Analyses and output
.op .dc .ac .tran .tf .pz .noise .disto .sens, output control, .meas, .step and .optimise.
The following command lines are for specifying analyses or plots within the circuit description file. Parallel commands exist in the interactive command interpreter (detailed in the following section). Specifying analyses and plots (or tables) in the input file is useful for batch runs. Batch mode is entered when either the -b option is given or when the default input source is redirected from a file. In batch mode, the analyses specified by the control lines in the input file (e.g. ".ac", ".tran", etc.) are immediately executed (unless ".control" lines exists; see the section on the interactive command interpretor). If the -r rawfile option is given then all data generated is written to a Spice3 rawfile. The rawfile may be read into an interactive Spice3f5 session with the load command. In this case, the .SAVE line (see below) may be used to record the value of internal device variables (see Appendix B).
If a rawfile is not specified, then output plots (in "line-printer" form) and tables can be printed according to the .PRINT, .PLOT, and .FOUR control lines, described next. .PLOT, .PRINT, and .FOUR lines are meant for compatibility with Spice2.
