Due to a problem in the Quartus® Prime software version 16.1.2 and earlier, you may see the font names distorted or rendered in the Qsys System Integration Tools. This problem occurs on Windows PCs when high DPI display has been selected
To work around this problem for Windows, go to
Control Panel -> System -> Advanced system settings -> Environment Variables -> System variables, set the
Variable -> _JAVA_OPTIONS
Value -> -Djava.net.preferIPv4Stack=true -Dswing.systemlaf=javax.swing.plaf.metal.MetalLookAndFeel
If you were using Linux, type the following command
set _JAVA_OPTIONS=%_JAVA_OPTIONS% -Dswing.systemlaf=javax.swing.plaf.metal.MetalLookAndFeel
This problem is scheduled to be fixed in a future release of the Quartus Prime software.
