With the genomic sequencing of Arabidopsis nearing completion and rice sequencing very much in its infancy, a key question is whether we can exploit the Arabidopsis sequence to identify candidate genes for traits in cereal crops using a map-based approach. This requires the existence of colinearity between the Arabidopsis and cereal genomes, represented by(More)
This paper describes a hierarchical design verification system, consisting of a logic verification subsystem, MIXS (1), a timing verification sybsystem, NELTAS(2), and a hierarchical data base. MIXS is a mixed level simulator, which can handle both functional and chip or gate level models with a unified simulation mechanism based on “node” model(More)
A special purpose hardware machine, which simulates up to one half million gates and 2M byte RAM ICs at a 5 millisecond clock speed, is described. This is accomplished with a <underline>HA</underline>rdware Logic (HAL) simulator. This performance is achieved with 32 distributed special parallel processors, which utilize Block Oriented Simulation Technique.(More)
A mixed level simulator, MIXS, is a logic verification tool which has multiple simulation capabilities. Main MIXS techniques are time wheel and selective trace algorithm for functional level simulation based on 'node' model concept and the linkage function of functional models, described in different detail, with network information. The mixed level(More)
This paper describes a mixed level hardware logic simulation system, called Hardware Logic Simulator II (HAL II). This paper first shows a HAL II simulation method. Then, it overviews HAL II hardware and software system configurations, simulation mechanism and estimates system performance. The HAL II system can handle a maximum of 5.8 million gates and a(More)
Gray leaf spot (GLS), caused by Magnaporthe oryzae (anamorph Pyricularia oryzae), in ryegrasses is a very serious problem. Heavily infected small seedlings die within a matter of days, and stands of the grasses are seriously damaged by the disease. Thus, the development of GLS-resistant cultivars has become a concern in ryegrass breeding. Phenotypic(More)
