code snipets:
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;
entity TEST is port (
addr : in integer range 0 to 31;
end TEST;
component TEST port (
addr : in integer range 0 to 31;
end component;
DBUS : inout std_logic_vector(15 downto 0);
Inst_TEST: TEST port map (
addr => to_integer(unsigned(DBUS(4 downto 0))),
);
This is where I get the ISE error:
Actual, ParameterAssocOp, associated with
Formal Signal, Signal 'addr', is not a Signal. (LRM 2.1.1)
What am I doing wrong here?
> What am I doing wrong here?
Mapping "inout" to "in" port?
Try it with a local signal:
1 | :
|
2 | :
|
3 | |
4 | DBUS : inout std_logic_vector(15 downto 0); |
5 | addrhelp : integer range 0 to 31; |
6 | |
7 | |
8 | |
9 | addrhelp <= to_integer(unsigned(DBUS(4 downto 0))); |
10 | |
11 | Inst_TEST: TEST port map ( |
12 | addr => addrhelp |
13 | );

In this way no function or procedure is called within the port assignment...
