This can be done witha switch or by naming the set and clear wires with the special name "1". To print out thetiming diagram ensure that the timing window is selected and choose PrintTiming from the File menu.Ĩ.1.8.COMMON DEVICES 8.1.8.1.D AND JK FLIP-FLOPSīoth flip-flops have a set and reset input which is active low.They must behooked up to a one for the flip-flop to behave normally. The order of the signalscan be changed by selecting the name and moving it up or down. In this waythe behavior of a circuit can be monitored over time. Miscellaneoustext can be placed at any point on the circuit as well.Ĩ.1.7.TIMING WINDOW USEThe timing window is like an oscilloscope in that it displays the value of anamed signal on the vertical axis and time on the horizontal axis. The label can be moved at a later time just like any other device.ĭevices can also be named. Aslong as you hold down the mouse button the position of the I-beam can be moved.To type in the label release the mouse button and enter the text followed byreturn. The pencil will switch to an insertion point I-beam. Click the pencil near thewire you want to label(Don't click nearer than 5 pixels to a device or thenaming won't work). To name a device or wire select Name fromthe Edit menu. The organization of your circuit is greatly improved by labeling switches,gates, etc. The selected device will now follow the mouse pointer althoughthe program will limit the movement based on the current circuit. To move a device place the pointer inside the device and press and hold themouse button. To switch back to the pointer clickanywhere in the menu bar. Move the tip of the bolt to whatever device or wire isto be deleted and click the mouse button. The pointer will change toa small lightning bolt. To delete something select Zap from the Edit menu. Click on the starting point and ending point of a desired wire and thewire is automatically drawn. The cross icon inthe lower corner of the circuit window provides a different way of placingwires. Intersections willbe marked with a small square simulating a solder connection. Note that only horizontal or vertical wires can be drawn.If your wire crosses another wire there will be no connection made unless youstop at the point where you would like a connection made. As long as the button is held down a wire willfollow the pointer. To draw a wire press and hold the mouse button with the pointer near anotherwire or chip input or output. To return to thepointer click anywhere on the menu bar or click on the pointer icon in thelower corner in the window. Move the symbol to the desired location and click the mouse toplace the device there. An alternateway of specifying the orientation is by pressing the appropriate arrow key onthe keyboard. The orientation can be changed by clicking on theorientation icon in the lower left corner of the circuit window. The pointer will be replaced by the flickering circuit symbol of thedevice you selected. All thesefunctions can be accessed from the menus as well.įrom the device menu select the device you would like to place in the circuitarea. The following circuit window illustrates the short cuticons that are located in the bottom left hand corner of the window. The circuit window is the window that is used mostfrequently so resize it to fill the screen by clicking on the zoom button inthe top right corner.
