MAX V CPLD strange waveform

Hi everyone, 

I am using MAX V CPLD development kit for some simple logic and signal routing job. So I only use schematic editor.  

But the output waveform seems like riding on some pulse carrier. I attached a photo. Data5 is supposed to be identical with data8. Is there anyone knows why? 

Thank you

You need to provide you design files. 

 

With out thoses, there is no way for us to know why your circuit is not working.

Are they all clocked synchronously? They kinda look like runt pulses. If you can post the design file(s) we'll be able to give you a more definite answer.
