ASITIC is a CAD tool that aids RF/microwave engineers to analyze, model, and optimize passive metal structures residing on a lossy conductive substrate. This includes inductors, transformers, capacitors, transmission lines, interconnect, and substrate coupling analysis.
ASITIC runs in the X Window environment under most UNIX platforms. A Win32 version will be released in the near future. To run ASITIC download ASITIC first and set up a technology file describing your process. ASITIC is fairly general, allowing any number of substrate layers or metal layers to reside in the technology. Typical IC processes utilize 3 to 4 layers of substrate and oxide and 3 to 6 metal layers. Once the technology file is set up, execute
asiticfrom the command line. Make sure that your DISPLAY environment variable exists and points to the correct screen name. This can be done by typing
setenv DISPLAY $hostname:0.0where
$hostnameis the hostname of the machine where you would like to display the graphics.
Next you will be asked to enter the name of the technology file and you will be presented with an ASITIC prompt. You should also see a blank graphics window. You are now in the ASITIC environment and you can type commands directly into the ASITIC "shell". For a list of commands, see below. For a quick overview on how to get started, read the Quick Start Guide
