Description
Due to a problem in the Quartus® Prime Pro Edition Software version 24.1, the LPDDR4 EMIF IP may hang when attempting to read from memory using the AXI-4 interface due to signals being unintentionally optimized away.
Resolution
To workaround this problem, add the /*synthesis dont_merge syn_preserve = 1*/ attribute to all the registers of the AXI bus driving the Trafic Generator.
