signals with no driver

HI all, I have this problem. Every time when I start some simulatin on any scheme, Pr*tel show this message under any element or net: Signals With No Driver.
I use sinusuidal signal, connected to input (I simulate only analog schemes now).
In the message window this messages shows like Error classes
"Signal PinSignal_C6_2[0] has no driver", and under any element or net in Sch it shows some zigzag red line.

I use D X P 2004 with SP1
I don't know where is the problem. Anyone have this problem, or can help me ?
Thanks :)
 

signal has no driver

Check your sch, to see if there is some signal that is not connected.
This is a basic problem.
If sch is correct, then come back here for question.
 

signal namedsignal has no driver

This type of error is caused by not having the type of pin defined on your device. Every pin has to be "typed" as "input", "output", etc.

The error is trying to tell you that you have an input pin without a driving source. You probably meant to define the pin as "power", "output", or something else.
