Test pattern + VGA

Hi all

I am trying to use the VIP with the DE2 board.

To begin, I'd like to generate a test pattern and show it trough the VGA.

The REAL problem is that I don't have ny idea on how connect VGA and test pattern.

I don't know if I have to use a pixel buffer, or a frame buffer, if is better using "DE clock for external boards" function or using a pll created with megawizard..

I REALLY don't know how to begin.

Is there anyone that, please, could help me?
