I post a component. A vga sync generator for 640 x 480 resolution. Its inputs are:

clk

rst

ptick -- a clock enable, when your system clock is not 25MHz.

Its outputs are:

x

y

vsync -- registered

hsync -- registered

video_on -- place red, green and blue only when this is active.

I used in many design. It works.
