本标准定义了一种通用的方法，用于准确、高效地建模和模拟SCSI系统 始终如一地。它规定了双方性能信息交换的要求 组件供应商和系统模拟器。它定义了提取数据的可接受方法 SCSI并行接口组成部分的电气和性能属性。它建立了一个 模拟SCSI物理环境的常用方法。它旨在用于 与SCSI并行接口（SPI-x）标准系列中的要求相结合。

This standard defines a common methodology for modeling and simulating SCSI systems accurately and consistantly. It establishes the requirements for the exchange of perfomance information between components suppliers and system simulators. It defines the acceptable methods for extracting the electrical and perfomance attributes of the constituent parts of the SCSI parallel interface. It establishes a common methodolgy for simulating the SCSI physical environment. It is intended to be used in conjunction with the requirements within the SCSI Parallel Interface (SPI-x) family of standards.
