Hello.
I am using a global buffer input as clock input, the signal then goe
through a DCM, and I need to output the inverted clock through a pin int
another chip. Can I use any pin for this clock output or are ther
specific pins that better serve this purpose?
Thanks.

a,
Any pin will function.
"Better" is a relative term: there are pins with less delay from the
pad on the die to the pin on the package, would you call this better?
If this is what you want (the shortest delay), you need to look at the
delay from the pad to the pin in the package.
This delay is commonly called "flight-time."

You can use any pin. Its best to use a DDR flipflop in the IOB.
