Hi dears all,

Concerning the RAZ in my design, do you suggest that I don't need it?

For the prescaling, I use it because I make some tests on my nexys2 with some led.

I try each function step by step by visual inspection of the status led because when I start to use XILINX ISE, Idon't know how to use the simulator so I count the status of the led... . to be sure my design run

Now, I understand how to use the simulator.

In the same way, I use every day this calculator => TI-30 from Texas instrument.

Right now, I'm going to use the clock at 50MHz from internal crystal.

Then, pixel time will be at 20ns.

I need to change all valu of my counter, this is not a big issue.

I make the change you tell me concerning this :

if hcs < 63 then hsync <= '0';
else hsync <= '1';
endif;

Have a nice day.

Frédéric Cabanes.
