± A.H.Dixon Laboratory Exercise 1 1 BUILDING CIRCUIT DIAGRAMS 1. Launch DesignWorks 4.0 (or LogicWorks). 2. The screen display includes a menu bar, two tool bars, a timing window (at the bottom) and a parts palette (on the right). 3. On top of the main window should be a window titled ”Welcome to Design- Works”. Within this box, under the heading ”Create a New Design from a Template,” select from the list box titled ”Generic Simulation” and then click on the button ”Create” which appears when the selection is made. (Note: In LogicWorks 5 this window simply provides you with the ”Create” button to click.) 4. The ”Welcome. ..” window should disappear and a large window should be displayed that contains a grid. It is within this ”main” window that you will place your digital design. 5. Select the View pulldown menu, and then click on each of the options to determine where each of the tool bars, display bar, timing window, and parts palette are located. 6. At the top of the parts palette window, the phrase ”ALL LIBRARIES” should be displayed. Change this to read ”Simulation Gates.clf”. A list of gate level components will appear in the display underneath. 7. This tutorial will construct a circuit that implements the boolean functions: s = ( x y ) z c = xy + z ( x y ) From the expressions, we will require XOR gates, AND gates and OR gates. In particular, we will use only 2-input gates. Scroll down the parts palette window until the XOR-2 component is located. Note that components are listed in alphabetical order. The number following the gate name indicates the number of inputs. 8. Double-Click on the XOR-2 component name and move your cursor onto the design screen (the one with the grid displayed). You will notice that your cursor changes to the graphical representation of a 2 input XOR gate. Position this image somewhere near centre and top of the design screen, and
