what ic do i need

The design rules guarantee that the non-idealities and imperfections during fabrication ( that usually come from imperfections in material, control steps and photo lithography limitations) do not affect the functionality of you circuit

If design rules are violated the odds that you get unwanted shorts and opens in the circuit increases and most likely your chip would be useless.
