How to change a library refence in modelsim?

Hello Tricky,

My point is maybe not clear:

It is not my code but the altera ip code for ALT_LOG that instantiates altsquare.

I only instantiate ALT_LOG.

I know you can help me sort this out, my post above explains in detail what te problem is. I think i need to do what is the case below, but i do not know how.
