DE2-70 - DE2_70TV demonstrator is not working

Hello, I have a Terasic DE2-70 board and I am trying to run the demonstrator DE2_70TV. 

 

The .sof file that comes with the CD and the demonstrator downloaded internet is working perfectly, but if i recompile these projects and I put them again in the FPGA the image i get is noisy and with some vertical lines. :eek: 

 

My version of Quartus II 11.1 Web edition build 173.  

 

I would appreciate your help to solve this problem. 

 

Thank you! :D

i tried with Quartus 9.1 and with Quartus 10 both versions of the demonstrator. they work ok if you compile it with the corresponding version. 

 

But if i want to use the video decoding for another project, the same vertical lines appear. Do you know why? 

 

Thanks!

you have to add the time constraints that come with the original program

Can you explain a little more about time constraints? 

 

And can you also explain how you have add the time constraints on the DE2-70TV I cant find the orginal time constraints.

there are in a file DE2_70_TV.sdc 

you can add from settings, assignments 

• In Timing Analysis Settings, select Use TimeQuest Timing Analyzer during compilation.  

• In TimeQuest Timing Analyzer add the time constrains file.  

 

if then check the report of timing after compiling  

 

also if you have problem read a tutorial about TimeQuest, it is short :)

I dont have the DE2_70_TV.sdc file in the Demonstrations/DE2-70_TV map 

Must I create it first or is this a fault on the cd.
