i wanted to know the Difference between ASICS and FPGA
in terms of power .........
is FPGA requires less power compare to ASICS .......
can i get some doc related to power difference between FPGA and ASICS....

maybe fpga requires less power because allteh pins are user defined and all the pins are not usuaalyy used
