Error(332000): can't read "pll_instance_name": no such variable - Error(332000): can't read "pll_instance_name": no such variable Description Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 17.1 and earlier, you may see this error message when compiling a design that includes the LVDS IP. This problem occurs when the IP is in external PLL mode and targets an Intel Stratix® 10 device. Resolution To work around this problem, comment out the following line from the LVDS IP SDC file set_max_delay_in_fit_or_false_path_in_sta_through_no_warn ${pll_instance_name}|lock $max_delay This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software.
