title: Tristate buffers in Quartus II
body: <p>I need to clear up a problem with an external input to a CPLD by putting it through a tristate buffer. I know Quartus II has a tristate-buffer megafunction, but I am curious - if I simply tell it to output Z on the specific pin, will in automatically synthesize so the tristate buffer is enabled on that pin, or do I have to implement the function/write a buffer?</p>
