Hi,

I am using DC to sweep an inverter to see what regions are the transistors at. In DC analysis, I selected save DC operatin point, and sweep the input voltage from 0 to 1.2v
After DC simulation, I use results -> print -> DC operating points to print the results. But after I select one transistor, why there is only one voltage point printed, not a range from 0 to 1.2? How can I get a group of points?


Thank you!

If you print the operating point (OP) values, you always get the results of the start point of your sweep, here Vgs=0V. So if you want reasonable printed values (which also can be backannotated into the schematic), use a fixed, reasonable OP.

Should you want to present any swept OP values, use the plot facility (via the calculator).
