But I would like to know if I don't have USB-to-serial adapter cable, are there other ways to convert it in software ?
sorry I am beginner in FPGA.

Why don't you start by telling me what type of FPGA board you have. Most FPGA boards have a JTAG connector that you can use to program them with. If you have a sufficiently recent FPGA, then you can also use JTAG to communicate with logic inside the design. You can learn about that method here
