55 / 64 page Altera Corporation 55 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. Table 31.
