What is the difference between IC chip design and logic design, FPGA design?

Simply put, chip design, pre-function and then simulation, can be written in verilog, run out of the version needs to be used to verify the function of the FPGA, when the end of the function verification needs to be ported to the ASIC code, made into a netlist, and then flow, so that the new chip is also designed. So the chip design and FPGA work is similar, FPGA design is only concerned about the function of simulation, and in the FPGA implementation, do not need to be made into an ASIC. and chip design and FPGA designers can be categorized into the logic design this piece.
