Power Estimation and Management
Lattice Semiconductor
for LatticeECP/EC and LatticeXP Devices
Power Calculator – Total Power
The Power Calculator project created or opened using any of the methods discussed here would allow a user to
calculate the power consumption for the device running with their design.
The estimated power is indicated in the Total section at the bottom of the table as shown in Figure 12-18.
Figure 12-18. Calculated Power in the Power Calculator Main Window
The second and third columns from the left indicate the DC (or static) and AC (or dynamic) power consumption.
The total power consumption for the design can be seen in the same table. Scroll down to the row labeled Total.
Activity Factor
Activity Factor % (or AF%) is defined as the percentage of frequency (or time) that a signal is active or toggling of
the output.
Most of the resources associated with a clock domain are running or toggling at some percentage of the frequency
at which the clock is running. Users are required to provide this value as a percentage under the AF% column in
the Power Calculator tool.
