ModelSim RGB Singal -> Image ?

[Michael Schmid]

Hi,

i am doing some VGA Output in ModelSym.
My vhdl Creats a R, G, B, vSynv, hSync and Blank.
The Waveform Output of the Testbench looks nice, but actually doesn't
mean anything to me.

Is there any way to make a nice looking Image (bmp, jpg, ..) out of the
Singals?

Thanks in Advice.

if you have a prototyp board, then you can just program it and plug-in a
VGA monitor, like I've done: http://www.jroller.com/page/fb

The VGA input is connected with a resistor to the FPGA output, see
http://www.xilinx.com/products/spartan3/boards/s3_board_sch.pdf , page 7. I
think this is very clever, but it gives you only 8 colors, but for testing
this is enough.
