Phạm vi áp dụng / Scope of standard

This Standard establishes a common methodology for SCSI system signal modeling. Using this methodology, SCSI systems may be modeled accurately and consistently. This Standard establishes the requirements for the exchange of signal performance information between component suppliers, system integrators, and those carrying-out simulations. This Standard defines the acceptable methods for extracting the electrical and signal performance attributes of the constituent parts of a SCSI bus segment. This Standard establishes the acceptable methods for modeling these parts. It shall be used in conjunction with the requirements within the SCSI Parallel Interface (SPI-x) family of standards.

The objectives of the SCSI Signal Modeling (SSM-2) Standard are to:

a) create a framework that shows how SCSI signal modeling fits within the context of a SCSI bus segment,

b) define the modeling parameters of the component sets,

c) define a set of elemental components of the SCSI parallel interface,

d) define a set of composite components of the SCSI parallel interface,

e) define the interface boundaries of the component sets,

f) define the general signal modeling methodologies that apply to the SCSI parallel interface,

g) define the only acceptable model types and formats for the exchange of performance information and model structure for each component,

h) define the methodology for translating between physical measurements and necessary modeling parameters, and

i) define a method for the exchange of information between component suppliers and system integrators.
