Latest Patents
One of Wilcox's latest patents is focused on software verification by fault insertion. This invention involves an integrated circuit that incorporates boundary-scan facilities in accordance with IEEE Standard 1149.1. The boundary scan chain is configured to allow fault insertion testing of diagnostic and maintenance software. Each scan cell includes storage devices for a pair of bits of a binary vector, where one bit comprises faulty data and the other bit controls the application of that faulty data. This system includes a controller that manages the IEEE test interface to shift the binary vector into the boundary scan chain, along with software for diagnosing faults in the integrated circuits.
Another significant patent by Wilcox is an integrated circuit testing method and apparatus. This invention addresses the challenges associated with the storage and handling of vast amounts of data from increasingly complex devices. It proposes testing a pair of identical integrated circuits simultaneously, using the binary vector generated by scanning one as a reference against the other. This method allows for a more efficient comparison of integrated circuits, potentially connected in series or a ring configuration.
