This coefficient defines how power is dissipated from the Xilinx® device to the environment (device junction to ambient air). Typically this option is calculated by XPE, taking into account, among other things, the different environment parameters in the Settings panel of the Summary sheet. Entering a value in this field will override XPE calculations. Use this option if you have calculated this parameter by thermal simulations. You might also want to use this feature to factor out environmental parameters when analyzing power differences with another spreadsheet in which environment settings have been set differently.
