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-3 FPGA is reported using either

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
