Hardwire: Power consumption?


Record #1965

Problem Title:
Hardwire: Power consumption?


Problem Description:
Keywords: HardWire, power

Urgency: Standard

General Description:  What is the general rule of power
consumption between a FPGA and a Hardwire device?


Solution 1:

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.
