FLEX 10K Embedded Programmable Logic Device Family Data Sheet
fMAX
=
Maximum operating frequency in MHz
N
=
Total number of logic cells used in the device
togLC
=
Average percent of logic cells toggling at each clock
(typically 12.5%)
K
=
Constant, shown in Tables 114 and 115
This calculation provides an ICC estimate based on typical conditions with
no output load. The actual ICC should be verified during 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 FLEX
devices assumes that logic cells drive FastTrack Interconnect channels. In
contrast, the power model of segmented FPGAs assumes that all logic
cells drive only one short interconnect segment. This assumption may
lead to inaccurate results, compared to measured power consumption for
an actual design in a segmented interconnect FPGA.
Figure 32 shows the relationship between the current and operating
frequency of FLEX 10K devices.
