Figure 31: Grouping Waveforms
Delay Measurements of Vin and Vout at 50% to 50%:
To measure delay between the input and output signals of the inverter at 50% select the tran tab
in the bottom left hand corner of the WaveView window. Group the Vout and Vin waveforms
together so the two waves overlap each other (see figure 31 on how to group signals). Open the
measurement tool by going to Tools Measurement… or by clicking in the WaveView
window. Click the All tab in the measurement tool window and fill out the options as shown
below in figure 32. Click Ok when done.
