Patent AT-E400853-T1: [Translated] METHOD AND APPARATUS FOR FORMAL CIRCUIT VERIFICATION

Published by National Center for Biotechnology Information (NCBI) | U.S. Department of Health & Human Services | Metadata Last Checked: September 07, 2025 | Last Modified: 2025-09-06
A method and apparatus for determining the time behavior of a digital circuit based on a starting assumption is disclosed. Generally, in a formal verification of a digital circuit, the time behavior of a digital circuit is monitored to verify or refute whether formulated properties, which comprise an assumption and an assertion, result as a consequence of a presence of an assumption in the digital circuit. In order to determine the behavior of the digital circuit, the time behavior of the digital circuit is examined from a starting initial state of the digital circuit. A relevant auxiliary property is activated and the assertion of the auxiliary property is added to the digital circuit. The digital circuit is then monitored over a period of time.
