Abstract:An integral part of the IBM eServer z990 I/O subsystem is the self-timed interface (STI) switch chip. The STI switch is an application-specific integrated circuit (ASIC) designed to provide high I/O connectivity and high bandwidth within the system. The complexity of the functional verification of the STI switch chip is inherent in the implementation of seventeen logical clock domains and the support of six different STI interfaces with programmable frequencies. The logic within these clock domains is connecte… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
