    So, try to do this,

    clk_process: process

    begin

    clk<=NOT clk;

    wait for 10ns;

    end process;

    I think this is the better way to generate a clock signal for test bench.

    Good luck!!

    You forgot semi colons in your code.

    How about posting the real code, and the real errors next time.

    And Shikata: your code would not work if you forgot to initialise clk - the OP's code will.
