Gates are the standard simple logicgates, such as AND, OR, and NOT.
LOGICWORKS CIRCUIT SERIES
The devicesavailable to you are grouped into five classes or libraries: gates, generic, I/O, discretes, and 7400 series TTL as shown in the menu above. It should look something like the menu above. Make surethat the Circuit window is selected (it will appear highlighted as inthe screen image above). Let's start with a very simple circuit: an AND gate. We are now ready to enter gate schematics. The Circuits window is used for drawing schematics, and the lowerTiming window displays waveforms of instrumented "nodes" (that is,the labeled wires) within the schematic, similar to an oscilloscopetrace. LogicWorks is a tool for entering gate levelschematics of a digital system and performing simulations of itsbehavior.ĭouble-clicking on the LogicWorks icon results in the followingscreen: In this section, you will use LogicWorks to enter the schematicfor the half-adder. Draw thefull-adder in the space provided. Repeat Problem 1 for the full-adder circuit, which takes threeinputs and produces the two outputs SUM and CARRY. Fill in the truth table for thebehavior of the half-adder: X Y Sum Carry 0 0 0 1 1 0 1 1ĭraw a schematic for the half-adder in the space above. The half-adder is a function that takes two inputs, X and Y, andproduces two outputs, SUM and CARRY.
LOGICWORKS CIRCUIT INSTALL
Install logic works, type the following at the dos prompt: If there is no logic directory on the c drive then. Spelling andmechanics count! You may fill out the tables by hand.any drawingsmust be attached. Please type all of your (attached) written work. If you are familiar with the interface, pleasehelp out fellow students who might not be.įor each lab you will need to hand in the summary sheet (the lastpage of this and future assignments) and any hardcopy requested(indicated in the text by a bullet symbol). If you are unfamiliar with the Windows/Macintosh interface, find afellow student who is familiar with it and work with that person forthis first assignment.
LOGICWORKS CIRCUIT HOW TO
After completing thisassignment, you should understand how to draw circuit schematics andsimulate simple combinational circuits. This lab will introduce you to LogicWorks.
Introduction to Windows/Macintosh(TM) and LogicWorks Label yourattachments (Problem 1, Problem 2, etc., and put them in order). Use the same method above to label the port out part.Please fill out this lab and hand it in with the requiredprintouts attached. There will be one output line which will require the use of a "port out" part in Logic Works. Note that the text labels should become purple. Make sure you click the port in part and name them with their appropriate name such as S0, S1, A. Label each port in using the text tool (Ctrl - E). You will need a port in for each of the six inputs. This can be accomplished using a LogicWorks part called "port in." a. Use the created circuit from step 1 to create a part in Logic Works. The output should match the following table: si SO || OUTPUT 0 0 A 1 || 0 В 1 0 С 1 1 In other words, when S0 and S1 are both zero the MUX will select input A for use as the output. This MUX should have two selector lines SO and S1 and four input lines A-D. Please read for detailed information about MUX (Multiplexer). You can test out your circuit using binary switches and a Hex keyboard (use Ctrl-F to show signal values). Please read textbook page 140 section 3-7 Multiplexers before implementing this lab assignment (You can find the digital version of this section on the blackboard). This circuit will select one output from four inputs based on two addition switches.
Create a 4-1 MUX using ONLY tri-state buffers and inverters in Logic Works. Note that this lab assignment is individual assignment, which means each student needs to complete it independently. The purpose of this lab is to let you get familiar with the Logic Works software. It's the fastest solution to help you learn digital logic. Transcribed image text: Logic Works is an interactive circuit design tool that allows you to run quick and efficient simulations on screen.
