Range must be bounded by constant expressions


Recommended Posts

I am trying to implement the following in systemverilog.



for(int i=0;i<=124;i=i+6)


offset = DFF_data[ ((2*i)+1) : (2*i) ]; // Error !

data_output[i+offset]= data_input;



I get the following error in the line marked above: Range must be bounded by constant expressions. The error ocuurs beacuse of the use of "i" in defining the range of array DFF_data. But writing this without "i" seems impractical. I am using QuestaSim 10.1d. Has anyone come across such a situation?
