<h2>LogicSim Manual</h2>
|
|
|
|
<p>Select circuits from the list on the left side and place them on the work panel.</p>
|
|
<p>To connect click on an output of a circuit (right side) and draw the wire to an input of a circuit.
|
|
Hold down shift while clicking somewhere on a wire to connect a new wire to this point.</p>
|
|
<p>Circuits and Wires can be activated by clicking on them and then deleted with the DEL key.</p>
|
|
<p>You can change settings on some circuts (clock, MonoFlop, LCD, TextLabel) by selecting "Properties" in their
|
|
context-menus.
|
|
<br><br>
|
|
|
|
<p>It is possible to change the number of inputs for some circuits (AND, OR, XOR, etc) with combo box
|
|
below the circuits list. These circuits act as they were connected like this:</p>

|
|
<p>With the "input inverter" you can invert the level of a wire at the input of a circuit.
|
|
To place the inverter, select it from the list and click on a circuit input.</p>
|
|
<p>An input can be set to a defined level by using "input high" and "input low", without having to connect
|
|
a wire to it.</p>
|
|
<p>To reset an input to normal behaviour, use "normal input" on it.

<h4>Module Creation</h4>
|
|
<p>A module contains a complete LogicSim circuit system that can be used as a single circuit element.</p>
|
|
<p>Select "Create Module" from the "Module" menu. Enter the module description in
|
|
the appearing dialog. "Module Name" is the filename under wich the module is saved later, "Module Label" is
|
|
the label on the module symbol.</p>
|
|
<p>After pressing the "Use" button an "input" and an "output" circuit will appear. These represent the module in/outputs.
|
|
Connect your circuit to them. You can connect Switches to the "INPUT" and LED's to the "OUTPUT" element to test the module.</p>
|
|
<p>After saving the module using the save button, it will appear in the circuits list and can be used in
|
|
a new circuit.</p>
|
|
<p>Open "FullAdder.mod" from the "modules" directory for an example. This module is used in the "5 Bit Adder.lsim" circuit.</p>
