Hi all , I am a newbie of FPGA. So in the development chain I miss the following step: Suppose I have developed and tested my VHDL code, example an FFT. How can set a parameter (i.e FFT dimension) inside the VHDL code from the HOST PC? I need a driver. In which way this dirver have to be developed ? Thanks in advance
Host driver

You also need to code the way the parameters are set in HDL, including the hardware interfaces Common choices to interface with a host PC are - JTAG - RS232 - Ethernet - USB - PCI Or there might even be no host PC. Maybe you are running Linux on a processor implemented in you FPGA and the user enters the parameters with EMACs. If you just want to test modules and have no whole system yet to implement in your FPGA you can use ChipScope that has an option to set Vitual IOs from a PC using Chipscope. Joysticks, Pushbuttons, PS2-Keyboards are very easy to interface to in hardware and can also be used to set parameters.
