1. Within the DR. SPICE group, double-click on the DR. SPICE icon.

2. The figure below shows the Open dialog box, which displays a list of .CIR (circuit) files in the current project.
The Open Dialog Box
To view/open a waveform file, select waveform (.txt, .bxt, .raw) from the List of Types at the bottom left of the dialog box. By default, circuit files (files with the extension .cir) are presented. If a circuit file is selected the user has 3 options in how they wish to run the simulation: Batch, Interactive, and Streaming.
1 Batch: Batch analysis is useful when the simulation is going to be run overnight or when a long simulation must be run. Compared to Interactive and Streaming analysis modes, Batch analysis will run the fastest since the overhead of creating plot graphics is avoided. The types of analyses which will be run batch will depend on the analyses specified within the Spice deck (.TRAN, .DC, .AC, etc.). When the batch simulation begins, the DR. SPICE Status Meter will show the status of the simulation.

To run Batch analysis:
2. Interactive: Interactive analysis gives the user access to all the features of DR. SPICE. Initially the user is placed in the text editor where the user can edit the Spice deck, create the stimulus, and setup analyses. The user can then run the analyses and view waveforms, generate hardcopy, and so on. The Interactive Radio button is selected for Interactive analysis. Double-clicking on the circuit file will change the mode to interactive.
3. Streaming: Streaming analysis is useful when the user wishes to always view "streaming" or "marching" waveforms . The waveforms which are displayed are those found on the .PROBE or .PROBE/CSDF line.
As an example:
.PROBE/CSDF V([amp]) V([vcent])
.PROBE/CSDF V([fout)
will cause the waveforms to be streamed into a window with 2 Y-axes; V([amp]) and V([vcent]) will be one Y-axis while V([fout]) . will on a separate Y-axis.
The type of analysis which will be run under streaming will depend on the analyses specified within the Spice deck (.TRAN, .DC, .AC, etc.). Once the analysis is complete, DR. SPICE will leave you in interactive mode.
Select the Streaming check box for streaming analysis.
