device. Decoupling capacitors were not used in this measurement. To
factor in the current for decoupling capacitors, sum up the current for
each capacitor using the following equation:
I = C (dV/dt)
If the regulator or power supply minimum output current is more than
the Stratix device requires, then the device may consume more current
than the maximum current listed in
not require any more current to successfully power up than what is listed
in
The exact amount of current consumed varies according to the process,
temperature, and power ramp rate. Stratix devices typically require less
current during power up than shown in
current during device operation is generally higher than the power-up
current.
