Rise Transition Time Figure 6-29: Cell Fall Delay Measurement The time taken for the output to reach from 10% of its final value to 90% of its final value is defined as the rise transition time. Figure 6-30 below shows the rise transition time measurement waveform. Figure 6-30: Rise Time Measurement Waveform 112
Fall Transition Time The time taken for the output to reach from 90% of its final value to 10% of its final value is termed the fall transition time. Figure 6-31 below shows the fall transition time measurement waveform. Leakage Power during ON State Figure 6-31: Fall Time Measurement Waveform The ON-state leakage power is measured after the input has transitioned to a logic high value and is in its steady state. Leakage Power during OFF State The OFF-state leakage power is measured after the input has transitioned to a logic low value and is in its steady state. 113
