Menus: ~
This is the Main Menu for the PSpice Control Shell. ~
Use the Files Menu to specify the current file to be read or
to edit the file. ~
Use the Circuit Menu to display and modify devices in the circuit
and to change model parameters. ~
Use the Analysis Menu to set up parameters for the different
analysis types, then select 'Run PSpice' to run the enabled analyses. ~
Use the Probe Menu to view the results of the analyses. ~ ~
Function Keys: ~
At any time the F1 key will provide help. Hit the F1 key
a second time to exit help. ~
The F2 key allows you to move and/or resize most of the
pop up windows (like this one). If the current window is moveable
or resizable you may press F2 and instructions will appear at the
bottom of the page explaining how to move and resize the window. ~
The F3 key calls up the On-Line Manual.
When you are in the editor just hit F3 then Enter twice and you will
get the manual page that describes the device or command on the line
you are currently editing ("context-sensitive help"). ~
The F4 key shows a list of choices where possible - for example, file
names with a ".cir" extension ~
The F5 key pops up the PSpice calculator. ~
The F6 key shows you a list of errors in the current output file. ~ ~
Using the Mouse: ~
Moving the mouse left/right/up/down is equivalent to using the
arrow keys. ~
Clicking the left or right mouse button is the
same as Enter (except in the editor, where this turns on marking). ~
Clicking both buttons together is the same as ESC.

Floating nodes have no DC path to ground. Frequent causes of trouble: ~ ~
The two ends of a transmission line do not have a DC connection between
them. ~
Voltage-controlled sources do not have a DC connection between their
controlling nodes. ~ ~
There is an error in the circuit description. ~ ~
Assuming the circuit is correct, the solution is to connect the
floating node to ground via a large-value resistor.
@@MANHL
PSpice checks for zero-resistance loops. These may be caused by
independent voltage sources (V), controlled voltage sources (E and H),
and inductors (L); or there may be an error in the circuit description. ~
Assuming the circuit to be correct, the solution is to add series
resistance into the loop.
@@MANHC
Convergence problems may occur in the DC sweep, bias point calculations
and transient analysis. ~ ~
DC Sweep: most frequent problem is attempting to analyze circuits
with regenerative feedback (eg. Schmitt trigger). Try doing a
Transient Analysis instead of the DC Sweep. Use a piecewise-linear
voltage source to generate a slow ramp. You can sweep up and down
again in the same analysis. ~ ~
Bias Point: use the .NODESET statement to help PSpice find a solution.
Nodes such as the outputs of opamps are good candidates for .NODESET. ~ ~
Transient Analysis: unrealistic modelling of circuits with switches
but no parasitic capacitance can cause problems, for example circuits
containing diodes and inductors but no parasitic resistance or capacitance. ~
It may be necessary to relax RELTOL from .001 to .01. ~
Using the "uic" modifier causes the Transient Bias Point calculation to
be skipped, causing Transient Analysis convergence problems. Use .IC
or .NODESET instead. ~
With high voltages and currents, it may be necessary to increase VNTOL
and ABSTOL. For voltages in the kV range raise VNTOL to 1mV. For currents
in the amps range raise ABSTOL to 1nA. For currents in the kA range
raise ABSTOL to 1uA.
@@MANHA
PSpice's accuracy is controlled by the RELTOL, VNTOL, ABSTOL and
CHGTOL parameters of the .OPTIONS statement. ~
The most important is RELTOL, which controls the relative accuracy
of all voltages and currents that are calculated. RELTOL defaults to 0.1%. ~
VNTOL sets best accuracy for voltages. ABSTOL sets best accuracy for
currents. CHGTOL sets best accuracy for charge/flux.
@@MANHG
Global nodes begin with the prefix "$G_". ~
Examples: $G_VCC $G_COMMON. ~
Predefined digital nodes are: $D_HI, $D_LO, $D_NC, $D_X.
@@MANEE
PSpice will accept expressions in most places where a numeric
value is required. This includes component values, model parameter
values, subcircuit parameters, initial conditions, etc. ~
An expression is contained within {} and must fit on one line.
Components of an expression include: numbers, operators +-*/,
parameter names and functions (sin, cos, exp, etc). For example,
a resistor value could be defined in terms of a global parameter RSHEET: ~
re1 20 21 {rsheet * 1.10} ~
Expressions may be used for global parameter values, but these
expressions may not contain parameter names. ~
Expressions used in the extended controlled sources may additionally
refer to node voltages, currents, and the swept variable "time".
@@MANEG
Global parameters are defined with the .PARAM statement. They can
then be used in expressions for device values, etc. Example: ~
.param pi=3.14159265 ~
c1 2 0 { 1 / (2 * pi * 10khz * 10k) } ~
@@MANES
Subcircuit parameters supply default values for subcircuits. The
defaults can be overridden when the subcircuit is called. The values
given to subcircuit parameters can be expressions. In addition to the
normal components of an expression, subcircuit parameter expressions
may refer to the names of a subcircuit's own parameters (if any). ~
If a global parameter and a subcircuit parameter have the same name,
the subcircuit parameter definition is used. ~ ~
For example, here is the definition of a parasitic node: ~ ~
.subckt para 1 params: r=1meg, c=1pf ~
r1 1 0 {r} ~
c1 1 0 {c} ~
.ends ~ ~
and here is the subcircuit being used: ~
xpara1 27 para params: c=5pf
