Direct mapping from Petri nets (PN) and Signal Transition Graphs (STG) avoids algorithmic complexity inherent in logic synthesis methods based on optimal state encoding. However, it may lead to inefficient implementation, both in size and performance, due to excessive use of state-holding elements.This paper presents a set of tools that optimise logic produced by the direct mapping technique by means of: exposure of outputs, detection and elimination of redundant places. Output exposure is an approach to exp…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
