openFPGA 1.1 beta 5 Changelog

Customized Controls

Existing openFPGA cores are now fully remappable on a per-core basis via the OS. Users can remap specific controls, reset to defaults, or remap-all with an easy and familiar guided process. Developers do not need to update cores as long as input.json has been included in the current release.

Enhanced Core Organization

Now users can optionally organize their growing list of openFPGA cores using categories. When the new “Group openFPGA” setting is enabled (Settings > Analogue OS), the openFPGA root menu will alphabetically group and sort cores by the category key defined in <platform>.json. Platforms with no defined category will be added to the “Uncategorized” list.
