Hi,
It seems that the following construction is not allowed in GHDL.
----------------------------------------
library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;
entity test_attribute is
port(
clk: in std_logic;
reset: in std_logic;
toggle: out std_logic
);
end;
architecture first of test_attribute is
attribute max_fanout: string;
attribute max_fanout of toggle: signal is "100";
signal toggle_i: std_logic:='0';
begin
process(clk)
begin
if rising_edge(clk) then
if reset='1' then
toggle<='0';
toggle_i<='0';
else
toggle<=not toggle_i;
toggle_i<=not toggle_i;
end if;
end if;
end process;
end;
----------------------------------------
When I try to compile this code, GHDL produces the following message:
test_attribute.vhd:16:25: no named entities 'toggle' in declarative part
This construction is required for xst (xilinx) and works fine with
modelsim.
greetings,
Mark.
