Defining stimuli 1. Place stimulus part instances from the symbol set: VSTIM, ISTIM and DIGSTIMn (found in the SOURCSTM.OLB part library). 2. Click the source instance to select it. 3. From the Edit menu, choose PSpice Stimulus to start the Stimulus Editor. 4. Fill in the transient specification according to the dialogs and prompts. Piecewise linear and digital stimuli can be specified by direct manipulation of the input waveform display. 5. From the File menu, choose Save to save the edits. 6. Click Yes to update the schematic. See Chapter 14, "Digital simulation," for detailed information about creating digital stimuli. Example: piecewise linear stimulus 1. Open an existing schematic or start a new one. 2. From the Place menu, choose Part and browse the SOURCSTM.OLB part library file for VSTIM (and select it). 3. Place the part. It looks like a regular voltage source with an implementation property displayed. 4. Click the implementation label and type Vfirst. This names the stimulus that you are going to create. 5. If you are working in a new schematic, choose Save from the File menu. This schematic save step is necessary since the schematic name is used to create the default stimulus file name. 6. Click the VSTIM part to select it.
