Do some operations on a signal/variable in signal tap

Thank you very much for the replies. I see, yeah, I just wanted to have a quick way of filtering/manipulating the data and avoiding to utilise more hardware resources. Even though this is something different: I couldn't manage to display/list a signal twice resp. multiple times. I understand it kind of doesn't make sense, as it's already being displayed, but in my case it would very useful, as I wanted to group a big vector in multiple sub-words of x-bits, but I also wanted to do the same with n-bits.

Cheers,
