Default Simulation Tool with Video Display

Does any development IDE have a video output tool?

The simulation tool should allow large amounts of video
data to be seen in one view. The data could be in
different formats with different line/blanking signals.
YCrCb color format would also be advantageous.
For me right now color isn't an issue.

Simple use would be to click on Video_In and
you would see a screen with your video input file,
and then write something like this, for example,
if Video_In > Threshold then
Video_Out <= 200;
else
Video_Out <= 40;
end if;
and then if you click on Video_Out, you would see
your thresholded video image, or any other video
processing you might be working on. Verilog would
be OK too.

Not directly, but you can write some behavioural code in your test
bench to capture the video and write it into a memory. Use the
scripting facility of your simulator to read the contents of the
memory and write it to a bitmap in a popup window. I know Modelsim
can do this; I've seen it. (Note: this only works in the (expensive)
versions of Modelsim that support Tk.)

Regards,
Allan.
