Honored ContributorThe use of the '|' operator in this case is referred to as a reduction operator. val will get the bitwise OR of all the bits in stimulus. So basically if any bit in stimulus is set, val will be a '1', otherwise, it will be '0';
It's the same as writing val <= stimulus[11] | stimulus[10] | stimulus[9] ..... | stimulus[1] | stimulus[0]; only obviously signicantly shorter. Jake
