Hardwire: Power consumption?

Description


General Description: What is the general rule of power

consumption between a FPGA and a Hardwire device?

Solution


The power consumption is typically slightly less (10%)

compared to that of a FPGA. However, the power differences

are *VERY* design dependent. If most power is used in I/O

switching in the FPGA, then there is very little power

difference between the FPGA and the HardWire device. If most

of the power is in the logic, then there is a larger power

reduction. Currently, Xilinx doesn't have a software tool to

predict the difference.
