Once the schematic is complete, the next step is to create a simulation profile.
If the user has created a simulation profile in PSpiceĀ®-for-TI before skip forward to Section 5.1.
To create a new simulation profile, navigate to PSpice > New Simulation Profile or through the new simulation profile icon in the taskbar shown in Figure 5-1.
Name the simulation profile a representative name for ease of recognition. In Figure 5-2, the simulation is named ac to stand for an AC sweep. Select Create to continue.
In the example, the analysis is done in the frequency domain; as a result, an AC Sweep/Noise is selected as the Analysis Type in the Analysis tab. The frequencies of interest depend on the bandwidth of the amplifier, in the example a frequency sweep from 10Hz to 100MHz is run with 10 points per decade. PSpiceĀ®-for-TI requires the declaration of MEG for mega (106), M is recognized as milli (10-3). Select Apply to save the settings on this tab.
In the Probe Window tab, select to show Last Plot every time the simulation is run. The resulting factor is that the simulation profile saves the setup (plots and equations) in the probe window and is applied on every run. Select Apply and OK to exit simulation profile settings.
