Technical Note for
Windows Users
The Windows operating system requires that applications check-in every five
seconds, or the application is deemed non-responsive. Non-responsive
applications are given a figurative kick-in-the-pants, and asked to repaint the
screen. When the screen paint itself is taking more than five seconds, an
application can be forced into an effective infinite-loop of paint requests from the
operating system. If a Windows user ever notices ACE being called
non-responsive by Windows (check the application title bar), the application has
most likely entered this looped painting state. To escape, change back to the
Project perspective (or any other perspective without the Floorplanner view
visible), then on this preference page, ensure that incremental rendering and
tiled rendering are both enabled for the current design’s complexity level. If both
are already enabled, please call Achronix Technical Support for guidance on
further Floorplanner optimization tweaks.
