Voltage source
This sets the source’s voltage to the sweep value during the sweep.
In the Name text box, type a reference designator of an independent voltage source, such as VI.
Current source
This sets the source’s current to the sweep value during the sweep.
In the Name text box, type the name of an independent current source.
Global parameter
This sets the value to the sweep value and all expressions are re-evaluated.
In the Parameter name text box, type a global parameter name.
Model parameter
This sets the parameter in the model to the sweep value.
From the Model type list, select a model type. In the Model Name text box, type the model name. In the Parameter name text box, type a parameter name.
Temperature
This sets the temperature to the sweep value. For each value in the sweep, the model parameters of all the circuit components are updated to that temperature.
Linear
Indicates a linear sweep. The swept variable is swept linearly from the starting to the ending value. The Increment value is the step size.
Octave
Indicates sweep by octaves. The sweep variable is swept logarithmically by octaves.
Decade
Indicates sweep by decades. The sweep variable is swept logarithmically by decades.
Value list
Uses a list of values. In this case, there are no start and end values. Instead, the numbers you type in the Values List text box are the values that the sweep variable is set to.
YMAX
Finds the greatest difference in each waveform from the nominal run.
MAX
Finds the maximum value of each waveform.
MIN
Finds the minimum value of each waveform.
RISE_EDGE
Finds the first occurrence of the waveform crossing above the threshold value. Type a threshold value in the Threshold value text box.
FALL_EDGE
Finds the first occurrence of the waveform crossing below the threshold value. Type a threshold value in the Threshold value text box.
Low
Specifies the lower limit of the range over which the function is evaluated.
Hi
Specifies the upper limit of the range over which the function is evaluated.
None
Forces the nominal run to produce output.
All
Forces all output to be generated, including the nominal run.
First
Generates output only during the first n runs. Type the value for n in the Runs text box.
Every
Generates output every nth run. Type the value for n in the Runs text box.
Runs
Performs an analysis and generates output only for listed runs. Up to 25 values can be specified in the Runs text box. Prints out at the beginning of each run the model parameter values actually used for each component during that run.
Random number seed
Defines the seed for the random number generator within the Monte Carlo analysis. You must type an odd integer ranging from 1 to 32767. If the seed value is not set, it defaults to 17533.
Output All
Requests output from the sensitivity runs, after the first run. The sensitivity and worst case runs are done with variations on model parameters as specified by the DEV and LOT tolerances. The default is to vary by BOTH.
Vary both DEV and LOT, Vary DEV, Vary LOT
Vary DEV and Vary LOT limit the devices analyzed to only the device types that have a DEV tolerance or a LOT tolerance.
Vary both DEV and LOT includes all the device types in the analysis.
Limit devices to type(s)
In the text box, type a list of the specific device types you want included in the analysis. The list is a string containing the initial letters of PSpice primitives.
Primary Sweep value
The first DC sweep value at which the bias point is to be saved. If there is only one sweep value, type a value in the Primary Sweep value text box. If there are two sweep variables, then Primary Sweep value specifies the first sweep value.
Secondary Sweep value
The second DC sweep value at which the bias point is to be saved. If there is only one sweep value, type a value in the Primary Sweep value text box. If there are two sweep variables, then Secondary Sweep value specifies the second sweep value.
Parametric Sweep value
The step value at which the bias point is to be saved for parametric analyses.
Number of runs
The number of the Monte Carlo or worst case analyses run for which the bias point is to be saved.
Use distribution
This option is the default distribution for Monte Carlo deviations.
From the list, select Uniform or Gaussian, or click the Distributions button to enter your own distribution.
Initialize flip-flops to X, 0, or 1
If set to X, all flip-flops and latches produce an X (unknown state) until explicitly set or cleared, or until a known state is clocked in.
If set to 0, all such devices are cleared.
If set to 1, all such devices are preset.
default propagation delay mode
You can change the mode for an individual part in your design by changing the part’s MNTYMXDLY property. By default, this part value is set to 0, which tells PSpice to use the default value set in the Options tab.
Temperature Sweep temperature
Defines the temperature at which the bias point is to be saved for temperature analyses.
Include detailed bias point information for nonlinear controlled sources and semiconductors
This option saves the small-signal (linearized) parameters of all the nonlinear controlled sources and all the semiconductor devices to the output file.
This is equivalent to the .OP (bias point) PSpice circuit file command.
Perform Sensitivity analysis
In the Output Variable(s) text box, type
This option is equivalent to the .SENS (DC sensitivity) PSpice circuit file command.
Calculate small-signal DC gain
This option calculates the small-signal DC gain by linearizing the circuit around the bias point.
In the From Input Source Name text box, type
In the To Output Variable text box, type
This option is equivalent to the .TF (small-signal DC transfer function) PSpice circuit file command.
Data collection parameters
Text Data File Format (CSDF)
Select the Save data in the CSDF format (.CSD) option to write Probe data in text format rather than binary format. This option is not available if the Run Probe During Simulation option is used.
