what are all the software required for download VHDL program under kit?
Preveen, Downloading VHDl program in to FPGA depends on which FPGA vender IC you are using?
For instance, If you are using Spartan-3 FPGA manufactured by xilinx Inc, you must use Xilinx ISE software there is no other alternatives.
If you are using Cyclone-3 FPGA manufactured by Altera Inc, you must use Quartus II software.
I hope this clarify your doubt.
