Error (10232): Verilog HDL error at altera_merlin_burst_uncompressor.sv(174): index 5 cannot fall outside the declared range [4:0] for vector "addr_width_burstwrap"


Due to a problem in the Quartus® II software version 11.1 and later, you may see an error similar to the above message when compiling a design containing a Qsys system. The root cause of the problem is related to master address width limitation under the following conditions:

address width <= burst count width + log2(number of symbols/burst)


To work around this problem, perform one of the following two actions:

  • Assign the slave to a higher base address which will force the master\'s address width to increase
  • Modify the slave to have a larger address width

This problem is scheduled to be fixed in a future release of the Quartus II software.
