You can perform a simulation in which the entire simulation time is not applicable to signal-activity calculation. For example, if you run a simulation for 10,000 clock cycles and reset the chip for the first 2,000 clock cycles. If the Power Analyzer performs the signal-activity calculation over all 10,000 cycles, the toggle rates are only 80% of their steady state value (because the chip is in reset for the first 20% of the simulation). In this case, you must specify the useful parts of the .vcd for power analysis. The Limit VCD Period option enables you to specify a start and end time when performing signal-activity calculations.
