I
I
can be estimated for the ispLSI and pLSI 1032 using the following equation:
= 52 + (# of PTs * 0.30) + (# of nets * Max. freq * 0.009) where:
CC
CC
# 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
The I
estimate is based on typical conditions (V
= 5.0V, room temperature) and an assumption of 2 GLB loads on
CC
CC
average exists. These values are for estimates only. Since the value of I
program in the device, the actual I
is sensitive to operating conditions and the
CC
should be verified.
