What is an FPGA

VHDL - Says SHOW its FUNCTION it doesnt necissarilly have to be WORKING its just a IMPLEMENTATION MODEL
or MACH....

HLS - a DRIVER or MACH that says this HARDWARE is going to SERVE ITS PROGRAMMED PURPOSE...... like working the wheel backwards....

VERILOG - how is your FPGA going to FUNCTION based on what it is actually specified as MACH but its ACTUAL implementation
your at the same point you started at..

C/C++ - how are you going to do this so ok... LINUX...
