Table 8. Recommended Operating Conditions for Intel MAX 10 Devices in Intel MAX10 FPGA Devices has a description of tRAMP (Power supply ramp time), and Minimum is not specified, but Note (7) has the following description.
"There is no absolute minimum value for the ramp time requirement. Intel characterized the minimum ramp time at 200 us."
Is 200us (Minimum) a required value as a recommendation?
The Ramp Rate of the 2.5V power supply device is currently 100us (Typical), and it is necessary to confirm whether it can be adopted or not.
