Dear Gurus,

Is it possible to make an assignment like this?

group these six LVDS signals and put them on the same bank

PS: I do not want to select the bank myself. I want the tool to find the same bank for them.

    I don't think that's possible, other than generating a random number in the script and use this one as the bank. Is there any reason why you can't pick a bank number yourself?
