operation because this measurement is sensitive to the actual pattern in
the device and the environmental operating conditions.
To better reflect actual designs, the power model (and the constant K in
the power calculation equations) for continuous interconnect ACEX 1K
devices assumes that LEs drive FastTrack Interconnect channels. In
contrast, the power model of segmented FPGAs assumes that all LEs
drive only one short interconnect segment. This assumption may lead to
inaccurate results when compared to measured power consumption for
actual designs in segmented FPGAs.
