I'm looking to execute the pass through using HSMC Bitec DVI card. I put in my design the clocked video input connected to the clocked video output , but I didn't have any result.  

Please can someone help me in this problem.

I'm not sure which ref desgin you guys are talking about, but... 

 

I used the HSMC to Displayport card. 

I tried the output side, but it was working fine. 

I've tried on the A2GX and S4GX as well. 

and both working fine with me.

I am trying the same thing as you..The cyclone 3 example has a stupid mistake which I discovered today.It doesnot have the constraints file added from to it for CVI and CVO... 

The path to add them is: 

add the altera .v files. 

C:\altera\10.0sp1\ip\altera\clocked_video_input\src_hdl 

 

and also the sdc constraints file which is in the link  

 

C:\altera\10.0sp1\ip\altera\clocked_video_input 

 

Add for both CVI and CVO.. 

 

For more reference look the design  

 

http://www.bitec.ltd.uk/dvi_loopthrough_1080p_civ.pdf 

 

It is same deign but just with cyclone IV. 

Alteast the design synthesis successfully.U can add the files which are added in this design to the eg of cyclone 3 design and it works.. 

 

I prefer to create my own design, similar to the example but more logical.If it doesnot work I can upload it here in future. 

 

Hope it helps..

Hi, 

 

I got the code working on the DVI board Cyclone 3.The pre compiled code J8.sof can be successfully downloaded but when if I compile and synthesize the code on my own I have some errors but the precompiled code from bitec is working fine. 

 

If anyone needs help let me know!!
