Why does the Quartus® Prime Pro Software allow multiple F-Tile Reference and System PLL Clocks IP to be instantiated per F-Tile in my design?
Description
Due to a problem in the Quartus® Prime Pro Edition Software Version 24.3 and earlier, multiple F-Tile Reference and System PLL Clocks IP are incorrectly allowed to be instantiated per F-Tile.
Creating multiple instances of this IP in your F-Tile design will cause the System PLL reference clock, FGT reference clock monitor, and protection circuitry to be non-functional.
Resolution
To work around this problem in the Quartus® Prime Pro Edition Software Version 24.3 and earlier, ensure that only one instance of the F-Tile Reference and System PLL Clocks IP is instantiated per F-Tile.
This problem has been fixed starting in version 24.3.1 of the Quartus® Prime Pro Edition Software.
