ICC vs. Frequency
The selected “typical” pattern utilized 50% of the device resources. Half of the macrocells were programmed as registered, and
the other half were programmed as combinatorial. Half of the available product terms were used for each macrocell. On any
vector, half of the outputs were switching.
By utilizing 50% of the device, a midpoint is defined for ICC. From this midpoint, a designer may scale the ICC graphs up or down to
estimate the ICC requirements for a particular design.
