Design of UART controller for FPGA with Simulink®

Simple UART (Universal Asynchronous Receiver Transmitter) controller, compatible with RS232 standard is implemented on Spartan-3E FPGA, through automatic HDL code generation and hardware synthesis. The paper shows how the design can be entirely conveyed in MATLAB/Simulink® environment. There is no need for additional behaviour description in HDL. Results from simulation and experiments verify functionality of the controller.
