This technical report is first in a series aimed at establishing a common methodology for FC system signal modeling. Using this methodology, FC systems may be modeled and simulated accurately and consistently. These methodologies may also apply to other transports that use high speed serial communication schemes. This technical report establishes the framework for the exchange of signal performance information between component suppliers, system integrators, and those carrying-out simulations. This report defines the acceptable methods for extracting the electrical and signal performance attributes of the constituent parts of a FC transmitter - receiver connection within a link. It shall be used in conjunction with the requirements within the following documents: FC Physical Interface (FC-PI), FC Physical Interface-2 (FC-PI-2), and FC 10 Gigabit (10GFC).
