Power consumption in the ispLSI and pLSI 1032E device
depends on two primary factors: the speed at which the
device is operating, and the number of product terms

Power Consumption
(mA) = 15 + (# of PTs * 0.59) + (# of nets * Max freq * 0.0078)
can be estimated for the ispLSI and pLSI 1032E using the following equation:
# of PTs = Number of Product Terms used in design
# of nets = Number of Signals used in device
Max freq = Highest Clock Frequency to the device (in MHz)
CC
estimate is based on typical conditions (V CC = 5.0V, room temperature) and an assumption of four GLB
