Figure 27: <strong>Custom</strong> <strong>Desig</strong>ner Console 3. A WaveView program window will appear which contains the graphs for the output variables you specified. 4. At the lower left corner, there are two tabs (dc and tran). Click a tab to display the respective waveform. 5. See Fig 28 for the tran tab results. 6. See Fig 29 for the dc tab results At this point, you have created a schematic cell and ran a DC and transient simulation. San Francisco State University Nano‐electronics and Computing Research Lab 28
