Package Thermal Characteristics
The power dissipated by an FPGA application has implica-
tions on package selection and system design. The power
consumed by a Spartan-3E FPGA is reported using either
the
integrated in the Xilinx ISE® development software.

of power consumption. The junction-to-board (θ
similarly reports the difference between the board and junc-
tion temperature. The junction-to-ambient (θ
reports the temperature difference per watt between the
ambient environment and the junction temperature. The θ
value is reported at different air velocities, measured in lin-
ear feet per minute (LFM). The “Still Air (0 LFM)” column
shows the θ
resistance drops with increasing air flow.
