    ADS Fundamentals - 2002  LAB 1: Circuit Simulation Fundamentals  Overview - This lab covers user interface basics, ADS files, schematic capture,simulation, and data display. In addition, tuning and ADS example files are alsocovered. OBJECTIVES ã Create a new project and schematic designs ã Setup and perform S-parameter simulation ã Display simulation data and save files ã Tune circuit parameters during simulation ã Use the Examples files and node names ã Perform a Harmonic Balance simulation ã Write an equation in the data display  Lab 1: Circuit Simulation Fundamentals 1-2   Table of Contents  1.

Add a wire label (node name) , simulate, plot data ...................................................16  Lab 1: Circuit Simulation Fundamentals  1-3 PROCEDURE 1. Start ADS on the computer. Typically, on a PC, you can use the Start button to run ADS or a shortcuticon on your desktop. For UNIX users, type the script/ command at thetherminal prompt (hpads or similar).Main window: PC version (UNIX is similar)  Lab 1: Circuit Simulation Fundamentals 1-4 2. Create a new Project. For this step you will use the icons on the Main window. Using icons to executecommands usually requires fewer mouse clicks. You can identify what an icon does byplacing the cursor on the icon to display a text box: this is called balloon help  .a. In the Main window, click the icon: View Startup Directory. This willshow that you are in the default starting directory for ADS projects.b. Click: File > New Project . When the dialog box appears, you will seethe default working directory. On your own computer it will beC:\users\default but in an ADS classroom it may be different(C:\users\ads) so check with the instructor.c. Insert the cursor at the end of the line and type the name lab1 as shownhere Note on Length Unit - The length unit is a setting for components such asmicrostrip lines and is also used for layout. For this lab use the defaultvalue (mil).d. Click OK and the project is created and a schemaitc window opens.Create a NewProjectView Startup Directory
