Run a Simulation
The purpose of adjusting the input
Before going any further, you must first understand what is meant by "adjusting
the input." In a DC or AC step analysis, this would mean changing the voltage
or frequency used to calculate each element's state. In a transient analysis,
this would mean changing the time iteration from which each state is calculated.
Any change in the input has a ripple effect through the entire circuit and can
possibly affect the state of every element. The whole idea of MoHAT is to slow
this process down and allow you to make this change one microvolt or nanoamp
at a time. The smallest iteration or step you can make is determined by the
PSpice "increment" value in a DC analysis, the "points"
value in an AC analysis, or by the "print_step" in a transient analysis.
How to adjust the input
The controls to adjust the input of your circuit are located in the upper left
corner of the screen above the controls menu. At the top of the controls is
a text box indicating which voltage, frequency, or time iteration is currently
displayed by the circuit. Below that is a slider bar with arrows on either end.
The donut-shaped slider displays the relative location of the currently displayed
input, with the left side being the first of the input and the right side being
the last of the input. You can click on the donut-shaped slider and drag it
left or right to make big adjustments to the input, or you can click on either
of the arrow buttons to make single step adjustments. Any adjustments you make
are reflected in the text box above, showing you exactly what the new input
is.
The other way to adjust the input is to allow the circuit to automatically
step through each input in a timed sequence. This allows you to sit back and
watch each element change, beginning with the first of the input to the last.
To start "playing" the circuit from the current input, press the play
button, which has an arrow on it. If at any time you want to pause the simulation
or stop it from playing, press the stop button which has the square on
it. The simulation will automatically stop when it reaches the last of the input.
To adjust the speed at which the simulation steps through each input, use the
slider located below the play and stop buttons. Move the slider toward the turtle
to slow down the simulation or toward the rabbit to speed it up.
