You can find additional help at the Digital Works Home Page address above. Other sources of help would be your TAs, each other, and me. Getting Started 3. The symbols on the toolbar are exactly the same as the logic symbols you have in class. You'lllearn about all those other gates and symbols soon. These are also available in the DW toolbar, they are the little circles on the right. If you can't identify one of the symbols, just hold the cursor over it for a second and a tag will pop up telling you what the part is.
To place a part in your circuit, click once on the part you want in the toolbar, then double-click at the point you want the part to be placed. If you want to place multiple copies of the same part, you only need to select it from the toolbar once. Then simply point at the part you wish to move, then press and hold the left button. Drag the part to its new location, then release the mouse button. This is your wiring tool why a pencil, I don't know. To connect components in your circuit together, first click on the wiring tool.
Go to the first element you want to connect. Click the left button once to start drawing. Move to the second point you wish to connect while your drawing the wire, your cursor will turn into a pencil. If you wish to end a wire without connecting to another circuit element, press the right mouse button rather than the left and the circuit will terminate in a small square indicating an external connection - useful for drawing chip schematics.
Wires may start either at connection points on circuit components or at any point along another wire. It generally looks better if all your wires run vertical or horizontal, never at crazy angles see figure Figure 1: Good and bad wiring practices3. This capability is provided in Digital Works in the form of macros. Creating macros will be discussed later. A file dialog box will pop up asking you to find the macro file. Once you have selected the macro file, an outline of it will appear in your schematic.
Click once more to make the placement of your macro permanent 3. Sequential simulations will be discussed in section 4. For the first 6 or 7 labs, you will be doing strictly combinational circuits, meaning that for all intents and purposes in the simulator everything happens at once.
