  • Starting with Intel® Quartus® Prime Version 18.0, the features and devices supported by the Intel® HLS Compiler depend on what edition of Intel® Quartus® Prime you have. Intel® HLS Compiler publications now use icons to indicate content and features that apply only to a specific edition as follows:
    Indicates that a feature or content applies only to the Intel® HLS Compiler provided with Intel® Quartus® Prime Pro Edition.
    Indicates that a feature or content applies only to the Intel® HLS Compiler provided with Intel® Quartus® Prime Standard Edition.
  • Added important prerequisite for Intel® MAX® 10 users to Synthesize your Component IP with Intel® Quartus® Prime Standard Edition .
  • Revised Debugging during Verification to clarify how to view the waveform in ModelSim* after simulation.
