is increasing, functional delay tests are receiving more attention within each day. Based on circuits “black-box” behavioural description, it is possible to generate a high quality functional delay test at initial circuits design stages, which covers more than 99% of all circuits’ transition faults. To make more reliable and speed up the process of finding a better functional delay test generating method, an experimenting system was developed. One of the system`s main features is its capability of automatically storing data files to their set destination directories, which lowers the risk of human being error-prone. This thesis analyses methods used for creating functional delay tests and suggests four more implementations using activity vectors. By using partly automated experimenting system, all four methods were tested, together with the experimenting system. The results reveal how much the functional delay testing process speed up using automated system compared to launching all the testing tasks personally. As experimenting system automatically creates functional delay test method comparison table, it was possible to easily evaluate the most acceptable method that produces tests with high fault coverage and low test size. |
