Here is an example of the code problem I inherited.

--- Quote Start ---

entity example is

port

(

flash_data : inout std_logic_vector(7 downto 0));

end entity example;

architecture rtl of example is

signal flash_data_internal : std_logic_vector(7 downto 0);

begin

--this works in quartus 5.1 but not 6.0 and above

flash_data <= flash_data_internal;

flash_inst: entity work.flash(rtl)

port map

(

flash_data => flash_data_internal --flash_data is inout in flash.vhd

);

--this is the proper way

flash_inst: entity work.flash(rtl)

port map

(

flash_data => flash_data --direct to the input port.

);

--- Quote End ---

The flash_data_internal signal allows the data to go out but provides no path for the data coming in.
