This technical report is intended to establish a common methodology so that signals in FC systems may be modeled and simulated accurately and consistently. It establishes the requirements for the exchange of performance information between components suppliers and system simulators. It defines the acceptable methods for extracting the electrical and performance attributes of the constituent parts of the FC copper and optical interface. It establishes a common methodology for simulating the FC physical environment. It shall be used in conjunction with the requirements within the following documents: FC Physical Interface (FC-PI; ANSI INCITS 352-2002), FC Physical Interface-2 (FC-PI-2; ANSI INCITS 404:2006), FC 10 Gigabit (10GFC;ANSI INCITS 311:2003), FC Physical Interface-3 (FC-PI-3, T11/1625- D), and FC Physical Interface-4 (FC-PI-4, T11/1647-D).
