Constraint array

Constraints to generate random password in SV

In reply to Liiiiiz: The result of the expression item inside {[97:122]} is true 1’b1 or false 1’b0, both 1-bit. The sum() of those expressions will also be a 1-bit result. You just need to cast that expression to a large enough width so the sum of 10 possible 1’b1 values does not overflow. Cast to 4-bits or int would work as well. I think Alokpati used 7 because that was the element size of pw array, but that size is no longer relevant. Only 10 numbers can be chosen because that is the size…
