Matter with MUL (*)
Here is a sample code for what I'm getting of. ( I'm using ISE10.1 ) The problem is ISE omits the second operand in multiplication. This simple code is synthesized as a signed MUL with one input is "a" and the second input is left open. What is the matter with ISE? Or what is my fault? I'm lost my calm! Pls help me!
PS: Thanks in advance
Code:
library IEEE;
use IEEE.STD_LOGIC_1164.all;
use IEEE.NUMERIC_STD.all;
entity Demo_MUL is
port(
a,b : in signed(4 downto 0);
s : out signed(9 downto 0)
);
end Demo_MUL;
architecture Behavioral of Demo_MUL is
begin
s <= a * b;
