Warning(13469): Verilog HDL assignment warning at mbl_table_mux.sv(116): truncated value with size 24 to match size of target (23)

Description

This warning might be seen in the Intel® Quartus® Prime Pro Edition Software version 23.3 when you compile a design containing the Memory Subsystem Intel® FPGA IP that instantiates a Content-Addressable Memory Intel® FPGA IP using the MBL algorithm. It happens when a Content-Addressable Memory Intel® FPGA IP instance using MBL is connected to an external memory that is not large enough to hold both hash and key/result tables.

Resolution

This warning cannot be ignored.
To work around this problem in the Intel® Quartus® Prime Pro Edition Software version 23.3, perform one of the following solutions:

• Lower the log2 number of the key/result table
• Increase the size of your memory device
• Reduce key/result width
• Lower the number of bins per row

This problem is scheduled to be fixed in a future release of the Intel® Quartus® Prime Pro Edition Software.
