SIN 1
Sinusoidal (SIN) Stimulus
The SIN form causes the current or voltage to start at <ioff/voff> and stay
there for <td> seconds. Then, the current or voltage becomes an exponentially
dampled sine wave described by this formula:
voff + vampl * sin( 2pi * ( freq * (TIME-td) -phase/360))*e-(TIME-td)*df
Parameters Units Default
---------- ----- -------
<ioff/voff> offset current/voltage amp/volt none
<iampl/vampl> peak amplitude of current/voltage amp/volt none
<freq> frequency Hertz 1/TSTOP
<td> delay sec 0
<df> damping factor 1/sec 0
<phase> phase degree 0
An '*' in front of a parameter name indicates that the default value for
the parameter is being used.
DGEDIT 1
The transient specification for a digital stimulus consists
of a series of "commands" that describe the output of the
stimulus over time. If the topmost command has a '+' in
front of it, there are more commands before it that are not
being displayed. If the bottommost command has a '+' in
front of it, there are more commands after it that are not
being displayed. To see commands that are not being
displayed, use the Modify_command command.
Add_command displays a menu of the available commands that
can be used to define the stimulus.
The SET command prompts you to enter a <time> and a <value>.
At the given <time>, the output of the stimulus changes to
<value>. The format of <value> depends on the "radix" of
the stimulus. When you have entered all the SET commands
you want, press <Esc> to return to the menu of commands.
The GOTO N TIMES command prompts you to enter a <time>, a
<label name> and the number of times you want to repeat the
loop. When the "goto" is encountered, the statement
following the <label name> is immediately executed.
The GOTO UNTIL GE/GT/LT/LE commands prompt you to enter a
<time>, a <label name> and a <value>. The "goto" is done
until the value of the stimulus is GE (greater than or
equal), GT (greater than), LT (less than ) or LE ( less than
or equal to ) the value specified. This command only
appears if the stimulus has more than one output node.
The INCR BY command prompts you for a <time> and a <value>.
The output of the stimulus is incremented by <value> each
time this command is executed.This command only appears if
the stimulus has more than one output node.
The DECR BY command prompts you for a <time> and a <value>.
The output of the stimulus is decremented by <value> each
time this command is executed. This command only appears if
the stimulus has more than one output node.
The LABEL command prompts you for a label name. This allows
you to define the labels that are used in "goto" commands.
