Startup power is the power required during the initial bring-up and configuration of the device. This power generally occurs over a very short period of time and thus is not a concern for thermal dissipation. However, current requirements must still be met. In most cases, the active current of an operating design will be higher and thus no changes are necessary. However, for lower-power designs where active current can be low, a higher current requirement during this time might be necessary. XPE can be used to understand this requirement. When Process is set to Maximum, the power-on current requirement for each voltage rail will be displayed in the Power Design tab if the power-on current is higher than the operating current.
