An animated graphical simulator for the IEEE 1596 scalable coherent interface, with real-time extensions

As part of the Very High Speed Optical Networks (VHSON) Demonstration Program, a simulator has been developed. The Scalable Coherent Interface Network Interface Functional Simulator (SCINIFS) addresses the Institute of Electrical and Electronic Engineers (IEEE) standard 1596-1992 for the Scalable Coherent Interface (SCI). In addition, SCINIFS addresses the evolving work of IEEE project P1596.6, entitled SCI Real-Time (SCI/RT). The SCI/RT project addresses extensions to IEEE Standard 1596 that seek to enhance SCI´s utility for real-time fault-tolerant computing applications. SCINIFS addresses the functional behavior and performance of SCI/RT nodes when connected in a ring. The development of the simulator, early results and future work to model SCI switches are described
