Hi members, I am a student and completely new to FPGA. I am learning VHDL. My objective is to implement FFT in spartan-3 starter kit. I would like to know how many months it will take me to fully design it. As a novice i would like to know few suggestions and references for my project. I need help. I don't know from where to start.
The answer depends mainly on you and you ability to grab new tools and to analyse the problem.
FFT is a repetitive design, but it consumes lots of FPGA resources.
Now, what I think (worst case and the time schedule is not linear, every task is intermixed with the others):
a) learning the tools (VHDL, ISE, and ModelSim) to get the profficicency required: 1.5 months
b) dividng the FFT in separated design blocks: 0.5 months
c) writing the VHDL models, analysing and correcting: 1 .5 months
Important: you have to select the correct Sparatan 3 chip with enough resources for your task and with a footprint according to the PCB technology you have available (not everyone can use FPBGA)
Finally, there is an optional step d): This Eureka! you find after doing most of the work, that makes you restart form scratch... 1.5 extra months
Anyhow, I repeat this is a worst case evaluation. As you are a student, it should be easy for you to learn the use of VHDL withn Xilinx ISE and Modelsim faster than that. The rest depends on your talent and training, which I will judge by no means.

Hi Biot, have a look at
