EP4CE15M9I7N power supply decouple capacitor

1) Should each power supply pin connect with one 100nF decouple capacitor?

2) Due to small package, I can not place one capacitor for each power supply pin. Can the power supply pin of nearby share one 100nF capacitor as below?

Hi,


Please check this link. https://www.intel.com/content/www/us/en/programmable/support/support-resources/support-centers/board...


You can use PDN tool for the target device or use the PDN Decoupling Calculator Tool (link available on above webpage).
