ADS is available underLinux systems at ECE/ENCS. This and other news about running ADS at Concordia is posted at http://www.ece.concordia.ca/~paknys/hpads.htmlThe HP EEsof web page http://eesof.tm.agilent.com/ has more information on ADS and other products.
Logging in and running ADS in the ENCS Lab: -------------------------------------------The computer lab H-921 is open 8am-11pm. To use it, read: hall.html (1) In the Linux terminal, type: module load ADS. (2) Type: ads
Documentation: --------- The F1 key or the Help icon leads to the documentation. A good place to start is Getting Started --> Introduce Me to ADS --> Simulation Also Take a look at: Components -> Analog/RF -> Intro to Circuit Components (ideal R, L, C,...) Components -> Analog/RF -> Distributed Components (microstrip, stripline, air inductors,...) Simulation -> Analog/RF -> Using Circuit Simulators Simulation -> Analog/RF -> S-Parameter Simulation For antenna pattern information, go to Simulation -> Electromagnetic -> Momentum -> Chapter 11 Radiation Patterns and Antenna Characteristics For information on printing, see http://www.ece.concordia.ca/ -> Documentation
Linecalc -------- Linecalc lets you figure out the transmission line dimensions for a given impedance, and vice-versa. It handles coax, microstrip, coupled lines, and many other types. It can be run from the Schematic Window -> Tools. It can also be run directly from the unix command line, by typing "linecalc."
s2p files --------- An s2p file is used to represent a two-port S-parameter table. It is used with Data Items ->S2P Comments have a ! For example, a file called gaasfet.s2p could contain: ! D. Pozar, "RF and Microwave Design," Example 6.3. # GHZ S MA R 50.0 !freq magS11 angS11 magS21 angS21 magS12 angS12 magS22 angS22 3.000 0.80 -89. 2.86 99. 0.03 56. 0.76 -41. 4.000 0.72 -116. 2.60 76. 0.03 57. 0.73 -54. 5.000 0.66 -142. 2.39 54. 0.03 62. 0.72 -68.

X-window screen dump -------------------- This can be convenient if you want to print a picture of the entire window. Use "xwd" and "xpr." xwd -nobdrs | xpr -device ps | lpr Some systems don't have xpr, so you can also use xview to view a *.xwd file. xwd -nobdrs > xx.xwd ; xv -rv xx.xwd
Design Kits, 2017 ----------------- Vendor components are no longer automatically installed. In the main ADS window, go to Design_Kits --> Manage Favorite Design Kits -->Add Library Definition File Go to "Computer" on the left, and go to /encs/pkg/ADS-2016.01/root/oalibs/vendor where you will find Analog_Parts_vendor_kit/ RF_Passive_SMT_vendor_kit/ HFDiode_vendor_kit/ RF_Transistors_vendor_kit/ Meas_SMT_Passive_vendor_kit/ S_Parameter_vendor_kit/ Microwave_Transistors_vendor_kit/ System_Lib_vendor_kit/ For example, if you want to have HFDiode_vendor_kit/ then navigate to it. In it, find the file called libs.def. Then press Open. Now, when you start making a project, the "New Workspace Wizard" will offer a list of libraries. Make sure to check off the ones that you will want. In the schematic window, there is an icon (books on a shelf, the library) where you will now find the components.
Problem Log ----------- 2006/08/02 Warning messages may occur when printing. If you have an old .XprinterDefaults try renaming it with mv .XprinterDefaults .XprinterDefaults-old and then let ADS create a new .XprinterDefaults the next time that you run it. 2004/05/07 If you're having trouble configuring the printer to print to a file, e.g. xprinter.eps, you might need to chmod 644 .XprinterDefaults
