Command Summary

*

Comment line.

!

Pass a command to the operating system.

<

Batch mode.

>

Direct the ``standard output'' to a file.

AC

Performs a small signal AC (frequency domain) analysis. Sweeps frequency.

ALARM

Select points in circuit check against limits.

ALTER

Perform analyses in queue. Changes follow. (Not implemented.)

BUILD

Build a new circuit or change an existing one.

CHDIR

Change current directory.

CLEAR

Delete the entire circuit, titles, etc.

DC

Performs a nonlinear DC analysis, for determining transfer characteristics. Sweeps DC input or component values.

DELETE

Delete a part, or group of parts.

DISTO

SPICE command not implemented.

EDIT

Edit the circuit description using your editor.

END

Perform analyses in queue. New circuit follows. (Implemented incorrectly.)

EXIT

Exits the program. (Same as quit.)

FANOUT

List by node number, the branches that connect to each node.

FAULT

Temporarily change a component.

FOURIER

Transient analysis, with results in frequency domain. (Different from SPICE.)

GENERATOR

View and set the transient analysis function generator.

GET

Get a circuit from a disk file. Deletes old one first.

IC

Set transient analysis initial conditions. (Not implemented.)

INCLUDE

Include a file from disk. Add it the what is already in memory.

INSERT

Insert a node number. (Make a gap.)

LIST

List the circuit on the console.

LOG

Save a record of commands.

MARK

Mark this time point, so transient analysis will restart here.

MERGE

Get a file from disk. Add it the what is already in memory.

MODIFY

Change a value, node, etc. For very simple changes.

NODESET

Preset node voltages, to assist convergence. (Not implemented.)

NOISE

SPICE command not implemented.

OP

Performs a nonlinear DC analysis, for determining quiescent operating conditions. Sweeps temperature.

OPTIONS

View and set system options. (Same as set.)

PAUSE

Wait for key hit, while in batch mode.

PLOT

Select points in circuit (and their range) to plot.

PRINT

Select which points in the circuit to print as table.

QUIT

Exits the program. (Same as exit.)

SAVE

Save the circuit in a file.

SENS

SPICE command not implemented.

STATUS

Display resource usage, etc.

SWEEP

Sweep a component. (Loop function.)

TEMP

SPICE command not implemented.

TF

SPICE command not implemented.

TITLE

View and create the heading line for printouts and files.

TRANSIENT

Performs a nonlinear transient (time domain) analysis. Sweeps time.

UNFAULT

Undo faults.

UNMARK

Undo mark. Release transient start point.

WIDTH

Set output width.
