Hello i am new in vhdl, but try it,
I want to make pipe between OV7670 and monitor, best thing is to use code of Hamsterwork's with Lauri's edition
http://hamsterworks.co.nz/mediawiki/index.php/Zedboard_OV7670 and
http://lauri.vősandi.com/hdl/zynq/zybo-ov7670-to-vga.html and want to adopt it to ML402 for Virtex-4 XC4VSX35, it requires 8 bit for each color in RGB,and bram address can be only 18bit wide, i made edition but cannot get any picture, link to this video on youtube
https://youtu.be/Tr-9UzEL-D8
code i modified, top_level, capture, vga, memory, clocking

http://download.files.namba.kg/files/147527022 pass :'123'

could someone help to check for video and code , what problem with which signal ?

Have you tried running this in a simulator? Did you create timing
constraints and use the timing analysis tool?

I do not know how to do it, I will route it and use oscilloscope

You need to learn how to design FPGAs properly. A simulator is not hard
to use. Most of the work is in writing a VHDL test bench to properly
exercise your design.

The timing analysis tool lets you specify the timing required in your
design such as clock cycle times, time from signal input to the clock
and from the clock to signal outputs. Trying to do this with an
oscilloscope is nearly impossible for any internal signals. The timing
analysis tool lets you do this as part of your design process without
loading the design onto your board.

If you haven't tested the design before routing then there
is no reason to believe your circuit does what you would
like it to do.

If you haven't tested the design after place and route then
there is no reason to believe you specified your system
requirements correctly, nor that the tool satisfied the
unstated requirements (naturally!), nor even that it was
able to satisfy the stated requirements.

You have already been given helpful advice. Simulate, get it working in
simulation.

It's your choice to use or ignore that advice, that's not our problem.

Others have explained that you will debug the logic of your design much
more easily in a simulation than on the bench. Debugging in the chip is
hard because you need to bring signals out to see what his happening.
The simulator allows you to view any signal at any time. You can get
waveform displays, or probe signals in a list showing the current value.
You can even walk through the code with breakpoints if that is how you
like to do it (I never use this but others do).

Then, once you have the logic working correctly you can deal with timing
issues. To use the timing analysis you need to create timing
constraints. These constraints consist of clock period (or frequency),
input clock setup times and output delay times. If you don't understand
what these timing constraints mean then you need to ask questions. Just
posting part of a timing report and saying "help" isn't the way to get
useful help.

Here is a pointer. In your previous post the tool gives you one very
important error message....

INFO:Timing:2698 - No timing constraints found, doing default enumeration.
