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.
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.
