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.)

Allan.

LabView tools to process and display video?
I'm starting a project that will digitize a non-standard video signal from a microscope using a 6115 DAQ board, and I want to display it at the full frame rate of 1&nbsp; frame per second at 1024x1024. Some experimentation shows that just dumping the data into a standard Picture structure won't even get close the the 1 second frame rate.What toolset will I need to get hardware-accellerated video display?&nbsp; Will IMAQ Vision do the job?&nbsp; Which VIs?I've thought about using the "textures" in 3-D picture controls to put the video on top of a cube, but that...

Selecting FPGA synthesis, place and route and simulation tools
Hi, We're considering using the Xilinx Spartan FPGA series. We plan to use the free Web ISE tools for doing our verilog synthesis, place and route and simulation. I have several questions about this. I'm assuming that synthesis and pnr are well taken care off by the Web ISE. However, I noticed simulation might have to be done using ModelSim and rather than being free it is provided only with time limited licensing. Are there alternatives to ModelSim? We used to use Cadence's ncsim but we will not have funding to use it anymore. We were using verilog and C testbenches through PLI ...
