Fatal Error: Segment Violation at 0x8 - Fatal Error: Segment Violation at 0x8 Description Due to a problem in the Intel® Quartus® Prime Pro Edition Software, you might see this error in the fitter stage. This error occurs when a virtual pin assignment is set to the pll_ref_clk pin of the High Bandwidth Memory (HBM2) Interface Intel® FPGA IP in an Intel® Stratix® 10 MX device. The pll_ref_clk pin must be connected to the dedicated pin and a virtual pin assignment cannot be used for this pin. Resolution To work around this problem, remove the virtual pin assignment from the pll_ref_clk pin of the HBM2 Interface Intel FPGA IP and connect it to a dedecated pll_ref_clk pin. This problem has been fixed starting with the Intel® Quartus® Prime Pro Edition Software version 19.3.
