Description
This warning message occurs when a GLOBAL primitive is instantiated in a design targeted for Stratix™, APEX II, APEX™ 20KE, and APEX 20KC devices.
This warning is to tell you that the LeonardoSpectrum synthesis has not mapped the GLOBAL to a WYSIWYG atom. However, a global component is created and the Quartus® II software will make a global assignment if dedicated global clock lines are available.
