2.2 Starting LogicWorks 4 on your laptop
After you start LogicWorks 4, you should see a tool palette, a simulation palette, a schematic
circuit and symbol editor window, a timing diagram window, and a device library palette.
2.3 Obtaining and placing gates in schematic window
On the device library palette, choose “Simulation Gate.clf” with the left mouse button. Find two-
input AND gate, AND-2. Double click the left mouse button to pick AND-2. Move the cursor to
the schematic window. Press one of the four arrow keys on the keyboard to change orientation of
the device.
Each time the left mouse button is pressed a copy of the chosen device is placed on the schematic
window. Click the right mouse button to drop the device.
Do the same for two-input OR gates OR-2 and inverters that is denoted NOT gate in the library.
You can rearrange the gate positions by picking one up and dragging it with the left mouse
button.
You can copy a gate by choosing it and choosing Edit->Copy (Control-C) and then Pasting it.
2.4 Connecting gates
To connect two pins with a wire, select the end of one pin with left mouse button and pressing
and dragging the cursor to the end of the other pin. The wire can be placed piece by piece at right
