This is the other window where important things happen.1 LogicWorks 4 Tutorials Jianjian Song Department of Electrical and Computer Engineering Rose-Hulman Institute of Technology March 23 Table of Contents LogicWorks 4 Installation and update Tutorial #: Introduction to LogicWorks Objectives Starting LogicWorks 4 on your laptop Obtaining and placing gates in schematic window Connecting gates Labeling inputs and output signals and pins Connecting binary switches to input pins Connecting binary probes to outputs of the circuit Verifying logic function of the circuit with binary switches and probes Connecting clock devices to input pins and changing clock period Displaying and Changing gate delay time Setting trigger Verifying logic function of the circuit with clocks Verifying logic function of the circuit with device delay Copying schematic and waveform to PowerPoint or Word Creating signals with no waveform in a timing diagram Tutorial #2: Device symbols and sub-circuits Objectives Example sub-circuit: 74LS8 4 2-input AND gates Draw the schematic of the following turn-signal circuit without clocks Create Port Connectors Create a device symbol for the turn-signal circuit Create a new library, my_library and save the symbol in it Save your turn-signal sub-circuit to another file Construct a turn-signal test circuit with the device symbol Create a sub-circuit and device symbol with Top-Down approach Edit a device from a library Tutorial #3: A 4-Bit Counter Device with Bus Pins Objectives: to create a sub-circuit and device symbol with bus pins Create bus port connectors Create a 4-bit counter sub-circuit with bus port connectors Create a 4-bit counter device symbol with bus pins Create a 4-bit counter with the counter symbol Different pin names in a top-level circuit and Bus Pin Information Debugging techniques Modifying a bus port in a subcircuit Tutorial #4: Making a ROM device with a hex file Objective: to create a ROM device that is initialized by reading a text file Create a plain text file Create a Rom that is initialized from a file.4 Jianjian Song LogicWorks 4 Tutorials (5/5/3) Page of 4ΔΆ LogicWorks 4 Installation and update Install LogicWorks 4 from the CD from the book LogicWorks 4 Interactive Circuit Design Software. 1.3 Timing Window When active, the Timing Window will display the waveforms associated with your circuit. 1.2 Parts Palette The Parts Palette, or the Library, contains all of the parts that you will use to design circuits, and some parts that you will not use. Circuits in the Drawing Window act in concert with timing information in the Timing Window, as will be seen later. TOOLS Drawing Window Drawing Toolbar Simulation Toolbar Parts Palette Timing Window 1.1 Drawing Window The Drawing Window, also called the Design Window, will contain the circuits you design, and is your main interface with the software. "Double-click" and "click-and-hold" should be performed as indicated. Note: Unless mentioned, all mouse-click are left clicks. It is recommended that you go through this tutorial while you are seating in front of the computer for practice. Since the design and simulation steps are meant to verify the correct operation of a circuit before it is implemented, and as a result, save valuable time. INTRODUCTION Logic Works provides the student with a great deal of flexibility in the design and simulation of the digital circuits that he or she will implement using the chip set and trainer kit.
