Hi Eng Wei Thanks for the update . But I could not find any electric current rating for individual power rails from my search in the document you shared. Please tell me if you get any update on this. Best regards Ashad Anil

Hi Ashad Anil

Can you refer to Table10-1 in the document for Maximum Power Supply Current Transient?

You can also refer to power analysis features below:

Thanks Eng Wei

Thanks I have seen this line “You may observe the current transient at VCCPD only when you do not follow the recommended power-up sequence.” So If I’m setting power sequence feature, then can I get rough estimation of currents in power rails? Best Regards Ashad

Hi Ashad

You can make use the Quartus tools to generate the Early Power Estimator spreadsheet file as mentioned in the doc below:
