    Subject: [oc] vhdl question
    Top
    Hey guys,
    I had a question. I have a combinational statement in VHDL as given below.
     
    start <= '1' when read='1' and addr(7 downto 0)="11111111" else '0';
     
    Now what happens here is that read goes high only for one clock cycle and hence so does start. How can I make start stay high for 2 or more clock cycles and then go low ?
