How redirect an analog signal to another pin.

[Altera_Forum]

Hello, It's possible redirect an analog input signal to another pin in FPGA (DE0 nano), or a way to implement a simple buffer DAC on VHDL ? 

 I'm trying to multiplex signals provided from a vga controller to make a video wall. But, as red, blue and green signals are analog, i can't redirect this signals to be displayed.

No, it's not. FPGAs are digital devices. So, there's no point in connecting an analogue signal to an FPGA pin (on the DE0 Nano anyway). You could control an external DAC using VHDL but you can't implement one in the FPGA. 

 I don't think you're considering an appropriate solution for your problem.  Cheers, Alex
