thanks dude

but what you have is the way i know, where u do the decoding urself.

what i mean is a component that when the input is "0000" gives u the output "1000000" and so on.

If you have a 4-bit register, or say a Qsys system with a PIO component, and you connect those 4-bits to the hex_display input, and the hex_display output to the 7-segment display, then when you write 0, 1, 2, 3, .. E, F, the display shows the corresponding hex values.

Cheers,
