    Route 455: CLK Net may have excessive skew

    While implementing designs such as counters I get warning such as Route 455: CLK Net may have excessive skew . I am not using any constraint file.

    Can that be reason? In that case can I ignore this??

    You may not be using a clock buffer, and that's causing the message. But why aren't you using a constraint? You may end up with a design that only runs at 60Hz.
