MAX 7000A Programmable Logic Device Data Sheet
The parameters in this equation are:
MCTON
= Number of macrocells with the Turbo Bit option turned
on, as reported in the MAX+PLUS II Report File (.rpt)
MCDEV
= Number of macrocells in the device
MCUSED = Total number of macrocells in the design, as reported in
the Report File
fMAX
= Highest clock frequency to the device
togLC
= Average percentage of logic cells toggling at each clock
(typically 12.5%)
A, B, C
= Constants, shown in Table 31
This calculation provides an ICC estimate based on typical conditions
using a pattern of a 16-bit, loadable, enabled, up/down counter in each
LAB with no output load. Actual ICC should be verified during operation
because this measurement is sensitive to the actual pattern in the device
and the environmental operating conditions.
