am trying to create an rs232 serial interface btw an FPGA and a pc. using verilog on xlinx. how do i set up xlinx in order to use verlog? and how do i create an rs232?
You need two things:
1. RS-232 transceiver - IC which translates the levels of CMOS/TTL to RS-232. for example MAX3232 - MAXIM
2. In your FPGA you should have a UART block. You may get from OPENCORE.org
It is not hard to program your device by interfacing with RS232.
First of all, i agree wat KHaila has commented you.
if you want to learn more you can do some research on UART (Universal Asynchronous Transmitter/ Receiver).
