How to import data for VHDL testbench for 1024 point FFT in Xilinx Ise 9.1i?

[dhawalkadao]

I am implementing a 1024 point FFT using Xilinx ise 9.1i. Is there a way I can import the data for test bench automatically, using Matlab or any other text file.

Xilinx Ise 9.1i

Which language is your test bench? Most languages provide file I/O function for reading and writing data files during simulation. For instance, Verilog provides $fopen, $fgetc, $fread, $fscanf, $fclose, and others that are similar to C functions.

Thanks for the reply. The test bench is using VHDL. I am using VHDL to implement my design.

Hi !!!
You should look into Edit-> Language template
VHDL-> Simulation construct-> assertions & functions -> file I/O -> read:write to a file

Here are listed all the functions that you need....

Good luck
