Cadence Setup Guide: ECE 410 (ver. Spring 2008 for use with PCs) Document Contents Introduction How to Setup Cadence for the First Time What to Do Each Time You Run Cadence Additional Resources Introduction This document provides step-by-step instructions for setting up your ECE 410 class directory to use the Cadence design tools. It also shows the steps you will have to complete each time you want to run Cadence after the initial setup. Cadence runs on the UNIX platform but we will be running it from PCs using a UNIX terminal program within Windows. How to Setup Cadence for the First Time Setup of Xming and PuTTy Xming software is a graphic server that runs on the PC to supply remote login to the Xwindow system. PuTTy software is used to setup a link between a remote Xwindow server (in UNIX or Linux) and the client PC. For programs that need a graphics interface, Xming will help display this interface at client side. Initial PuTTy setup 1. From a Windows PC, launch PuTTy at Start => All Programs =>PuTTY => PuTTY. 2. In the pop-up window, under Host Name key in a DECS server name. Use the server ‘mouse’ as shown below. Alternatively, you may use the ‘icfbprime’ server or switch to it if the server is slow. Under Connection type, select SSH. Cadence Setup Guide: ECE 410 13. In the Category list (on the left), select Connection => SSH => X11. In the panel that opens, check Enable X11 forwarding. 4. In the Category list, select Session to return to the first control panel. Under Saved Sessions key in key in a session name so you can save this configuration to be reloaded in the future. You can choose any name you’d like, such as ECE410. The example below uses the session name “mason_course”. Click Save. Your session name should now appear in the Saved Sessions list. Step 3 Step 4 Launch & Setup Xming 1. Launch the Xming server at Start => All Programs =>Xming => XLaunch. 2. In the window that pops up, select Multiple windows. Cadence Setup Guide: ECE 410 23. Click Next on each window pops up until the last window where you click on Finish to start the Xming server. Once Xming is running, an icon will appear in the tray at the bottom right corner of the screen. Launch & Setup Cadence • Return to PuTTy. Select the session name you saved and click on Load to reload the previously saved configuration. • Click Open at the bottom of the window to connect to a server. • In the pop-up terminal window, enter your engineering account ID and password to login to the selected UNIX server. • Once you login, you will be in a command prompt window where you can enter UNIX commands to complete tasks such as copy files, change directories, etc. Initially you will be in your home directory. To setup Cadence, you need to copy some files to your home directory and then create a working directory within your ECE410 class directory. • Copy the .cdsinit and .cdsenv setup files into your home directory by typing the following command lines at the terminal prompt: cp‗/egr/courses/personal/ece410/resources/.cdsinit‗~ cp‗/egr/courses/personal/ece410/resources/.cdsenv‗~ where the double low lines (‗) represent spaces. Do not forget the ‘dot’ before the filenames. These files will set up the Cadence simulation environment to use the spectre simulator and AMI06 transistor models by default. Copying these files to your home directory will apply these settings to all sessions of Cadence that run from your engineering account (including any other class that you might use Cadence for). If this will cause a problem for you, contact a TA for an alternative. • Change to your ECE 410 directory by typing the following in the command prompt cd‗/egr/courses/personal/ece410/<username> • Create a directory called cadence by typing mkdir‗cadence This will create a subdirectory where you should keep all of your Cadence files. You should always launch Cadence from within this directory. This will allow you to create different directories within your class directory, e.g., to save reports, without interfering with your Cadence CAD files. Cadence Setup Guide: ECE 410 3• Go to the directory cadence by typing cd‗cadence • Type source‗$SOFT/cadence (case sensitive) This command sets up your directory to work with Cadence, installing some necessary files (libraries) and linking to appropriate network files. • Type icfb& The ‘&’ is not required but will allow you to continue using the command prompt window while Cadence is running. You should always launch Cadence tools from your ‘cadence’ subdirectory. The icfb command will invoke the Cadence session. Two windows will open. The small window is known as the Command Interpreter Window (CIW) and will be present throughout your session. The other window is known as the Library Manager and it keeps track of all design files you create. In the Library Manager window you should see the following four libraries. If you do not, please consult a TA as soon as possible. NCSU_Analog_Parts, NCSU_Digital_Parts, cdsDefTechLib, basic Exiting Cadence This completes the initial setup for Cadence. If you plan to continue using Cadence (e.g., to do an assignment) skip this step. To exit Cadence, in the Command Interpreter Window (CIW) select File => Exit What to Do Each Time You Run Cadence After the initial setup, each time you run Cadence you need to first complete the following steps: • Launch Xming server at Start => All Programs =>Xming => Xming. • Launch Putty at Start => All Programs =>PuTTY => PuTTY. • Login to the UNIX system from Putty. • Change to your ECE 410 directory by typing the following in the command prompt cd /egr/courses/personal/ece410/<username>/cadence • Type source $SOFT/cadence (case sensitive) • Type icfb& to launch the Cadence tool. Additional Resources The class website has several helpful documents/links. See UNIX Tips for information on modifying your UNIX login to simplify running the Cadence software. See the Troubleshooting Guide for many answers to common problems. Detailed information for specific tools can be found in the linked Cadence Manuals. If you are not experienced with UNIX, the link to the DECS UNIX help page contains descriptions of basic UNIX commands. Cadence Setup Guide: ECE 410
