Mister, I’m using xilinx ISE 14.1 and i’m getting an issue with the operand and multiple driver while applying radix 4 FFT.

however ,

from g2 really you will find three expressions arising. i’m not able to utilize any operand among them like and/or/+ so will be able to avoid writing three occasions g2() that is only problem of multiple driver.

the mistake is High-density lipoprotein parser 808. and can’t be any operand such context like this. what exactly must i do plz help

I’m also attaching the snapshot from the prob.

Despite the fact that i’ve attempted to transform individuals expressions in binary after which make use of the + operand among but nonetheless exactly the same problem persist. as well as i attempted with declaring function within the package with “and” however in in either case also i wasn’t in a position to solve the issue. so help me

Without seeing the way the functions add() and mult() are declared, you cannot offer any assistance.

library IEEE

use IEEE.std_logic_1164.all
use IEEE.MATH_REAL.ALL

package fft_pkg is

type complex is
record
r. real
i. real
finish record

type comp_array is array ( to fifteen) of complex
type comp_array2 is array ( to 9) of complex

function add (n1,n2. complex) return complex
function sub (n1,n2. complex) return complex
function mult (n1,n2. complex) return complex

package body fft_pkg is

–inclusion of complex figures
function add (n1,n2. complex) return complex is

variable sum. complex

begin
sum.r:=n1.r + n2.r
sum.i:=n1.i + n2.i
return sum
finish add

similarly for addition and subtraction
