Why isn't my synchronous RAM inferred?

Environment

  • Intel® Quartus® Prime Pro Edition
  • On-Chip Memory (RAM or ROM) Intel® FPGA IP
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    In the Quartus® Prime software, inferred RAMs must have a registered read path.

    However RAM will not be inferred if the read path register is:

    • subject to a preserve attribute.
    • implemented as an input or output register in an IO cell.
