Boise State University Digital Systems Laboratory by S M Loo Arlen Planting Department of Electrical and Computer Engineering Boise State University First Released Spring 2005 with ISE 6 3i Updated Fall 2006 with ISE 8 1i EE230L Introduction to Xilinx ISE 1 Boise State University Digital Systems Laboratory Introduction This tutorial will introduce the Xilinx ISE Computer Aided Design CAD Software It will acquaint you with the BSU Xilinx TTL symbols created from ISE native symbols used when constructing digital circuits on a proto board The goal of this tutorial is to provide you with the skills to use ISE to facilitate learning digital designs This software tool is capable of simulating any digital design that you will attempt in this class and more importantly in a real world environment You will enter a logic circuit that implements the equal function This tutorial has been prepared by your friendly neighborhood lab assistant and course instructor EE230L Introduction to Xilinx ISE 2 Boise State University Digital Systems Laboratory Start Project Navigator Find the Xilinx ISE 8 1i icon on desktop to start Xilinx Project Navigator and double click the icon This is the Xilinx ISE window ISE always opens the most recent project If this subwindow contains data then use FILE Close Project Note Project Navigator in Windows task bar EE230L Introduction to Xilinx ISE 3 Boise State University Digital Systems Laboratory Create New Project To create a new project File New Project EE230L Introduction to Xilinx ISE 4 Boise State University Digital Systems Laboratory Name Schematic When all the fields have been filled click Next EE230L Introduction to Xilinx ISE Give a name to the project Make sure that the project location is where you want it It is okay to place your folder on the M drive however D drive is preferable This tutorial has been written on a computer without a D drive The lab computer has a D drive and has been set up to clear all user s data when rebooted Top Level Module Type is Schematic 5 Boise State University Digital Systems Laboratory Target Device Specification This is important and will be used later for FPGA designs Make sure other values match what is shown This device specification is required for targeting the FPGA prototyping we have in the lab This will be important when we download to the FPGA EE230L Introduction to Xilinx ISE 6 Boise State University Digital Systems Laboratory EE230L Skip these Dialogs Introduction to Xilinx ISE 7 Boise State University Digital Systems Laboratory Lab1 Equals Project Note the project name and target FPGA ID EE230L Introduction to Xilinx ISE 8 Boise State University Digital Systems Laboratory Add Schematic Source to Project Now we need to add a schematic source to the project EE230L Introduction to Xilinx ISE 9 Boise State University Digital Systems Laboratory Name Schematic Select Schematic Name Schematic EE230L Introduction to Xilinx ISE 10 Boise State University Digital Systems Laboratory New Schematic Window A blank schematic sheet has been created and added to the project Double click on You will get this schematic capture window Re size the window to optimize the working area Try to close the middle window the Select Options window EE230L Introduction to Xilinx ISE 11 Boise State University Digital Systems Laboratory Change Page Size Since this is a small design we will change the page size to fit an 11 x8 5 sheet of paper EE230L Introduction to Xilinx ISE 12 Boise State University Digital Systems Laboratory Set Page Size to 11 x8 5 You can always increase the page size by revisiting these steps EE230L Introduction to Xilinx ISE 13 Boise State University Digital Systems Laboratory Add Symbols Now we want to add the component symbols to the schematic Select the Add Symbol button from the toolbar Hitting the Esc key will cancel the Add Symbol mode EE230L Introduction to Xilinx ISE 14 Boise State University Digital Systems Laboratory Add Title to Schematic Diagram Symbol categories Symbols within each category EE230L Introduction to Xilinx ISE 15 Boise State University Digital Systems Laboratory Add Inv Symbols Select Logic Category and find Inv abbreviation for inverter Place two Inv on the sheet by clicking at the desired locations on the sheet Symbols can be moved by clicking once at the symbol This turns the symbol to red then it can be moved EE230L Introduction to Xilinx ISE 16 Boise State University Digital Systems Laboratory Add 2 input AND Symbols Select the AND2 symbol and click on drawing where you wish to add symbol Add two AND2 symbols EE230L Introduction to Xilinx ISE 17 Boise State University Digital Systems Laboratory Add 2 input OR Symbol Select the OR2 symbol and click on drawing where you wish to add symbol Add one OR2 symbol Organize the symbols as you see in this figure EE230L Introduction to Xilinx ISE 18 Boise State University Digital Systems Laboratory Label Symbols Right Click on symbol and select Object Properties This step is to label the symbols to something that could be more meaningful to you by changing to the Value of InstName This step is optional EE230L Introduction to Xilinx ISE 19 Boise State University Digital Systems Laboratory Set Symbol s Properties Change InstName Value as you desire EE230L Introduction to Xilinx ISE 20 Boise State University Digital Systems Laboratory Add Wires EE230L Now add wires to connect the symbols Close the Source window by pulldown menu View Source Open the Processes window by pull down menu View Processes Select the Add Wire button from the toolbar On the options tab select the Use the Manual method Hitting the Esc key will cancel the Add Wire mode and lead to this window that is very useful for selecting a wire Introduction to Xilinx ISE 21 Boise State University Digital Systems Laboratory Add Wire Step 1 Connect these two segments as indicated by the green arrows EE230L Introduction to Xilinx ISE 22 Boise State University Digital Systems Laboratory Add Wire Step 2 Hover over as indicated by the red arrow until the cursor image changes to connection point indicator Connection point indicator EE230L Introduction to Xilinx ISE 23 Boise State University Digital Systems Laboratory Add Wire Step 3 Left click hold the left button and drag wire as shown in figure Once connection indicator appears release mouse button EE230L Introduction to Xilinx ISE 24 Boise State University Digital Systems Laboratory Schematic with Wires Repeat until you have connected all of the
