SUMMARYThis paper presents a cooperative design-view environment for interactive partitioning applications. This environment provides the user with a comprehensive viewing facility that describes the potentially complex relationships between various design objects. Using this environment, the user is able to evaluate and analyse design results visually throughout the entire partitioning process. We have developed a graphical user interface (GUI) environment for the ZnterPur system which supports mixed automatic and manual partitioning for multiple-field programmable gate array (FPGA) designs. The preliminary experiments have shown that the use of ZnterPur may lead to a new direction for the exploration of new partitioning approaches based on the circuit-structure analysis.
In this paper, we present EMPAR, an interactive synthesis environment for hardware emulations. EM-PAR provides an open-ended design environment for the development of hardware emulators, which is capable of supporting: (1) a variety of EM architectures (2) a variety of EM synthesis algorithms, (3) interactive control by the user, and (4) design quality analysis. An X-window based graphical user interface has been developed to support a variety of interactive design tasks. The key features in EMPAR are: (1) it is open-ended so that arbitrary algorithms and tools can be built on top of it and (2) it is fully interactive and leaves the control to the designer. EMPAR can be used as a design epvironment for existing hardware emulators as well as a test bed for the evaluation and development of new hardware-emulator architectures and synthesis algorithms.
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.
