ICL Script Commands - Page Three

sendscript

Format: sendscript [-l] <script line>

Example: sendscript -l plot v(1)

The sendscript command sends a single line of script from IsSpice to Scope5. Multiple lines can be sent by prefixing each line with the sendscript command.
-l is a special switch used for the last plot waveform to have all waveforms rescaled and drawn with like traces.

sendscript begin identifies the following lines of script to be sent to Spice for execution. sendscript send ends the block and sends the script over. Output text is sent back to Scope5's Output Record Window

Usage in Scope5

stop - Simulation Breakpoints

Format: stop [after num] or [when condition]
stop when condition1 when condition2 ....

Example: stop when v(3) > 10
tran 1n 100n
...

When "after num" is used, the simulation will terminate after num iterations. When "when condition" is used, the simulation will terminate when the condition is true. "After num" and "when condition" cannot be used in the same stop command. The condition can use any saved vector, vector expression, and any relational operator. The condition is checked after each iteration throughout the course of the simulation.

Multiple conditions can be logically combined by using multiple stop commands or compounded when conditions. The following two examples demonstrate the AND and OR of condition1 and condition2.

AND
stop when v(3)<10 when @q1[icc]>20m
tran 1n 200n
OR
stop when v(3) > 10
stop when @q1[icc] > 20m

tf - Transfer Function

Format: tf output_nodes input_source

Example: tf V(5,3) VIN
tf I(VLOAD) VIN

Summary: The .TF statement computes the small signal ratio of the output node to the input source and the input and output impedances. Any nonlinear models, such as diodes or transistors, are first linearized based on the DC bias point, and then the small signal DC analysis is carried out.

Syntax: Output is the small signal output variable and can be any node number or name using the format v(#) or v(name). Input is the small signal input independent source.

Getting Output: tf generates output without the need for any print statement. For the first example, IsSpice4 would compute the DC transfer function ratio of V(5,3) to VIN, the input impedance looking into the circuit at VIN, and the output impedance measured across nodes 5 and 3.

timetofreq - FFT from time to frequency

Format: timetofreq vector

Example: timetofreq(current)
result = mag(current)
plot result

Performs a fourier transform from time to frequency. If the plot hasn't been initialized using fftinit, it will set a default radix of 12, or 4096 points. See also freqtotime and fftinit.

timetowave - Wavelet transform from time to wave

Format: timetowave vector

Example: timetowave v(12)

Performs a wavelet transform using a Daubuchet fourth order wave function. The vector is first interpolated into the fftinit time space so that the data has a binary radix. The transform is then done in place. See also fftinit, wavetotime and wavefilter.

wavefilter - zeros values below the limit

Format: wavefilter vector limit

Example: homecursors
constants._rms = rms(current)*.01
timetowave current
plot current
wavefilter current constants._rms
wavetotime current

All values of the vector less than the limit are set to zero. The example performs a wavelet transformation, removes the wave components that have less than 1% of the total rms contribution and inverts the transform. Wavelet filters tend to concentrate energy into fewer wave numbers (cells) than Fourier transforms for video and speech patterns. The example let’s you examine the resulting quality of the lossy compression.

wavetotime - Wavelet transform, wave to time

Format: wavetotime vector

Example: wavetotime current

Performs an inverse wavelet transform using a Daubuchet fourth order wave function. The vector is first interpolated into the fftinit time space so that the data has a binary radix. The transform is then done in place. See also fftinit, wavefilter and timetowave.

tran - transient analysis

Format: tran tstep tstop [tstart [tmax] ] [uic]

Example: tran 50ns 1us
tran 10n 10u 9U 1n uic

Summary: The transient analysis computes the circuit response as a function of time over a user-specified time interval. The initial conditions are normally determined by a DC analysis called the initial transient solution. The UIC option can be set to allow the simulation to begin from a user specified state. This statement is generated using the simulation setup dialog in the schematic editor, actions menu. See IsSpice4 help for additional information.

unalias - destroy an alias

Format: unalias string

Example: unalias vout

Removes the alias.

unlet - destroy a vector

Format: unlet vector

Example: unlet sp

Removes the specified vector, see also let.

Format: unset variable name

Example: unset units
unset myvar0

Clears the value of the specified variable created by set.

version - print version information

Format: version

Example: version

Print the version number and the creation date of the executable.

view - generate real time display

Format: view analysis vector or name
+ [min] [max] [= expression]

Example: view dc v(8)
view tran v(8) 0 5
view tran gain 0 10 = 20 * log(v(8)/v(1))
view ac out = sqrt(real(v(8))^2 + imag(v(8))^2)

Produces a graph of the specified waveform without saving tabular data in the output file. Analysis must be specified. Vector can be any saved vector or vector created with expression. Scaling is done with the min and max values. Expression can be any vector expression. All vectors in expression must be saved (save/.PRINT statements) prior to the occurrence of expression. The graph is displayed in the Simulation Status window.

where - identify a problem node

Format: where

Example: where

For transient and operating point analyses the name of the last node or device to cause non-convergence is saved and printed. This command can be performed at any time during a simulation. Note: Only one node or device is printed; there may be problems with more than one.

while - control loop

Format: while condition
commands
end

Example: op
while v(6) < 2.6 & @q1[icc] > 10m
alter @r16[resistance]=@r16[resistance]+10
op
end

Note: Condition can be enclosed in parenthesis.

The while command performs the commands within the defined loop until the condition is evaluated as true. The while loop will test the condition before the loop is processed. Therefore, it is necessary to save and generate the vectors used in the condition prior to reaching the loop. Notice above that an analysis is performed prior to entering the control loop. This allows v(3) and q1[icc] to be initialized. Dowhile test the condition at the end of the loop. See also repeat.

write - write data to a file

Format: write file_name vectors [expressions]

Example: write tmp v(3) v(3)*v(4)
write myfile
write %icapsdir%in\rule.plt

Note: Condition can be enclosed in parenthesis.

Writes the data for the given expressions to the file specified.

Vectors to be written are grouped together by plots. Hence, if the expression list contained three vectors from one plot and two from another, then two plots will be written. One containing three vectors and one containing two vectors. If the scale for a vector is not present it is automatically written out. The file_name can have an environment variable specified between % characters. The system environment is searched first, if nothing is present then the user environment is searched. see the set command to establish a user environment.

Use the load command to view the data you have written.

The default format is a standard text file. However, the variable filetype can be set to override the default. If no expression list is given all vectors will be written to the file. Filetypes recognized are binary, ascii (the default) and oct.

- This symbol indicates that the script command is also used in IntuScope 5.

set - change a simulation variable
Format:	set [word] [word = value]
Example:	set temp=125 set units=degrees
Set changes the value of the word given. Use unset to remove the word. If no value is given then the word is set to true. The value of word can be used in any ICL command by writing $word. In addition to all of the .OPTIONS parameters, the following variables have meaning:

Optionally, data on a specific set of model parameters can requested after the colon. Model information within a subcircuit can be tabulated by placing the subcircuit reference designation, within colons, on the command line (letter:name:) For example, "showmod q1:x3: " will produce information about q1 in subcircuit x3. See IsSpice4 help, Appendix B for a complete list of model parameters

sort - sort vectors
Format:	sort [-na \| -nd \| -va \| -vd]
Example:	sort -na sort -vd
Sorts the current plot by name, -na or -nd, or by value, -va or -vd. The sort can be in ascending, -na and -va or descending order, -nd or -vd.

status - display breakpoint and vector information
Format:	status
Displays all of the currently saved vectors and breakpoints.

step - run a fixed number of timepoints
Format:	step [n]
Example:	step 50
Iterates the simulation n number times, or once and stops.

stop - Simulation Breakpoints
Format:	stop [after num] or [when condition] stop when condition1 when condition2 ....
Example:	stop when v(3) > 10 tran 1n 100n ...
When "after num" is used, the simulation will terminate after num iterations. When "when condition" is used, the simulation will terminate when the condition is true. "After num" and "when condition" cannot be used in the same stop command. The condition can use any saved vector, vector expression, and any relational operator. The condition is checked after each iteration throughout the course of the simulation. Multiple conditions can be logically combined by using multiple stop commands or compounded when conditions. The following two examples demonstrate the AND and OR of condition1 and condition2.
	AND stop when v(3)<10 when @q1[icc]>20m tran 1n 200n OR stop when v(3) > 10 stop when @q1[icc] > 20m tran 1n 200n

switch - make another process active
Format:	switch [edit] or [scope] or [net]
Example:	switch net
Make one of these processes active:
	edit (text editor), scope (post processor), net (schematic editor)

tf - Transfer Function
Format:	tf output_nodes input_source
Example:	tf V(5,3) VIN tf I(VLOAD) VIN
Summary: The .TF statement computes the small signal ratio of the output node to the input source and the input and output impedances. Any nonlinear models, such as diodes or transistors, are first linearized based on the DC bias point, and then the small signal DC analysis is carried out.
Syntax: Output is the small signal output variable and can be any node number or name using the format v(#) or v(name). Input is the small signal input independent source.
Getting Output: tf generates output without the need for any print statement. For the first example, IsSpice4 would compute the DC transfer function ratio of V(5,3) to VIN, the input impedance looking into the circuit at VIN, and the output impedance measured across nodes 5 and 3.

timetofreq - FFT from time to frequency
Format:	timetofreq vector
Example:	timetofreq(current) result = mag(current) plot result
Performs a fourier transform from time to frequency. If the plot hasn't been initialized using fftinit, it will set a default radix of 12, or 4096 points. See also freqtotime and fftinit.

timetowave - Wavelet transform from time to wave
Format:	timetowave vector
Example:	timetowave v(12)
Performs a wavelet transform using a Daubuchet fourth order wave function. The vector is first interpolated into the fftinit time space so that the data has a binary radix. The transform is then done in place. See also fftinit, wavetotime and wavefilter.

wavefilter - zeros values below the limit
Format:	wavefilter vector limit
Example:	homecursors constants._rms = rms(current)*.01 timetowave current plot current wavefilter current constants._rms wavetotime current
All values of the vector less than the limit are set to zero. The example performs a wavelet transformation, removes the wave components that have less than 1% of the total rms contribution and inverts the transform. Wavelet filters tend to concentrate energy into fewer wave numbers (cells) than Fourier transforms for video and speech patterns. The example let’s you examine the resulting quality of the lossy compression.
