FPGA as an arbitrary waveform generator

Postby oldfoggy » Mon Jul 05, 2010 3:10 am

Hi all I'm a beginner to FPGAs and VHDL. I have a project in which the FPGA is to be used as an arbitrary waveform generator. The FGPA I'm using is the Xilinx Spartan 3A DSP 1800 board.

The idea I have for implementing this is to generate the required waveform from another program, e.g. Matlab, and send the generated values of the waveform into the FPGA. After which I will connect to a DAC (Digital-to-Analog Converter) in order to output the waveform which can then be observed by an oscilloscope.

The issue I am facing now is the method of sending the data from the PC to the FPGA and storing the data in the FPGA. Can anyone advise on this? If I were to use a RS232 connection, how do I send the data across?

Thanks in advance... :)
