I am using a 10CL006ZU256I7G FPGA. “I don’t need to use all of the banks in the U256 package. What is the most power efficient way to not use an entire bank?”

Hi, You can use the Quartus setting Quartus II software -> assignments -> settings -> devices -> unused pins. To make the unused pin connection. Better to connect to gnd. And also follow the recommendation from pin connection guideline https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/cyclone-10/pcg-01021.pdf

RSree, Thanks you for your answer. What should I do with the VCCIO for the unused banks? Connect it to gnd, 1.8V, ????? Thanks for your assistance, Bill

Hi , The VCCIO has to connect to required voltage. For unused banks the PCG does nor recommend to connect to GND. Connect to the voltage mentioned as per the guidelines in page no:9 https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/cyclone-10/pcg-01021.pdf
