Would higher temperatures cause the power up current to reach the standby current level at a faster rate in Stratix® II and Cyclone® II devices?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

No, the higher temperature will slow down the ramp rate (dv/dt) and therefore it will take longer to reach the standby current level.  The amount of delay will depend on the degree of temperature and the total bulk capacitance which is seen in the power distribution network. The equation Ic=C*dv/dt describes the in rush current that will charge the bulk capacitance during power-up.
