OwlVision GDSII Viewer

OwlVision is used to display GDSII (GDS, GDS2) Stream Format. It is implemented in Java programming language. Virtually, it can be run on all of the platforms. Please note that Java SDK or JRE is required before running the program.
For Unix/Linux users, Java may have already been installed on your computer. If your Java's version is from Sun Microsystems (not "gij"), you can start running the program by typing the commands described in the section "How to Run the Program" below. Otherwise, you still have to download and install Java JDK/JRE.

How to Download Java JDK/JRE

Java JDK/JRE can be downloaded from http://java.sun.com. Macintosh versions of JDK/JRE can be downloaded from http://developer.apple.com/java/.

About Downloading OwlVision

The downloaded file name should be "OwlVision-<version>.zip" or "OwlVision-<version>.tar.gz". Please decompress the file before running the program.

How to Run the Program

After you have had Java SDK or JRE installed on your computer, you can choose from one of the following options:

How to Increase Java Heap Size

    % java -jar -Xms512M -Xmx512M OwlVision.jar
    % java -jar -Xms1024M -Xmx1024M OwlVision.jar

Note / Known Problems
