Why does the Quartus® Prime Pro compilation fail during the Analysis & Synthesis stage when No Development Kit is selected in the F-tile SDI II IP Design Example with AXIS-VVP Full enabled?

Environment

    Intel® Quartus® Prime Pro Edition
    Interfaces
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

Due to a problem in the Quartus® Prime Pro Edition Software version 22.2, the following error message appears during Quartus® Prime Pro compilation when generating the F-tile SDI II IP example design with AXIS-VVP Full enabled and No Development Kit is selected:

  • Error(20521): The input refclk of IOPLL axi4s_clk_iopll_inst|axi4s_clk_iopll|tennm_pll is driven by an illegal source: a virtual pin. An IOPLL refclk's source must be either another IOPLL or a dedicated refclk input pin
Resolution

To work around this problem, when selecting No Development Kit in F-tile SDI II IP Design Example with AXIS-VVP Full enabled, comment line <set_instance_assignment -name VIRTUAL_PIN ON -to clk_3a_gpio_p_2> in the Quartus® Settings File (QSF) file settings and recompile the design.

This problem is fixed beginning with version 25.1 of the Quartus® Prime Pro Edition Software.
