1.2. Changes to Software Behavior

This section documents instances in which the behavior and default settings of the Intel® Quartus® Prime Pro Edition software have been changed from earlier releases of the Intel® Quartus® Prime Pro Edition software.
  • Starting with the Intel® Agilex™ device family, the EDA netlist writer does not support IBIS model generation. The EDA netlist writer continues to support IBIS model generation for earlier device families.

    You can download IBIS models for all device families from the following web page: IBIS Models for Intel® Devices. This page is updated as IBIS models for devices become available.

Refer to the Intel® Quartus® Prime Default Settings File (.qdf), <Quartus Prime installation directory>/quartus/bin/assignment_defaults.qdf, for a list of all the default assignment settings for the latest version of the Intel® Quartus® Prime software.
