PowePlay. I/O power and core static power

I'm trying to understand how PowerPlay works. I use Quartus 10.1 sp1. I have two projects (A and B) that execute exactly the same task. These projects are implemented on the same F...

Hi, i believe the static power different between project A and B might due to the different of internal structure of both project.

Static power is mostly a function of how many transistors need to maintain their state as well as circuit design. The FPGA static power is proportional to the static current ICC, the current that flows regardless of gate switching (transistor is ON “biased” or OFF “unbiased”).
