003_ac_sim : AC analysis
Requires: SmartSpice & Smartview
Minimum Versions: SMARTSPICE 3.16.12.R
The input deck uses AC analysis and several sweeps in parameter values to see response in a simple circuit. The results of the .MEASURE statement are stored in a separate output file which is distinctly separate from the RAW file.
To run the simulation, Source the deck and press the green run button. When the simulation completes, the results are shown in SmartSpice log Window.
