Column sum constraint for an 2D array

[dave_59]

Constraint sum overflow

module abc; class a; rand int unsigned aa; rand int unsigned bb; constraint c2 { aa + bb <= 10; } endclass initial begin a a1 = new(); a1.randomize(); $display(a1.aa, a1.bb); end endmodule if I use the ‘int’ datatype, the sum is overflowing and the aa & bb are assigned with bigger values. Is there any solution to constraint aa & bb lessthan 10?
