Hi,

the code you provided is'nt synthesizable at all; it seems like you try to synthesize a bevahioural model for simulation.

the correct process would include a sensitivity list with asynchronous reset and the clock input like

MyStateReg : process (inResetAsync, iClk) is

begin

if inResetAsync = cnAcivated then

elsif rising_edge(iClk) then

-- here is your stuff

end if;

end process;

However, I would recommend using the 2 process method as proposed by Gaisler (Gaisler Research) to keep your design readble, servicable and 100% synthesizable.

regards,
