Some issues about functional simulation

Hi,all when i do the functional simulation for my projection,i find that some of the initial values of my signals are not cleared to "0".how can i do to clear them? thanks.

What makes you think that the integer signals should be initialized to 0 without an explicite initialization? Actually Quartus initializes them apparently to their lower bound. As said, you can use an explicite initialization. I wasn't aware of this particular behaviour with integers that have a negative range, but I'm generally using explicite initialization whenever the initial state of a signal matters.
