How to make a Subcircuit in LogicWorks

1. Create your full adder as you did in Lab #0. (Do not put any binary switches on the inputs, or binary probes on the outputs.)
2. Put an input port on each input: you'll find the 'Port In' device in the connect.clf library.
3. Put an output port on each output: you'll find the 'Port Out' device in the connect.clf library. (You may want to rotate the output port 180 degrees: use the leftmost icon in the Palette to do this.)
4. Give names to the input and output ports, as in A, B, and Cin for the input ports, and S and Cout for the output ports.
5. Save this device, but leave its window open.
6. From Tools menu select DevEditor. From the Options/Subcircuits/Part type menu choose the "Create a subcircuit symbol and store the subcircuit with it.." option..
7. From the menu of parts that is displayed in the 'Select Internal Circuit' window, select the device you just made, and click 'internal'.
8. Click 'Done' to close the PartType dialog box. You'll notice there is a list of port names in the window at the left of the DevEditor window.
9. Choose the AutoCreate Symbol option in the Options menu.
10. Type the same names (e.g. A, B, Cin) that you used above in the 'Left Pin Names' window in the AutoSym window; separate them with a Return.
11. Type the same names (e.g. S, Cout) that youused above in the 'Right Pin Names' in the AutoSym window; separate them with a Return.
12. Type the name you want for this circuit (e.g. myFullAdder) in the Part Name window, and click on 'Generate'.
13. Choose File/Save Part As option to save this circuit in one of the libraries, (e.g. 'primlogi.clf').
14. Now you can add this subcircuit just like any other part in the libraries.
