This technical report is the second in a series aimed at establishing a common methodology for FC system signal modeling. This technical report supersedes FCSM and contains all the information in FCSM deemed desirable to carry forward with appropriate updates. Using the methodology described in this document, signals in 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 among 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 an FC transmitter-receiver connection within a link. It is intended to be used in conjunction with the requirements within the following documents: FC Physical Interface (FC-PI; INCITS 352-2002), FC Physical Interface-2 (FC-PI-2; INCITS 404-2006), FC 10 Gigabit (10GFC; INCITS 311-2003), FC Physical Interface-3 (FC-PI-3), and FC Physical Interface-4 (FC-PI-4).
