In this tutorial, you will simulate your 4-1 mux.  QuickSim allows you to simulate the switching characteristics of your circuit.  You will also want to simulate your circuit using accusim to observe the behavior of your circuit more acturately.
 
 

Creating a QuickSim ViewPoint

• Well in typical Mentor fashion, there are multiple ways to create a QuickSim ViewPoint.  One way, the more time consuming way, is using the GUI interface.  If you would like to do it this way follow these instructions.
• The quicker way is to simply move into your ../tutorial/schematic directory.  Enter the line % adk_dve mux41  This will create a bunch of directories and design viewpoints including the ami05 file under your mux41 directory.

• To invoke QuickSim II move into your ../tutorial/schematic directory and enter % quicksim mux41/ami05
• Select the Open Sheet button.  A small window displaying your mux41 desing should appear.
• Select all the inputs and the output of your schematic.  Hit the Trace Button.  Here is what your screen should look like.
• Now download the following force file q_mux41.force  Save it in ../tutorials/f_files.
• Go to Setup -> Force -> From File and load the q_mux41.force file.
• Observe the output trace and convince yourself that your results are correct.

Now that we are convienced that our circuit logically behaves correct, we are ready to layout our circuit in the next tutorial.
