Hi Zhongyao, I am not sure about the downstream implementation of other vendors, but currently in the tune parameters of our design, we are modeling that with our `common_vector_cost` instance with int_stmt_cost and fp_stmt_cost greater than 1. I guess that can already suffice for many cases? Also, we can have designs whose FP vector unit number is different than the integer vector unit number, and we may still need to bother with the `common_vector_cost` struct.
