Why am I getting straight blue or red lines in my wave?

I did not get any error in simulation. But, I am getting blue and red lines in waveforms. What am I doing wrong?

It seems as though none of the inputs - clock ,start, clear are being driven in the design simulation. Have you forced any value to the inputs? If you have written a test bench , make sure you have driven all the inputs to known values. Failure to do so may lead to unwanted values / X in the outputs.
